1. 10 × steel plate introduction
The steel plate of 10 × steel is a low-carbon steel plate with carbon content of about 10% (0.07-0.14), and the content of sulfur (s) and phosphorus (P) impurities is generally controlled below 0.035%.
2. 10. Executive standard of steel plate
10. The steel plate can be delivered in hot rolling or normalized state according to the customer's requirements, and the steel plate shall comply with GB / t711-2017 standard
3. 10 × steel plate composition introduction
Tensile strength ≥ 410 MPa, yield strength ≥ 205mpa, elongation δ 5 (%): ≥ 32, area shrinkage ψ (%): ≥ 55, hardness: not heat treated, ≥ 137hbs. This kind of steel must guarantee both chemical composition and mechanical properties while ensuring these requirements. We usually call it excellent carbon steel plate. 10 steel plate has good plasticity and toughness, easy to be formed by cold and hot working, good cutting performance after normalizing or cold working, good weldability, no temper brittleness, poor hardenability and hardenability.
