Product Description
Q420A SEV295 S420NL/1.8912 Carbon Steel Bar
1: Q420A Steel Introduction
Q420A is a kind of steel used to make high strength structural parts, the main components are carbon, silicon, manganese, sulfur, phosphorus and other elements, of which the carbon content is about 0.20% or so. The material, after appropriate heat treatment and rolling, has high strength and good plasticity, as well as high yield strength and ultimate strength, with yield strength reaching more than 420MPa and ultimate strength reaching more than 550MPa.

7: Q420A Steel Application
Q420A is used in aviation, automotive, rail transportation and marine engineering. In aeronautical engineering, the material can be used to manufacture parts such as fuselage, engine and landing gear, which has the advantage of improving the safety and economy of aircraft. In automotive engineering, the material can be used to create more durable and safer body and chassis structures. In rail transportation engineering, the material can be used to manufacture components such as bodies and wheels for high-speed trains. In marine engineering, the material can be used to manufacture offshore wind towers, ship hulls, submarine pipelines and other structures with good resistance to seawater corrosion and weathering.
