Duplex Steel 4A 5A 6A Plug Valve Material characteristics:

For precipitation hardening stainless steel, they are in ferrite matrix containing 35% ~ 40% austenite, its yield strength is about 2 times of 19Cr-9Ni austenitic stainless steel, and has high hardness and good plasticity and impact toughness. Especially suitable for both abrasion and erosion corrosion working conditions, so widely used in oxidation and reduction of strong acid conditions, in the chlorine environment has a special stress corrosion cracking resistance performance.

Good activation and passivation conversion ability, excellent corrosion resistance, in non-oxidizing acids such as sulfuric acid, acetic acid, formic acid, phosphoric acid has good corrosion resistance, in neutral chloride ion medium has good pitting resistance, at the same time has good crevice corrosion resistance and stress corrosion resistance.
