Welding s420 steel equivalent sheet chemical composition

The commonly s420 steel equivalent steels used to manufacture pressure parts of boilers mainly include low carbon steel, low alloy structural steel, low alloy heat-resistant steel, austenitic stainless heat-resistant steel and martensitic heat-resistant s

The commonly s420 steel equivalent steels used to manufacture pressure parts of boilers mainly include low carbon steel, low alloy structural steel, low alloy heat-resistant steel, austenitic stainless heat-resistant steel and martensitic heat-resistant steel, etc. According to profiles, these boiler steels can be divided into boiler steel plates and boiler steel pipes. Our main s420 steel equivalent boiler steel materials are as follows: A516 Gr 70, A537 class 1 , 16Mo3, q345r, A204 grade B, A285C, ASTM A387, P355GH and so on.

Composition of low alloy steel plate: Low carbon: due to the high requirements for toughness, weldability and cold formability of low alloy steel plate, the carbon content is not more than 0.20%; manganese is added; the auxiliary elements such as niobium, titanium or vanadium are added; a small amount of niobium, titanium or vanadium forms fine carbide or carbonitride in the steel, which is conducive to obtaining fine ferrite grains and improving the strength and toughness of low alloy steel plate; in addition, The corrosion resistance of s420 steel equivalent, low alloy steel plate can be improved by adding a small amount of copper (< 0.4%) and phosphorus (about 0.1%).

If you have any requirements for the mode of transportation of the s420 steel equivalent goods, we can also negotiate and meet your requirements. For logistics, first of all, we respect customers' opinions, and then choose the most convenient port and transportation mode with appropriate price for customers.
