S690QL steel is a high strength, low alloy structural steel that has been designed for use in heavy-duty applications such as cranes, bridges, and other structures. This steel grade is also known as Quenched and Tempered Steel, which refers to its heat treatment process.
S690QL steel is a high yield strength steel with a minimum yield strength of 690 MPa. It has excellent weldability, formability, and toughness, which makes it suitable for use in a variety of heavy-duty applications. This steel grade is also known for its high resistance to fatigue and abrasion.
Benefits of S690QL:
- High Strength: S690QL steel has a high yield strength of 690 MPa, which makes it suitable for use in heavy-duty applications that require high strength and durability.
- Good Weldability: S690QL steel has excellent weldability, which makes it easy to fabricate and assemble.
- Toughness: S690QL steel has good toughness, which provides resistance to impact and fatigue, making it suitable for use in heavy-duty applications.
- Corrosion Resistance: S690QL steel has good corrosion resistance, which makes it suitable for use in offshore structures and other applications where exposure to harsh environments is expected.
Out of all quenched and tempered graded materials, S690QL is Masteels most popular grade. Masteel stock and supply S690QL material in thicknesses up to 250 mm.
From stock, Masteel offer S690QL in plate and profiles. Profiles are produced in house by our gas and plasma cutting machines. All stock material is sourced from the most reputable European steel mills, complete with full traceability and 3.1 material certs.
