Harsh Steel is a specialized manufacturer of high quality ASME/ANSI/DIN standard screwed flanges in India. Screwed Flanges are broadly used in low pressure piping systems, as no welding is involved while connecting the flanges to pipes or other equipment. Though, the flange may be welded around the joint after assembly, but it is not considered a satisfactory method of increasing its applications. Harsh Steel is a master in exports of Carbon Steel Screwed Flanges LF1, LF2 CL1/CL2, LF3 CL1/CL2, A694 F42, F46, F48, F50, F52, F56, F60, F65, F70, A516.60, 65, 70 (Spectacle Blind Flange, Spacer Ring/Spade Flange), Steel RST37.2, C22.8; Stainless Steel Screwed Flanges F202, F304/304L/304H, F316/316L, F316H, F316TI, F310, F321, F904L; and Alloy Steel Screwed Flanges F1, F5, F9, F11, F22, F91.Our products are widely exported to countries and regions such as the United States, Europe, Russia, Turkey, Malaysia, the UAE, Saudi Arabia, Iran, Brazil, Chile, Mexico, South Africa, Jordan, Tunisia, Vietnam, Indonesia, Thailand, Singapore, Colombia, and Sri Lanka.
