ASTM A105 Flange is a specification for flanges. Specifications can include flanges of various grades made of stainless steel. The flange is made of forged Carbon Steel ASTM and is intended for high temperature use. Shasan Piping Solution is a leading manufacturer and supplier of ASTM A105 flange types.

TThis material contains carbon, manganese, phosphorus, sulfur, silicon, copper, nickel, chromium, molybdenum, and vanadium. These are called Carbon Steel ASTMs because other materials contain less than 1% of the composition. There are different types, including SA105N blind flanges, which are used to close pipelines. The flange also has excellent strength properties. The minimum yield strength of the flange is 250 MPa and the minimum tensile strength is 485 MPa. It is a hard material with a Brinell hardness of 187.

There are various pressure classes such as class 150, 300, up to 2500, and PN6 to PN64. A105 flanges of class 300 and below do not require heat treatment, but high pressure class can be heat treated. Flanges with a nominal internal diameter greater than 4 inches are heat treated as annealing, normalizing, normalizing and tempering, or normalizing and tempering. ASTM A105 pipe flanges can also be forged. This material is suitable for welding applications. When welding materials, boilers, and pressure vessels, guidelines consistent with ASME standards must be followed. Flanges are both bolted and bolted. ASTM A105 N threaded flanges are useful when welding or screwing methods are not suitable. Threaded flanges can be used on threaded pipes to create connections without welding.
