Premium quality 16MnCr5 carbon steel bars for applications requiring excellent toughness, wear resistance, and surface hardenability. Available in round, square, and flat bar forms
PRODUCT SPECIFICATION
16MnCr5 carbon steel bars are low-alloy case hardening steels, widely used in engineering and mechanical components where high surface hardness and core toughness are required. The steel grade 16MnCr5 (1.7131) offers a good balance of machinability, strength, and wear resistance after heat treatment processes such as carburizing and quenching.
These bars are manufactured to strict dimensional tolerances and surface finish standards, available in various shapes including round bars, flat bars, and square bars. They comply with EN 10084 standards and are ideal for further machining, forging, or hardening.
