FAQ
Q: What is the equivalent of S960ql?
A: What are S960ql Equivalent Astm? S960ql is a high-strength structural grade. The ASTM S960ql Equivalent is the ASTM Q345 exhibiting outstanding low temperature and cold stamping properties.
Q: What is the difference between S690Q and S690QL?
A: The Core Difference: Low-Temperature Toughness
S690Q: Minimum impact toughness tested at -20°C (30J average). → Typical Use: Cranes in temperate climates, quarry equipment. S690QL: Certified for -40°C and below (≥40J impact toughness).
Q: What is the hardness of 690ql?
A: S690QL Plates are high-strength, quenched, and tempered structural steel plates engineered for use in environments that demand high loads and heavy impacts. This steel grade is characterised by its minimum yield strength of 690 MPa, classifying it as one of the market's most robust and hardwearing steels.
