ASI - High-strength steel

Contemporary high-strength Q&T steels are all generally considered low- to medium-alloy content steels, exhibiting high strength and hardness, coupled with good formability and weldability. They also maintain exceptionally low temperature notch toughness and crack propagation resistance despite the high strength levels involved. Advanced High-Strength Steel (AHSS) Definitions Advanced High-Strength Steels (AHSS) are complex, sophisticated materials, with carefully selected chemical compositions and multiphase microstructures resulting from precisely controlled heating and cooling processes. Various strengthening mechanisms are employed to achieve a range of strength, ductility, toughness, and fatigue properties.

WELDING HIGH STRENGTH STEELS Fabricating and

If a welder is welding high strength steels to each other, then typically the filler metal will match the yield strength of the two. For example, welding high strength steel with 100 ksi yield strength to itself would require a filler metal that offers a minimum of 90 ksi tensile strength (and a maximum of 120 to 130 ksi). High Strength Steel - an overview ScienceDirect TopicsStructural or constructional steels are mild steel types; within this category the term high strength denotes the use of C:Mn steels (including microalloyed and weather-resistant steels), rather than any form of alloy steel.
