Low alloy structural steel (also known as ordinary low alloy steel,
HSLA)
1. It is mainly used in the manufacture of Bridges, ships,
vehicles, boilers, high-pressure vessels, oil and gas pipelines,
large steel structures, etc.
2. Performance requirements (1) High strength: generally, its yield
strength is above 300MPa.
(2) High toughness: elongation is required to be 15% ~ 20%, room
temperature impact toughness is greater than 600kJ/m ~ 800kJ/m.
High fracture toughness is also required for large welded
components.
(3) Good welding performance and cold forming performance.
(4) low brittle transition temperature.
(5) Good corrosion resistance.
3. Composition characteristics (1) Low carbon: due to high
requirements of toughness, weldability and cold forming
performance, its carbon content is not more than 0.20%.
(2) add alloy elements dominated by manganese.
(3) the addition of niobium, titanium or vanadium and other
auxiliary elements: a small amount of niobium, titanium or vanadium
in the steel to form fine carbide or carbonitride, is conducive to
obtain fine ferrite grains and improve the strength and toughness
of steel. In addition, adding a small amount of copper (≤0.4%) and
phosphorus (about 0.1%) can improve the corrosion resistance.
Adding a small amount of rare earth elements can desulfurize,
degassing, purify steel, improve toughness and process properties.,
