JIS G3124 outlines the requirements for high-strength steel plates intended for use in boilers and pressure vessels subjected to intermediate and moderate temperature services. Classified as High-Strength Low-Alloy (HSLA) steel, it exhibits excellent strength characteristics. Mechanical properties define three grades under this specification: SEV245, SEV295, SEV345. CG Steel, a proficient supplier of boiler and pressure steel plates, is capable of providing JIS G3124 steel plates and coils across all grades and dimensional specifications.
