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.

generaly pressure vessels should withstand internal and external pressures in the form of static or periodic stresses. if the application of such a vessel requires the lowest possible weight, the fracture mechanics approach may be considened in design procedure in order to obtain the minimum wall thickness. in this work the thickness of the vessel wall was determined using k values and smallest...

key account business analyst, Quaker Chemical Corp., Conshohocken, Pa., USA [email protected] Nucor Steel Tuscaloosa Inc. is the first U.S. mill to employ Steckel mill technology for producing high-quality wide coiled plates and discrete plates. Since 1985, the Steckel mill has consistently demonstrated product versatility, quality and cost advantage over traditional plate mills. The single...

Through the pseudo-static test on the steel truss coupling beams with buckling-restrained brace, the bearing capacity, deformation capacity, hysteresis curve, skeleton curve, ductility, Energy Dissipation and stiffness degradation of such coupling beam are understood. The test results show that the steel truss coupling beams with buckling-restrained brace is characterized by bigger bearing capa...

Abstract S500MC steel is a grade of high-strength low-alloy (HSLA) which widely used in the automotive industry and for agricultural machinery equipment. Considering properties this alloy, selection welding process parameters becomes essential to ensure that HSLA assemblies meet specific service requirements. In work, mechanical metallurgical produced by autogenous laser beam (LBW) automatic ga...
