ASTM A182 Gr F6a | A182 Gr F6a | ASTM A182 Stainless Steel Flanges

ASTM A182 Gr F6a is a forged martensitic stainless steel with 13 wt.% chromium. Martensitic stainless steels can be high-carbon or low-carbon steel alloys. The ASTM standard A182 describes the general set of specifications about several material grades. These material grades, for example, ASTM A182 Gr F6a class 1, are unique materials with different properties.

ASTM 182 is a standard specification. This cover forged or rolled alloy and stainless steel pipe components to be used in pressure systems. Included are several grades of low-alloy steel, including martensitic, austenitic and ferritic-austenitic. The standard specification includes general requirements, manufacturing processes, and heat treatment processes. F 6a is a grade that describes specifically the steel type (martensitic etc.), heat treatment type, the austenitizing/solutioning temperature, cooling medium, quenching temperature, tempering temperature, composition and welding requirements. There are several classes of this grade including F6a Class 1, F6a Class 2, F6a Class 3 and F6a Class 4.

ASTM A182 Gr F6a Stainless Steel Flange Properties

ASTM A182 F6a, Classes 1 – 4 all have a specified chemical composition consisting of 11.5 – 13.5 wt.% chromium, 0 – 1.0 wt.% manganese, 0 – 1.0 wt.% silicon, 0 – 0.5 wt.% nickel, 0 – 0.15 wt.% carbon, 0 – 0.04 wt.% phosphorus and 0 – 0.03 wt.% sulphur. All four classes have the same value for the reduction of area. The specifications for other mechanical properties, however, vary between the classes. Comparing them, ASTM A182 F6a Class 1 has the smallest Brinell hardness, tensile strength and yield strength and ASTM A182 F6a Class 4 has the highest.

About ASTM A182 Gr F6a Stainless Steel Flange

A pipe flange is a disc, collar or ring that attaches to pipe with the purpose of providing increased support for strength, blocking off a pipeline or implementing the attachment of more items. Mesta Inc is ASTM A182 Gr F6a Flanges Manufacturers in India. They are usually welded or screwed to the pipe end and are connected with bolts. A gasket is inserted between the two mating flanges to provide a tighter seal. These flanges are either custom with dimensions provided by the customer or they are manufactured according to published specifications.
