C&N is a professional manufacturer of steel pipe fittings& steel forged flange in China,
We could produce high quality Stainless Steel SS321/321H Flanges,A182 F321 flange
Stainless Steel 321 is a basic austenitic 18/8 steel (Grade 304) stabilised by Titanium (321) addition. SS 321 is used because they are not sensitive to intergranular corrosion after heating within the carbide precipitation range of 425-850°C. Stainless Steel 321 is the grade of choice for applications in the temperature range of up to about 900°C, combining high strength, resistance to scaling and phase stability with resistance to subsequent aqueous corrosion. SS 321H is a modification of SS 321 with a higher carbon content, to provide improved high temperature strength.
