Material of stainless steel flange
Classification:
Release Time：2019-04-01
Stainless steel flange material is made of different models and different uses, chemical composition and production. Stainless steel can be generally classified according to its use, chemical composition and metallographic structure. 1. stainless steel flanges are classified by chemical composition: 1. CR series: ferrite series, martensite series 2. CR-NI series: austenite series, abnormal series, precipitation hardening series. 2. stainless steel flanges are classified by metallographic structure: 1, austenitic stainless steel 2, ferritic stainless steel 3, martensitic stainless steel 4, duplex stainless steel 5, precipitation hardening stainless steel 3. stainless steel flanges have the following materials: 1, material 301-
Stainless steel flange material is made of different models and different uses, chemical composition and production. Stainless steel can be generally classified according to its use, chemical composition and metallographic structure.
1. stainless steel flanges are classified by chemical composition: 1,CRSeries: ferrite series, martensite series2,CR-NISeries: austenite series, abnormal series, precipitation hardening series.
2. stainless steel flange with metallographic organization classification: 1, austenitic stainless steel2Ferritic stainless steel3martensitic stainless steel4Duplex Stainless Steel5Precipitation hardening stainless steel
3. stainless steel flanges are made of the following materials:
1. Material301-Good ductility, used for flange molding products, can also be quickly hardened by mechanical processing, good weldability, wear resistance and fatigue strength is better304Stainless steel.
2. Material302-Same as corrosion resistance304,The strength is better due to the relatively high carbon content.
3. Material303-By adding a small amount of sulfur, phosphorus to make it more304Easier cutting.
4. Material304-Common type; I .e.18/8Stainless steel.
5. Material309-compared304It has better temperature resistance.
6. Material316-Following304After that, the second most widely used steel grade
7. Material321-Other properties are similar except that the risk of corrosion of the material's welds is reduced due to the addition of titanium.304.400 Series-Ferritic and martensitic stainless steels.
8. Material408-Good heat resistance, weak corrosion resistance.
