Ⅰ.Application
O1 steel is one of the most well respected oil-hardening tool and mould steels.
With chromium-manganese content possessed good machinability, mechanical wear
resistance and edge holding quality. Vanadium-Wolfram content reduces high working
temperature wear and retention of temper temperature.
O1 steel is used for the majority of applications too sensitive for carbon tool steels.
Ⅱ. Melting process
EAF+LF+VD
Ⅲ. Size range
Round bars: Dia. 12mm-600mm;
Flat bars: Thickness: 16mm~300mm; Width: 155mm~800mm;
Ⅳ. Delivery condition
HR or HF, black surface or peeled/milled surface
