Usually, most forged Flanges manufacturer of India follow specification ASTM A350 or standard ANSI B16.5 for the manufacture of components i.e. forged flanges. ANSI B16.5 standard covers testing, materials, dimensions, pressure-temperature ratings, tolerances, marking, and methods of designating openings for pipe flanges for e.g. stainless steel forged flanges and flanged fittings. A350 LF2 forged Flanges are a general Carbon steel grade component that is supplied in any of the following conditions i.e. Normalised condition, Normalised and Tempered condition or Quench and Tempered condition. Carbon steel LF2 grade are typified as having moderate tensile strength and impact toughness properties.
ASME B16.5 Forged Flanges
Stainless Steel Forged Flanges
Carbon Steel Forged Flanges
Hence this grade is extensively considered to be ideal for the manufacture of forged flanges. The carbon steel forged flanges belonging to grade LF2 are regularly a part of applications that has requirements relating to cold temperature settings where corrosion resistance is a property that is not considered to be important. Forging can be practised on several alloys including carbon steel, alloy steel, stainless steel or superalloys. Forging, when practised on several alloys is what provides them with better mechanical properties. For instance, there is an increase seen in the ANSI B16.5 forged Flanges properties such as ductility and fatigue resistance as well as impact resistance. This is because a forging process not only refines but also directs the grain flow according to the shape of the piece.
