Astm A182 347 1.4550 304 Orifice Union For Welding Plate Wled Flange
Stainless steel flange simplified as SS flange, it refers to the flanges that made of stainless steel. Common material standards and Grades are ASTM A182 Grade F304/L and F316/L, with pressure ratings from Class 150, 300, 600 etc and to 2500.
Grade 304 is an alloy that is very ductile. Therefore, this material is easily formed into various products including flanges. Primarily sought after for its economical value, the use of Stainless Steel 304 Flanges is typical in applications that require limited corrosion resistance properties. Stronger than most carbon steel grades, these flanges have lower strength and resistance properties over grade 316.
