FORMABLE LIGHTWEIGHT STEEL WITH IMPROVED MECHANICAL PROPERTIES AND METHOD FOR PRODUCING SEMI-FINISHED PRODUCTS FROM SAID STEEL |
摘要 |
The invention relates to a formable lightweight steel having improved mechanical properties and high resistance to delayed hydrogen-induced cracking and hydrogen embrittlement, comprising the following elements (in wt.%): C 0.02 to ≤1.0; Mn 3 to 30; Si ≤4; P max. 0.1; S max. 0.1; N max. 0.03; Sb 0.003 to 0.8, particularly advantageously to 0.5, as well as at least one or more of the following carbide-forming elements in the specified proportions (in wt.%): Al ≤15; Cr >0.1 to 8; Mo 0.05 to 2; Ti 0.01 to 2; V 0.005 to 1; Nb 0.00 to 1; W 0.005 to 1; Zr 0.001 to 0.3; with the remainder consisting of iron including the usual steel-accompanying elements, with the optional addition of the following elements in wt.%: Ni max. 5, Co max. 10, Ca max. 0.005, B max. 0.01 and Cu 0.05 to 2. The invention also relates to a method for producing said lightweight steel. |
