Organization: JSA
Publication Date: 21 November 2016
Status: active
Page Count: 27
ICS Code (Heat-treatable steels): 77.140.10
scope:

This Standard specifies carbon steels for machine structural use (hereafter referred to as steel products) 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 of forging, cutting and heat treatment. This Standard is not applicable to steel tubes 1).

The manufacturing method and quality requirements for hot-extruded sections are given in Annex JA.

NOTE: The International Standards corresponding to this Standard and the symbol of degree of correspondence are as follows.

ISO 683-1: 2012 Heat-treatable steels, alloy steels and free-cutting steelsPart 1: Non-alloy steels for quenching and tempering

ISO 683-3: 2014 Heat-treatable steels, alloy steels and free-cutting steelsPart 3: Case-hardening steels (overall evaluation: MOD)

In addition, symbols which denote the degree of correspondence in the contents between the relevant International Standard and JIS are IDT (identical), MOD (modified), and NEQ (not equivalent) according to ISO/ IEC Guide 21-1.

Note 1) Steel tubes are covered in JIS G 3478 (carbon steel tubes for general machine structural purposes )
