Mechanical properties as well crack resistance and stress corrosion cracking (SCC) parameters of ultralow-carbon martensite steels (ULMS) type 05H2G2B HSLA pipe steel 10G2FB with a different structures depending on processing are investigated. It is shown that despite higher strength level, SCC ULMS 25–30% than for ferrite-perlite structure close to this subjected quenching tempering.

Like all steel types, HSLA requires a definition and strict practical adherence to welding parameters in order to achieve the required weld quality. Different sources offer a varying array of welding parameters. Although their hierarchical importance can be disputed, their principal definition and practical adherence are prerequisites for the quality of welded joints 1,2 . The analysis of earli...

modern vehicle bodies make intensive use of high strength steel grades to meet the contradicting demand of lighter weight and simultaneously better mechanical performance. for many steel grades microalloying by niobium is the key to achieve their characteristic property profile. in hsla steels niobium enhances the strength primarily by grain refinement. in interstitial free high strength steels...
