A high strength steel product and a process for producing a high strength steel product, the high strength steel product being useful for producing frame components for vehicles and automobiles.

High strength steel product and a process to produce a high strength steel product

A process for producing hot-rolled steel strip with a tensile strength of between 760 and 940 MPa and a steel produced therewith, suitable for producing parts by working such as press forming, bending or stretch flanging.

Process for producing hot-rolled steel strip

A dual phase or complex phase steel strip showing no tigerstripes. The steel strip having an ultimate tensile strength Rm classifying for 1000 MPa steel category, includes (in mass percent) C 0.09-0.19%; Mn 1.9-2.6%; Si at most 0.1%; Cr 0.4-0.8%; Mo at most 0.3%; Ni at most 0.4%; Al 0.02-1.3%; and optionally one or more of the following elements: Nb at most 0.08%; P equal to or more than 0.0005%; N equal to or less than 0.015%; Ti equal to or less than 0.1%; V equal to or less than 0.1%; B equal to or less than 0.01%; wherein the sum of Cr, Mo and Ni is at least 0.5%; the balance being Fe and inevitable impurities.

Steel strip having a low Si content

A dual phase or complex phase steel strip showing no tigerstripes. The steel strip includes, in mass percent, the following elements: C 0.08-0.11%; Mn 1.70-2.20%; Si at most 0.1%; Cr 0.40-0.70%; Mo at most 0.3%; Ni at most 1.0%, Al 0.01-1.50%; Nb at most 0.07%; P equal to or more than 0.005%; N equal to or less than 0.015%; Ti equal to or less than 0.1%; V equal to or less than 0.1%; B equal to or less than 0.01%; wherein the sum of Cr, Mo and Ni is at least 0.5%; the balance being Fe and inevitable impurities.
