• HSS: Rephosphorized &<br />
HSLA steels. VCC “standard<br />
qualities for high strength<br />
material. Slightly better<br />
formability with Rephos.<br />
• HSS/EHSS: Dual phase<br />
steels, used for re<strong>in</strong>forcements.<br />
• UHSS: Boron steel. Used for<br />
re<strong>in</strong>forcements subjected to<br />
extreme load cases.<br />
