Audited Supplier GB/T 3077 is the Chinese standard for alloy structural steel used in engineering and mechanical parts, of which 12crmo, 15CrMo, 35CrMo, 42CrMo, 12cr1MOV are the most popular grades.This type of steel grades offers superior wear resistance in comparison to steel grades with lower carbon content. The mechanical engineering industry widely employs GB/T 3077 alloy steel plate for the production of high-strength parts such as compressors, turbines, working elements for heavy ground and underground equipment, as well as parts for agricultural machinery.
1. GB/T 3077 alloy steel plate series involves subjecting it to quenching and tempering, thereby increasing its through-hardening capabilities.
2. This variety of alloy steel plate exhibits remarkable features such as high strength and hardenability, good toughness, small deformation while undergoing quenching, high creep strength and long-lasting strength at elevated temperature.
