High Alloy Steel Plate

4140 steel sheet,Alloy Structural Steel Plate,alloy plate,High Alloy Steel Plate The alloy steel plates sold by the company are mainly used for manufacturing bridges, ships, vehicles, boilers, high-pressure vessels, oil and gas pipelines, large steel structures, etc. The yield strength should be above 300MPa, with a required elongation of 15% to 20%, and a room temperature impact toughness greater than 600kJ/m to 800kJ/m. For large welded components, high fracture toughness, good welding and cold forming performance, and good corrosion resistance are also required.
