S500QL1 Low Alloy Structural Steel
S500QL1 is used in buildings, bridges, ships, vehicles, pressure vessels and other structures. The carbon content (smelting analysis) is generally not greater than 0.20%, the total alloy element content is generally not greater than 2.5%, the yield strength is not less than 295MPa, and has good impact Low alloy steel for toughness and weldability.

The three levels of S500Q chemical composition are as follows (element composition: wt%)
1) There is no code for the first level: S500Q: P: ≤ 0.025, S: ≤ 0.015
2) L-level code L represents S500QL: P: ≤ 0.020, S: ≤ 0.010
3) L1 level code L1 is expressed as S500QL1: P: ≤ 0.020, S: ≤ 0.010
