20MnCr5 Carburizing Round Bar
Primary Standard: EN 10084 | Grade: 20MnCr5
1. Product Overview
20MnCr5 Carburizing Round Bar is the European (EN/DIN) standard equivalent of 20CrMnTi (GB/T 3077-2015), supplied per EN 10084. This standard is the European standard basis for EU and Middle East projects. 20CrMnTi is the classic carburizing gear steel - after carburizing and quenching it achieves high surface hardness with a tough core, making it the first choice for gear transmission parts in vehicles and construction machinery. Per GB/T 3077-2015, near-equivalent to ASTM 8620 / DIN 20MnCr5.
