A350 LF2 CL.1 WN RF SF Flange

What is ASTM A350 GR LF2 Cl 1 material?

ASTM A350 LF2 Flanges are designed for low temperature and ambient temperature pipeline applications. The flanges are composed of minor amounts of carbon, silicon, manganese, phosphorus, sulfur, molybdenum, copper, chromium, nickel, vanadium and niobium. Multi Metals (India) is a leading manufacturer and supplier of A350 Lf2 Cl1 Flanges in diverse sizes and shapes. The material exhibits high strength, with a minimum tensile strength of 655MPa, minimum yield strength of 250MPa, 22% elongation, and 197HBW Brinell hardness. These flanges can be normalized or tempered to further enhance their hardness. The LTCS ASTM A350 Lf2 Flanges support various forming operations such as forging, rolling and machining.

The flange sizes typically range from ½ inch to 64 inches. The flanges come in different pressure ratings based on the wall thickness, diameter, and heat treatment process. There are pressure classes ranging from 150 to 2500, as well as PN6, PN10, PN16, and others. The flange schedules cover a wide spectrum, from sch10 to XXS, and custom schedules are also available. Different connection types require the use of corresponding flange designs, including flat face, raised face, and ring type joint. The A350 Lf2 Grade Pipe Flanges are also offered in various functional types, such as welding neck flanges, slip-on flanges, and lap joint flanges, each suited for specific applications.

The A350 Gr Lf2 Cl1 Weld Neck Flanges are used to securely hold the pipes during welding, providing a stronger grip. Most flanges are welded for improved tightness, though threaded and bolted options are also available. Both A350 Gr Lf2 Class 1 and Class 2 Slip-On Flanges are offered, with Class 2 having higher mechanical properties. Our company, C&N Huitong, is a professional flange and pipe manufacturer from China.
