Product Description

Material Characteristics

• 1. Material Characteristics

   

  • Chemical Composition and Microstructure: Stainless steel PS8 used in the rubber and plastic industry contains key elements such as approximately 16% - 18% chromium and 10% - 12% nickel in its chemical composition. The chromium element forms a dense and relatively strong self-healing chromium oxide protective film on the surface of the stainless steel, which effectively resists the erosion of various chemical substances that may be encountered during the processing of rubber and plastics, such as rubber vulcanizing agents, plastic additives, as well as humid air, acidic or alkaline substances in the processing environment. The nickel element endows the stainless steel with good toughness and ductility, enabling it to adapt to mechanical effects like vibrations and impacts generated during the operation of rubber and plastic machinery, and it is less prone to brittle fracture. Its microstructure is uniform and dense, with crystals arranged in an orderly manner. This structure helps improve the strength and anti-fatigue performance of the stainless steel, allowing it to maintain stable performance under the condition of long-term exposure to complex stresses.
  • Physical Property Indicators: It has excellent strength and hardness characteristics. The tensile strength is roughly between 550 and 650 MPa, and the yield strength is approximately 250 to 300 MPa. Such strength levels enable it to withstand the forces acting on key components such as screws and barrels in rubber and plastic machinery under high-temperature, high-pressure, and high-torque working conditions, ensuring that the components will not be easily deformed or damaged. The Rockwell hardness (HRC) ranges from 28 to 32, with a moderate hardness that is conducive to mechanical processing such as cutting, drilling, and milling to meet the manufacturing requirements of different components. At the same time, it can maintain good wear resistance during contact and friction with materials like rubber and plastics, reducing the decline in component precision and equipment failures caused by wear. Its coefficient of thermal expansion is relatively low, approximately 16 - 18 × 10 / °C. During the operation of rubber and plastic machinery, when temperature fluctuations occur due to friction heat or environmental temperature changes, it can effectively control the dimensional changes of components and maintain the precise fit between various components of the equipment to ensure its stable operation.

   

  1. Processing Performance

   

  • Cutting Processing Performance: It performs well in cutting processing. Due to its moderate hardness and stable organizational structure, by using appropriate tool materials (such as cemented carbide tools) and adopting optimized cutting parameters (the cutting speed is generally between 100 and 150 m/min, the feed rate is 0.1 - 0.2 mm/r, and the cutting depth is 0.5 - 2 mm), high-precision cutting processing can be achieved. For example, when processing shaft parts in rubber and plastic machinery, the surface roughness after processing can be controlled within Ra1.6 - 3.2 μm, and the dimensional accuracy can reach ±0.03 mm, meeting the strict precision processing requirements of the rubber and plastic industry for parts. Meanwhile, it has good chip-breaking performance. The chips generated during the cutting process have regular shapes and are easy to clean up, which can effectively avoid problems such as processing interruption and tool damage caused by chips winding around the tool, improving processing efficiency and quality.
  • Forming Processing Capability: It has excellent forming processing capabilities and can adapt well to both cold forming and hot forming processes. In terms of cold forming, such as cold rolling and cold bending operations, its good ductility enables stainless steel PS8 to be processed into various complex-shaped components of rubber and plastic machinery, such as the barrel housings of extruders and mold frames. For example, through the cold rolling process, stainless steel PS8 sheets with a thickness of 2 - 5 mm can be processed into mold side panels with specific arcs and shapes without cracks or fractures during the processing. In hot forming, after being heated to an appropriate temperature range of 950 - 1100 °C, its plasticity is further enhanced, and it can be used for forging, hot rolling and other processing to manufacture key load-bearing components of large rubber and plastic machinery, such as the large tie rods and screws in the clamping mechanism of injection molding machines. The internal structure of the formed components is uniform and the performance is reliable, which can meet the usage requirements of rubber and plastic machinery under high-intensity and high-load working conditions.
  • Welding Performance Characteristics: It has excellent welding performance and can adopt multiple welding methods, such as manual arc welding, argon arc welding, and carbon dioxide gas shielded welding. During the welding process, due to its stable chemical composition and good fluidity, the weld seam has a beautiful shape and is not prone to welding defects such as pores, cracks, and slag inclusions. When welding, by selecting welding materials similar in chemical composition to the base metal (such as matching stainless steel welding wires) and reasonably controlling parameters such as welding current, voltage, and welding speed, the strength and corrosion resistance of the welded joint can be ensured to be equivalent to those of the base metal. For example, when using argon arc welding to weld stainless steel PS8 sheets with a thickness of 4 mm, the welding current can be controlled between 100 and 130 A, the voltage is 12 - 16 V, and the welding speed is approximately 8 - 12 cm/min. The strength of the welded joint after welding can reach more than 95% of that of the base metal, and it has good corrosion resistance in the working environment of the rubber and plastic industry, ensuring the integrity and performance stability of the overall structure of rubber and plastic machinery and prolonging the service life of the equipment.

   

  1. Application Components in Rubber and Plastic Machinery

   

  • Screws and Barrels: Screws and barrels are the core components of rubber and plastic extrusion machines, injection molding machines and other equipment. The high strength, high wear resistance and good chemical stability of stainless steel PS8 play a crucial role in these components. During the processing of rubber and plastics, the screw rotates at high speed inside the barrel to perform operations such as conveying, compacting, plasticizing and mixing of materials, while the barrel has to withstand high temperature, high pressure as well as the friction between materials and the screw. Stainless steel PS8 can withstand these harsh working conditions, ensuring a long service life for screws and barrels and reducing problems such as fluctuations in material quality and declines in production efficiency caused by component wear or corrosion.
  • Molds and Mold Frames: Stainless steel PS8 is an ideal material for the manufacturing of rubber and plastic molds and mold frames. Molds require precise shapes and sizes to form rubber and plastic products that meet requirements. The high strength and good processing performance of stainless steel PS8 can ensure the precision and surface quality of molds. Mold frames need to provide stable support and positioning for molds. Their good rigidity and corrosion resistance can ensure that they will not be affected by deformation due to force or erosion by chemical substances during long-term use, thus improving the molding quality and production efficiency of rubber and plastic products.
  • Mechanical Frames and Protective Components: The frames and protective components of rubber and plastic machinery made of stainless steel PS8 can provide solid structural support and effective protection for the equipment. As the skeleton of the equipment, the frame needs to have sufficient strength and rigidity, which stainless steel PS8 can meet. Moreover, its corrosion resistance can prevent rust and corrosion in the humid and chemical-rich environment of rubber and plastic processing workshops, prolonging the service life of the equipment. Protective components can protect operators from being injured by moving mechanical parts and prevent dust, impurities and other substances from entering the interior of the equipment to affect its normal operation. Its metallic luster and the property that it can be subjected to surface treatments (such as painting, electroplating, etc.) make it more aesthetically pleasing in appearance, meeting the requirements of the equipment image in modern rubber and plastic production workshops.

  Advantages

This characteristic greatly reduces the frequent maintenance and component replacement due to equipment corrosion, lowers the production cost, and at the same time ensures the long-term stable operation of rubber and plastic machinery and improves production efficiency. For example, in a large rubber and plastic processing factory, equipment made of stainless steel PS8 has a very low degree of corrosion after continuous operation for many years. Compared with traditional carbon steel equipment, it significantly reduces the downtime and maintenance costs caused by corrosion.
