Automobile manufacturers have started using ultra high strength steel (UHSS) in lower thicknness to reduce the weight of their car and improved passenger safety. As a result steel manufacturers are facing continuous challenges to develop Ultra high strength steels (UHSS) in lower thicknesses with suitable formability. In line with this, Indian steel manufacturers has also started developing different UHSS which includes hot rolled DP540/DP590/DP780/SPF590 etc. for automotive wheel rim applcation and S500MC/S650MC for automotive log and cross member application. ALM650 is one such UHSS grade recently developed whose yield strength (YS) requirement is >650 MPa, tensile strength (UTS) requirement is >700 MPa and total elongation >14%. This newly developed UHSS, conforms to the specification of S650MC as per EN-10149-2.
