Description
Jiangsu Liangyi is professional manufacturer of 20MnMoNi4-5,1.6311,20MnMoNi4.5,20MnMoNi45 open die forging parts and seamless rolled steel forged rings from china
Following is the shape of 20MnMoNi4-5,1.6311,20MnMoNi4.5,20MnMoNi45 forging steel material that we could do is:20MnMoNi4-5 Forged Steel round bars square bars Flat bars Rectangles Bars Rods,20MnMoNi4-5 Forged forging steel rings seamless rolled rings,1.6311 Forged Forging Steel Hubs housing shell Sleeves Bushes Bushing Cases Hollow Bars,1.6311 Forged Forging Steel Discs Disks Blocks plates,20MnMoNi4-5 Forged Forging Steel Pipe Tubes Tubings Piping Shells Casings Case barrels Housings.
20MnMoNi4-5 is weldable fine grained steel for higher temperature service. It is characterised by high 0.2 % proof stress at elevated temperatures. 1.6311 is produced using basic oxygen steelmaking process. Its properties are achieved by water quenching and tempering .
1.6311 is applied as plate or formed part for boilers and pressure vessels operating at temperatures of - 20 °C to 400 °C
FOllowing is production standard of 20MnMoNi4-5,1.7765 forged bars
