    This document is the Japanese Industrial Standard (JIS G 4053:2008) that specifies requirements for low-alloy steels for machine structural use. It covers various forms of low-alloy steels that are primarily manufactured through hot working processes and further heat treated or nitrided before use in machines. The standard defines 40 types of low-alloy steels and their designation codes, and includes provisions for chemical composition, dimensions and tolerances, testing methods, inspection, marking and reporting. It replaces and consolidates previous JIS standards on similar topics.

    This standard specifies requirements for low-alloyed steels that are mainly produced by hot rolling or hot forging and are intended for machine structural use.

    This standard applies to machine structural use alloy steels (hereinafter referred to as steel materials) that are mainly produced by hot rolling, hot forging, etc.

    40 types of steel materials are defined including Mn, Mn-Cr, Cr, Cr-Mo, Ni-Cr, Ni-Cr-Mo and Al-Cr-Mo steels.
