2205 Stainless Steel

Duplex stainless steel 2205 Standard :ASTM A240/A240M-

-01 duplex stainless steel 2205 alloy is made of 22% chromium, 2.5% molybdenum and 4.5% nickel-nitrogen alloys

Composed of duplex stainless steel. It has high strength, good impact toughness and good performance

Overall and local resistance to stress corrosion.

Use:Pressure vessels, high pressure storage tanks, high pressure pipelines, heat exchangers, oil and gas pipelines, heat exchangers fittings

Technology:Surface treatment, welding, laser cutting, slitting

Surface:NO1, 2B, 8K

Chemical composition :C≤ 0.030Mn ≤ 2.00Si ≤ 1.00p ≤ 0.030S ≤ 0.020Cr 22.0~ 23.0Ni 4.5~ 6.5Mo3.0 ~ 3.5N0.14 ~0.20(Austenitic ferritic type)

2205 stainless steel plate is divided into cold rolled plate and hot rolled plate. Regular size thickness: 0.5 mm to 40.0 mm, width: 1000 mm, 1219 mm, 1500180 mm, 2000 mm, etc. Length: If the length of the coil can be cut according to the needs of the user, the general cold rolling is 2000mm or 2438mm, and the hot rolling is 6000mm.

cold rolled plate and hot rolled plate difference

1. Surface color difference

cold rolled plate surface is bright or silver white, the surface is smooth;

hot rolled plate surface color is relatively deep, mostly brown, and the surface is relatively rough, not as smooth as the cold plate.

The difference between specifications and sizes

cold rolled plate size generally 1000*2000mm, 1219*2438mm, 1500*3000mm commonly used plate, thickness 0.5-6mm;

hot rolled plate size is generally 1500*6000mm, 1800*6000mm, 2000*6000mm, 2000*8000 conventional size, thickness 3-40mm.
