When selecting the material model of stainless steel tensile parts, factors such as the material's ductility, elastic modulus, hardening index, corrosion resistance, and usage environment need to be considered. The following are some commonly used and high-performance stainless steel material models:
1Cr18Ni9Ti and 0Cr18Ni9Ti: These two material models are most commonly used in stainless steel stretching processes. Among them, 1Cr18Ni9Ti is more stable and has better crack resistance than 0Cr18Ni9Ti during the stretching process.
304 grade: This stainless steel material is also commonly used in the manufacturing of stretch parts. It has high corrosion resistance and is particularly suitable for environments that require resistance to salt water and chloride corrosion, such as ship components, stainless steel floats, and medical equipment. The tensile properties of 304DDQ and 304DDQS are also very good.
201 high copper material: For 201 series stainless steel, high copper material is a good choice with excellent mechanical and processing properties.
Please note that during the stretching process of stainless steel, due to its fast work hardening rate and increased friction caused by the chromium oxide layer, greater force is required for stretching. Therefore, when selecting materials, it is important to ensure that the selected model has good processability and ductility.
In addition, different models of stainless steel may have different prices, so cost factors need to be considered when choosing.
Overall, the optimal model for selecting stainless steel stretching parts depends on the specific application requirements and usage environment. In the selection process, it is recommended to have in-depth discussions with material suppliers or professional engineers to ensure that the selected materials can meet the performance requirements and production cost requirements of the product.
