Structural steels with specified hardenability bands
This Standard specifies requirements for steels mainly intended for machine structural use with specified hardenability bands which are manufactured by hot-rolling, hot-forging and hot-extruding. This Standard applies to steel products with a uniform cross-section, which are generally supplied for use after further processes such as forging and cutting, and heat treatment. This Standard is not applicable to steel tubes.
