Reasons For Using HSLA Steel

Reason for Using HSLA

:HSLA steels contain additions such as zirconium, calcium, or rare-earth elements for sulfide-inclusion shape control.

: Additions of elements such as copper, silicon, nickel, chromium, and phosphorus can improve atmospheric corrosion resistance of these alloys

: Grades known as "improved-formability" HSLA steels (sheet-steel grades designated ASTM A715, and plates designated ASTM A656) have yield strengths up to 80,000 psi, yet cost only about 24% more than a typical 34,000-psi plain-carbon steel

: High-strength low-alloy (HSLA) steel is a type of alloy steel that provides better mechanical properties or greater resistance to corrosion than carbon steel

: HSLA steels are usually 20 to 30% lighter than a carbon steel with the same strength.

: HSLA steels are also more resistant to rust than most carbon steels, due to their lack of pearlite – the fine layers of ferrite (almost pure iron) and cementite in pearlite
