ASTM A192/SA192 Boiler Tube

Views:4    

ASTM A192 boiler tubes are made of grade 192 stainless steel that has undergone numerous test sample hardness tests, flattening tests, flaring tests, flange tests and hydraulic tests. We basically manufacture these ASTM A192 boiler tubes according to the seamless cold drawn process to maintain their smooth surface texture and stabilize their chemical composition
