Precipitation hardening stainless steel made of stainless steel flange, whose matrix is austenite or martensite, and the common brand of precipitation hardening stainless steel made of stainless steel flange is 04cr13ni8mo2al, etc. It is a stainless steel flange material that can be hardened (strengthened) by precipitation hardening (also known as age hardening). Martensitic stainless steel made of stainless steel flange has high strength, but poor plasticity and weldability. The commonly used brands of martensitic stainless steel made of stainless steel flange are 1Cr13, 3Cr13, etc. because the carbon containing stainless steel flange material is high, it has high strength, hardness and wear resistance, but the corrosion resistance is slightly poor. It is used on some stainless steel flanges with high mechanical performance requirements and general corrosion resistance requirements, such as springs, turbine blades, hydraulic turbine valves, etc. This kind of steel is used after quenching and tempering. Stainless steel flange material needs annealing after forging and stamping.
Stainless steel plates and strips are used for pressure equipment made of stainless steel flanges, and stainless steel for pressure vessels. The classification and code, size, shape and allowable deviation, technical requirements, test methods, inspection rules, packaging, marks and product quality certificates of stainless steel flanges.
Application of stainless steel flange alloy, nickel alloy made of stainless steel flange can be used in the following industries:
1. Heat treatment industry. Such as furnace roller, bell furnace and annealing furnace.
2. Calciner. For example, it is used to calcine corundum with high performance, calcine chromite to produce ferrochromium alloy, and recover nickel used as catalyst in petrochemical industry.
3. Chemical and petrochemical industry, with which new steam cracking crude oil furnaces are prepared to produce hydrogen, etc.
4. Automation device. Such as catalytic support system, spark plug.
5. Cleaning equipment for nuclear industry, such as nuclear waste removal.
6. Steel industry. Such as direct reduction of iron ore process to produce sponge titanium.
