with good machining performance excellent polishing performance and hardenability, high hardness and weatr resistance, at the same time the cross-section of a larger size will enable a more uniform hardness
- Delivery condition
Hot rolling or forging, black surface, pre-harden or tempering to 28~33HRC/30~35HRC Width:1500~2500mmï¼ÂŒThickness:20~410mm
-
General
Through-hardening, good machining and mirror polishing abilities; in hardened condition, mold cavity can be put in direct use after processing; suitable for surface treatment and chrome plating; nitriding can increase surface hardness - Chemical analysis
