O1 (1.2510) is a general-purpose oil-hardening, cold work tool steel giving good durability, excellent wear resistance and dimensional stability when heat treated. Having a fine grain structure, it is easy to sharpen, so holds a keen cutting edge. O1 is relatively inexpensive, so is typically used where tool steel alloy steels cannot provide the necessary hardness, strength and wear resistance, yet where the expense of a high carbon high chromium steel cannot be justified.
Typical applications:
O1 is mainly used for short to medium run tooling for cold forming dies, blanking dies, cutting and punching tools operating at ambient temperature: press tools, thread rolling tools, punches, knock-out pins, cams, knife blades, measuring instruments , gauges, jigs, broaches, lathes, shear knives, paper & cloth cutting machine knives, precision measuring tools, woodworking tools.
AKM Tip:
Whilst O1 is a great all-round cold work tool steel, the metallurgy of tool steels is complex, so if you need any help determining the best steel for a given application, please get in touch with details of your intended usage. There may well be a new specially developed next generation tool steel that
