What are the materials of stainless steel socket flange?

　　1. Stainless steel socket flange Material 301-good ductility, used for flange forming products, but also through mechanical processing to make it rapidly hardened, good weldability, wear resistance and fatigue strength better than 304 stainless steel.

　　2. Stainless steel socket flange Material 302-corrosive resistance is the same as 304, and its strength is better because of its relatively high carbon content.

　　3. Stainless steel socket flange Material 303 - By adding a small amount of sulfur and phosphorus, 1/2"-72" 3000lbs Weld Stainless Steel Socket Flange is easier to cut than 304.

　　4. Stainless steel socket flangeMaterial 304 - General model; 18/8 stainless steel. GB is 0Cr18Ni9.

　　5. Stainless steel socket flange Material 309-has better temperature resistance than 304.

　　6. After Stainless steel socket flange material 316-304, the second most widely used steel is mainly used in food industry and surgical equipment, adding molybdenum to obtain a special corrosion-resistant structure. Because of its better chloride corrosion resistance than 304, it is also used as "marine steel". SS316 is usually used in nuclear fuel recovery devices. Stainless steel grade 18/10 usually meets this application level.

　　7. Stainless steel socket flange Material 321 - Except for reducing the risk of corrosion due to the addition of titanium, other properties are similar to 304. 400 Series - Ferritic and Martensitic Stainless Steel.

　　8.Stainless steel socket flange  Material 408 - Good heat resistance, weak corrosion resistance, 11% Cr, 8% Ni. Model 409 - The cheapest model (British and American), usually used for automobile exhaust pipe is ferritic stainless steel (chromium steel). Model 410 - martensite (high strength chromium steel), good wear resistance, poor corrosion resistance.
