EN S420N Carbon and Low-alloy High-strength Steel

S420N carbon and low alloy high strength steel is one of the carbon steel series. S420N Carbon steel is a low alloy high strength structural steel with excellent plasticity and strength, as well as good toughness and impact value. In addition, it has good corrosion resistance, heat resistance and excellent welding performance. It can be used to manufacture heavy parts with high requirements, such as bearings, hubs, shafts, cantilever beams, bearing columns, etc.

The composition of S420N carbon high strength steel is: carbon content is 0.20-0.50%, manganese content is 0.50-1.50%, nickel content is 0.30-1.00%, vanadium content is 0.030-0.070%, zinc content is 0.030-0.070%, chromium content is 0.30-1.00%, sulfur content is 0.030-0.070%, aluminum content is 0.030-0.070%, titanium content is 0.030-0.100%.

S420N carbon and low-alloy high-strength steel has excellent mechanical properties. Its maximum tensile strength is 420MPa, yield strength is 360MPa, elongation is 22%, creep rate after fracture is 7.5%, and impact value is 27J. Therefore, it can be used to manufacture parts and structural parts requiring high strength and high plasticity, such as mechanical parts, automobile parts, bridge structural parts, building structural parts, etc.

EN S420N carbon and low alloy steel has good heat treatment performance, and can adjust the structure of the steel through normalizing and quenching, thus adjusting the mechanical properties of the steel. It also has excellent welding performance and can be used in various welding methods, such as electric arc welding, argon arc welding and tungsten clamp welding. Baibang Steel can provide S420N carbon steel of different sizes and specifications according to customer requirements, and provide processing services such as cutting, welding, bending, etc.
