S420N High Strength Structural Plate
S420N HSLA Steel Plate Products Description
S420N alloy steel plate is a European standard low alloy high strength steel plate with good resistance to atmospheric and seawater corrosion. S420N high strength alloy steel has strong weldability and good welding performance, and can be connected by a variety of welding methods.
S420N high tensile steel engineering application areas: widely used in the production and manufacturing of large welded structural parts such as mining machinery, construction machinery, wind power equipment, large ships, bridges, power station equipment, medium and high pressure boilers, high pressure vessels, locomotives, lifting machinery, etc.
The S420N low alloy steel plate we provide has a variety of sizes and can also be customized according to specific requirements. At the same time, we can also provide the quality certificate of S420N low alloy structural steel and accept third-party testing.
