scope:
This Standard specifies carbon steels (hereafter referred to as "steels") for machine structural use mainly manufactured by hot forming such as hot rolling and hot forging. Steels are generally used after further processes of forging, cutting and heat treatment.
In addition, in the case of steel plates and steel strips, those cold reduced may be included according to the thickness as well as those hot rolled.
NOTE : The International Standards corresponding to this Standard and the symbol of degree of correspondence are as follows.
ISO 683-1 : 1987 Heat-treatable steels, alloy steels and free-cutting steels- Part 1: Direct-hardening unalloyed and low-alloyed wrought steel in form of different black products
ISO 683-11 : 1987 Heat-treatable steels, alloy steels and free-cutting steels-Part 11: Wrought case-hardening steels (Overall evaluation: MOD)
In addition, symbols which denote the degree of correspondence in the contents between the relevant International Standards and JIS are IDT (identical), MOD (modified), and NEQ (not equivalent) according to ISO/ IEC Guide 21.
