HSLA steels
A low alloy steel or microalloyed steel is a steel containing one or more of the alloys Nb, Ti, and V to achieve the required proof strength levels. Note: With precipitation and grain refinement hardening combined, high mechanical resistance is achieved while the alloying elements are reduced.
Specific applications of B53 3271 He490di steel include:
Body structural parts: inner door panels, roof panels, hoods, side panels, etc.
Suspension systems: suspension arms, suspension springs, shock absorber housings, etc.
Steering systems: tie rods, steering gear housings, etc.
Engine components: cylinder blocks, crankcases, connecting rods, etc.
Using B53 3271 He490di steel to manufacture automotive components can improve the strength and durability of the vehicle, while also reducing weight, improving fuel economy, and lowering emissions. As a result, this type of steel has been widely used in the automotive manufacturing industry.
