High-Strength Low-Alloy Steels - ASM International

The chemical composition of a specific HSLA steel may vary for different product thicknesses to meet mechanical property requirements. The HSLA steels in sheet or plate form have low carbon content (0.05 to −0.25% C) in order to produce adequate formability and weldability, and High-Strength Low-Alloy Steels / 195

Cold Rolled Steel Sheet Cold Rolled Steel Plate

Cold rolled steel sheet is, essentially, hot rolled steel that has been further processed to increase its strength and strength-to-weight ratio. In general, cold rolled steel sheet can hold tighter tolerances than hot rolled when machined or otherwise fabricated, and provides a better overall surface finish.

Corrosion uncertainty modelling for steel structures

Low alloy steels are also used, mainly for the weight savings achievable by their higher structural strength. However, the corrosion behaviour is similar to mild steel (see below) and hence corrosion is a more critical issue. Paint coatings and cathodic protection are the main means employed to protect steel against corrosion.
