Will weldability of nm400 plate prices be consolidated

The alloying elements of low alloy steel are less than 5%. The low alloy steel is added one or several alloy elements on the basis of carbon steel to improve the performance. Such as manganese, silicon, aluminum, nickel, copper, boron, phosphorus, rare earth, etc. weldability of NM400 plate Steel with one or more of these elements will have the advantages of high strength and toughness. Due to the addition of few alloy elements, it is called low alloy high strength steel.

Difference between Q345R boiler vessel plate and ordinary Q345 plate, weldability of NM400 plate:Q345R boiler vessel plate is pressure vessel steel, Q345 plate is low alloy steel.Q345R boiler vessel plate generally requires flaw detection and positive deviation, while Q345 plate generally has lower requirements.In terms of performance, Q345R boiler vessel plate and Q345 plate are of the same level. However, due to high requirements, they can not be mixed in general.Generally, the requirement of Q345R boiler vessel plate is higher than Q345 plate, weldability of NM400 plate.

S355NC steel offers excellent bending, flanging, cold-bordering and folding weldability of NM400 plate properties in both longitudinal and transverse direction. The bending radii specified below should be observed as minimum values.
