410 is a nickel-free
What are the mechanical properties of 00Cr12 stainless steel?
Ferritic stainless steel cannot be strengthened by heat treatment because there is no phase change. Generally, it is used after annealing at 700~800°C. Due to the similar atomic size of iron and chromium, the solid solution strengthening effect is small, the yield strength and tensile strength of ferritic stainless steel are slightly higher than that of low carbon steel, and the ductility is lower than that of low carbon steel. The specific mechanical performance parameters are as follows:
Elongation δ5 (%):≥22
Reduction of area ψ (%):≥60
Hardness: ≤183HB
What are the physical properties of 00Cr12 stainless steel?

- Specific heat capacity (0~100℃)/kq/(kg.k):0.46
What is the delivery status of 00Cr12 stainless steel?
Generally, it is delivered in a state of heat treatment, and the type of heat treatment is specified in the contract; if it is not specified, it is delivered in a state of no heat treatment.
The heat treatment specification for 00Cr12 stainless steel is annealing at 700~820°C, air cooling or slow cooling.
How is 00Cr12 stainless steel smelted?
At present, the smelting process for producing stainless steel in the world is mainly divided into one-step method, two-step method and three-step method, as well as a new integrated production method. The one-step smelting method is: molten iron + AOD (argon oxygen refining furnace); the two-step method is: EAF (electric arc furnace) + AOD (argon oxygen refining furnace). The three-step method is: EAF (electric arc furnace) + AOD (argon oxygen refining furnace) + VOD (vacuum refining furnace). In addition to several traditional production processes, the current integrated production process, that is, the production process from molten iron directly to stainless steel, is also adopted by many companies. The production process is: RKEF (rotary kiln electric furnace) + AOD (argon oxygen refining furnace).
How is the corrosion resistance of 00Cr12 stainless steel?
Ferritic stainless steel contains 11% to 30% chromium and has a body-centered cubic crystal structure. This type of steel generally does not contain nickel or a small amount of nickel, and sometimes contains a small amount of Mo, Ti, Nb and other elements. It has many unique characteristics and advantages. In the field of application, ferritic stainless steel is an excellent alternative material. Ferritic stainless steel does not contain nickel, and its main elements are chromium (>10%) and iron. Chromium is a particularly corrosion-resistant element of stainless steel, so 00Cr12 stainless steel is A steel with excellent corrosion resistance.
Can 00Cr12 stainless steel withstand high temperature?
00Cr12 Stainless Steel It can be forged at temperatures up to 2200°F (1200°C). This alloy does not work harden rapidly but can be heat treated to increase strength. 00Cr12 stainless steel resists scaling at temperatures up to 1600°F (870°C).
How about the corrosion resistance of 00Cr12 stainless steel?
The excellent corrosion resistance of 00Cr12 stainless steel is due to the presence of chromium and rare earth metals in its composition. In addition to corrosion resistance, 00Cr12 stainless steel also has a high strength-to-weight ratio, making it ideal for a wide range of applications.
What are the applications of 00Cr12 stainless steel?
The carbon content of 00Cr12 stainless steel is lower than that of 0Cr13, and the welding parts have good bending performance, processing performance and high temperature oxidation resistance. It is more suitable for automobile exhaust treatment devices, boiler combustion chambers, nozzles, heat-resistant equipment components, etc.
