| description | A press hardened steel part having a composition including, by weight percent: C 0.2-0.34%, Mn 0.50-1.24%, Si 0.5-2%, P≤0.020%, S≤0.010%, N≤0.010%, and including optionally one or more of the following elements: Al: ≤0.2%, Cr≤0.8%, Nb≤0.06%, Ti≤0.06%, B≤0.005%, Mo≤0.35% the remainder of the composition being iron and unavoidable impurities resulting from the smelting. The press hardened steel part has a microstructure including, in surface fraction, 95% or more of tempered martensite and 5% or less of bainite, austenite or ferrite. |
