12KHN2 - 15CrNi6 - 15hn round, rod, forging

12KHN2 - 15CrNi6 - 15hn round, rod, forging

Supplier — Avec Glob Company — offers at a reasonable price from the manufacturer a circle, bars, forgings, which are made of 12ХН2 steel (15СrNi6, 15hn). The supplier guarantees the timely delivery of products to any address specified by the consumer.

Technical specifications

Low-carbon steel grade 12ХН2 (the nearest foreign analogues are steel 15СrNi6, 15hn) is a structural steel alloyed with chromium and nickel. Steel is characterized by a fine-grained microstructure, which is completely preserved after heat treatment, and the presence of chromium increases the heat resistance of the material. The steel is well suited for chemical-thermal treatment — carburizing and nitrocarburizing, resulting in an optimal combination of surface hardness with a more viscous core. The ductility of the steel allows it to be used in the processes of hot and cold deformation.

Urgency of application

After quenching with subsequent tempering, steel 12ХН2 (15СrNi6, 15hn) can be used for the manufacture of parts operated at average values of working loads and speeds of mutual sliding — drive conical gears, wheel hubs, cam clutches of various drives, shafts, automotive and other high-loaded fasteners. After chemical-thermal treatment, the steels in question can be used in the manufacture of parts that work at elevated values of sliding friction.

Chemical composition

According to the technical requirements of GOST 4543−91, the following elements are included in steel 12ХН2 (numerical data — in percent):
