SPECIAL
The standard of HSS material is specifi ed in JIS. But there are many HSS materials which standard is not specifi ed in JIS. Recently even the kind THREAD of HSS-P is getting wider and various. Besides, SKH10, SKH53, SKH57 and their equivalents, such Hi vanadium/hi cobalt material as contains MILLS 4-12% vanadium and 8-11% cobalt is now being manufactured. Material engineering will be developed rapidly in the future. Under such situation, there can be many cases where JIS symbols are not used, and the use of larger classifi cation and their symbols is getting popular.
