Hot rolled S690QL chemical composition chemical composition

Mo alloy boiler steel plate S690QL chemical composition is mainly used for building pressure vessels.The minimum yield strength of SB480M shall be above 275Mpa, and tensile strength of SB480M shall be within 480-620Mpa. For boiler steel plate SB480M with thickness exceeding 38mm shall be normalized when rolling,and belows or equal to 38mm thickness, as rolled is ok. Besides, ultrasonic test is necessary,and high tension, simulated post welded heat treatment shall be chosen by the end users.

S690QL chemical composition, High-strength wear-resistant plates have outstanding performance advantages. First of all, the high-strength wear-resistant plates get their name because their wear resistance is very good, and the degree of wear will not be prominent. Secondly, the corrosion resistance of the high-strength wear-resistant plate is very good. General chemical plants have many corrosive liquids, and the high-strength wear-resistant plates can be used as the floor to reduce risk of accidents.
