High quality pipeline steel plate is the key material for ERW line pipe, LSAW line pipe and P295GH steel hardness SSAW line pipe. It is widely used in oil, natural gas and water transportation pipeline construction, and can be used for manufacturing pressure fluid transportation construction.

p295gh steel hardness, S355j2g3 steel plate is a kind of main atmospheric corrosion-resistant steel, s355j2g1w steel plate is a kind of weathering structural steel, its mechanical properties are similar to s355j2g2. By adding CR, Cu and Ni, the oxide layer is firmly attached to the workpiece surface. This oxide layer prevents further corrosion of the steel.

Cold rolled p295gh steel hardness steel sheet can be produced by two high mill, four high reversing mill, multi high reversing mill and tandem cold mill. Although there are still only two work rolls in four high and multi high rolling mills, each work roll is supported by one or more large diameter backup rolls, which can prevent deflection of work roll. As a result, wide and thinner p295gh steel hardness steel plates can be produced. For example, 20 high mill can produce as thin as 0. 001 mm sheet, but the two high mill can only produce as thin as 0. 35mm sheet
