forged alloy blind flange A182 F12 plate flange
ASTM A182 F12 alloy steel flanges also contain niobium to prevent sensitization and resulting intergranular corrosion.
The material specification for forging can be described as ASTM A182 Gr. F12 Cl.2. The alloy steel grade most commonly used to produce bare forgings is f12 cl 2. In addition, they are used to produce forged or machined products, mainly in high temperature applications. The ASTM A182 specification includes many requirements, including mechanical quality, heat treatment, chemical composition, and other supplemental requirements. At the same time, the alloy steel F12 flange also has strong resistance to chloride solution pitting corrosion, crevice and stress corrosion cracking ability. Due to the low carbon content, F12 alloy steel socket weld flanges have absolutely no risk of intergranular corrosion when cooling or welding.
