Automotive High Strength Steel (AHSS) are steels with a multiphase microstructure that contains one or more phases in sufficient amounts to produce distinctive mechanical properties, such as martensite, bainite, austenite, and/or retained austenite.
Some varieties of AHSS have a better strain hardening capacity than typical steels, resulting in a superior strength-ductility balance. Other varieties have extremely high yield and tensile strengths, as well as bake hardening properties.
The Global Automotive High Strength Steel Market accounted for $XX Billion in 2021 and is anticipated to reach $XX Billion by 2026, registering a CAGR of XX% from 2022 to 2027.
JFE Steel Corporation and thyssenkrupp Steel Europe (tkSE), Germany’s largest steel producer, announced the launch of new high-strength steel sheets capable of cold forming for the fabrication of vehicle frame components in the 980- and 1180MPa classes.
When compared to standard high-tensile steel sheets, the products attain higher yield strength and ductility, particularly superior local ductility, resulting in lighter-weight automotive body frames (“body in white”) and improved crash safety performance.
The Ram exhibit at the North American International Auto Show includes an interactive steel installation. The display was created in partnership with Ram by the Steel Market Development Institute (SMDI), a commercial unit of the American Iron and Steel Institute (AISI). In the cab and frame of the all-new 2019 Ram 1500, high-strength steel is used extensively.
According to Ram, this is the strongest 1500 yet, with a frame made of more than 98 percent high-strength steel and a core body structure made of 54 percent high-strength steel. Noise, vibration, and harshness (NVH) reduction measures, weight reductions of roughly 225 pounds, and increased rigidity for improved handling and longevity are all possible thanks to the use of high-strength steel in the frame.
