1560 to 1566 High Carbon Steel

A high carbon steel with substantial manganese to create a deep-hardening, strong steel when tempered. 

Primarily used by Hanwei this high carbon steel has around 0.60 – 0.70 carbon content with a substantial amount of additional manganese (0.85 – 1.15) – this combination creates a deep-hardening steel due to its high degree of hardenability. When tempered it will have a largely uniform hardened microstructure which creates a blade both hard, tough and well-suited to holding a sharp edge in extended use.
