1 Scope

This Standard specifies the carbon steel pipes (hereafter referred to as “pipes”) used for high pressure service at temperatures 350°C or lower. This Standard is generally applicable to pipes of outside diameters 10.5mm (nominal diameter 6A or 1/8B) to 660.4 mm (nominal diameter 650A or 26B).

In addition to the items specified in this text, the purchaser can previously designate special quality requirements upon agreement with the manufacturer, which are shown in Annex JA.

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

ISO 9329-2: 1997 Seamless steel tubes for pressure purposes-Technical delivery conditions-Part 2: Unalloyed and alloyed steels with specified elevated temperature properties (MOD)

The 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/IEe Guide 21-1.

JIS G3455 Grade STS 38/42/49 Specification Covers Carbon Steel Pipes for High Pressure Service. Mechanical properties of This steel grades can be varied greatly by heat treating. Through a controlled cycle of heating and cooling, certain desired properties are obtained by producing predictable changes in the microstructure of the steel.
