Abstract Several groups of cold-rolled, high-strength sheet steels have been developed to optimize the required strength and formability levels for automotive applications. Multiphase steels offer new opportunities where high-strength levels are demanded.
This study presents a comprehensive finite element (FE) analysis of cold-formed high strength steel (CFHSS) tubular T-joints. The brace members of tubular T-joints were made up of rectangular (including square) and circular hollow sections (RHS and CHS), whereas the Heating Helps Forming, Part 1:Hot Stamping of High Jul 29, 2020 · With electrification (plug-in hybrid or battery-electric vehicle), lightweighting has become increasingly important. Although third-generation cold-formable advanced high-strength steels (AHSS) seem to challenge PHS grades in some applications, in most cases PHS still offers better formability in the press shop, and higher strength after quenching.

enhance strength, toughness, formability, and weldability Acicular ferrite (low-carbon bainite) steels,which are low-carbon (less than 0.05% C) steels with an excellent combination of high yield strengths, (as high as 690 MPa, or 100 ksi) weldability, formability, and good toughness Dual-phase steels,which have a microstructure of martensite dis- High-strength low-iron-loss silicon steels fabricated by Mar 15, 2019 · High strength non-oriented thin gauge silicon steel (HST)with a thickness of 0.20 and 0.15 mm and a yield strength of more than 570 MPa and 780 MPa was developed by Nippon Steel by employing P, Mn, and Ni as solid solution-strengthening elements . These elements can increase strength with less deterioration of magnetic properties; however, the addition of expensive metallic Ni

Welding trials were conducted to assess the weldability of a range of 8 grades of high strength steels with thicknesses in the range 0.65-1.2mm. It has been established that, with the exception of one solid solution hardened and one dual phase steel, which had the higher alloy contents, 5 root t diameter welds could be produced using the Rolled Steel Cold Rolled Steel Grades CRC Steel CR Cold rolled HSLA (High Strength Low Alloy) steels are strengthened by a combination of precipitation hardening and grain size refining resulting in high strength with low alloy. Due to their fine grain microstructure and excellent weldability these grades are particularly suitable for structural components such as suspension systems and chassis and reinforcement parts.
Mar 31, 2021 · Advanced high strength steels (AHSSs) for auto-making are primarily produced by rolling, plus heat treatment technologies if necessary. However, due to the metallurgical complexity of AHSSs, it is impossible to roll all of the AHSS grades in a rolling mill with the same rolling technology. Each of AHSSs has unique applications in vehicles, and specified rolling technologies are required to Strenx 700 CR - High-strength, cold-rolled steel - SSABThe high-strength structural steel at 700 MPa Strenx® 700 CR is a cold-rolled structural steel with a minimum yield strength of 700 MPa used to produce stronger and lighter structures. Strenx ® 700 CR comes in cut-to-length sheets. Typical applications include a wide range of components and parts, for example load-bearing structures.
