S690QL Steel Description
690QL steel is a high strength low alloy structural steel, mainly
used in engineering projects that require high strength and good
toughness.It is a type of quenching and tempering high-strength
steel, the mechanical properties are usually improved by quenching
and tempering."690" represents its minimum yield strength of 690
MPa, and "QL" means that the steel has been tested for
low-temperature impact toughness (L stands for low temperature, and
Q stands for quenching and tempering).
S690QL is a quenched and tempered high-strength low-alloy steel, in
compliance with EN 10025:6.Its yield strength is greater than
690MPa, and it is usually used to manufacture low-temperature
resistant, high-strength key components and structural parts, such
as construction machinery, mining machinery, etc.
HSLA Steel Sheet Features
- Reduced weight of products and structures while retaining strength
- Increased payload capacity
- Increased reach capacity
- Reduced fuel usage
- Resistance to wear and corrosion
- Easy weldability and laser cutting
High-strength low-alloy steel (HSLA) is a type of alloy steel that
provides better mechanical properties or greater resistance to
corrosion than carbon steel. HSLA steels vary from other steels in
that they are not made to meet a specific chemical composition but
rather specific mechanical properties.
