S690QL high-strength structural steel plate is a steel plate with high strength, high ductility and high impact resistance. It is heat treated by quenching and tempering process and has good welding and bending properties.
S690QL Technical details
S - is for Structural Steel
690 - is for minimum yield strength (MPa)
Q - is for Quenching & Tempering and
L - is for low attain toughness testing temperature
