BS 4659, for Tool and Die Steels - Otai Special Steel

BS 4659 specification is one British Standard which is mainly for Tool and die steels. BS 4659 specifies chemical composition, tolerances on dimensions and maximum depths of functional decarburization and recommends heat treatment temperature ranges for tool steel and die steels. Similar to DIN ISO 4957 and ASTM A681, this standard BS 4659 is also widely used for almost all kinds BS 4659:1971 - Specification for tool steelsBS ISO 16143-1:2014 Stainless steels for general purposes.
