All forgings duplex stainless steel as the characteristics of the pneumatic valve

Generally a small amount of phase is not less than %. So it has the ferritic stainless steel has high strength, resistance to chloride stress corrosion and austenitic stainless steel has the advantages of excellent toughness and welding performance.

( Pneumatic valve adopts integral forging processing or forge welding structure, and the nondestructive testing of qualified, solid solution treatment, fine material organization, because all for machining surface. Product appearance is beautiful. http://www。 zgbfw。 com/info/
( Pneumatic valve seal hard alloy spray welding. Can spray welding of nickel base welding powder, too vertical and tungsten carbide alloy material, hardness up to HRC has excellent abrasion resistance, improve the service life of the pneumatic valve. http://www。 zgbfw。 com/info/
( Due to the characteristics of dual phase steel material itself, pneumatic valve has stronger hydrogen sulfide and chlorine ion corrosion resistance. http://www。 zgbfw。 com/info/
( Fully considering the coal-water slurry medium high temperature deposition after scaling. Meet the requirements of the actual use of pneumatic valve. http://www。 zgbfw。 com/info/
( All forgings duplex stainless steel by pneumatic valve adopts fixed ball forms. Medium of the force acting on the seal a floating ball sharply lower, open-close torque decreases. Can effectively prevent spring failure caused by deposition and scaling. Sealing ring with flexible graphite or plastic alloy. Material has good sealing performance and high temperature resistance ( Flexible graphite can reach ℃, plastic alloy reached C, pneumatic valve stem precipitation hardening stainless steel.
