Quality Carbon Structural Steel

10-324-03

Quality carbon structural steel refers to steel with carbon less than 0.9%, in which the carbon more than 0.6% are named as high carbon steel.
There are two types of high carbon steel, one, with normal Mn content is called normal carbon steel, the other with carbon 0.7% - 1.2% Mn is called Manganese carbon steel.

Standard：GB/T 699, SAE-J403
Main application：After heat treatment as annealing, tempering, hardening, the hardness of the carbon steel will greatly be improved, as well as its flexibility, especially steels with high manganese content. With these properties, high carbon steel can be used to produce spring, spiral spring, steel wire and rope, mill roller, blade saw, etc.
