| Tool Steels depart somewhat from the AISI to UNS conversion scheme. AISI designates many tool steels with a combination of letters and numbers and UNS allows only one letter... the first one. For example, oil hardened tool steel is designated O1 or O2 and so on. Water hardened is W1, W2 and so on. High Speed Steel can be T10 and T15 and so forth. The UNS scheme has no letter system easily correlating and identifying all of these as tool steels. So the basic UNS system for some of the tool steel types is: | ||||||||||
