Material:Stainless Steel SUS304
SUS304 material is a Japanese JIS standard and the most commonly used stainless steel, containing 18% Cr and 8% Ni. It can maintain good strength and heat resistance in high temperature and low temperature environments, and also has good corrosion resistance, weldability, cold workability and mechanical properties in the mild atmosphere.

Face Type-FF Full Face
The Full Face flange has a gasket surface in the same plane as the bolting circle face. Applications use flat face flanges are frequently those in which the mating flange or flanged fitting is made from a casting.
Full Face-FF
according to the classification of gasket face and the designation of JIS B2220
