This Standard specifies the hot-rolled nickel steel plates (hereafter referred to as "steel plates") to be used for pressure vessels and storage equipment for low temperature service.
NOTE: The International Standards corresponding to this Standard and the symbol of degree of correspondence are as follows.
ISO 9328-1 : 2011 Steel flat products for pressure purposes - Technical delivery conditions - Part 1 : General requirements
ISO 9328-4 : 2011 Steel flat products for pressure purposes - Technical delivery conditions - Part 4 : Nickel-alloy steels with specified low temperature properties (Overall evaluation: 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/lEC Guide 21-1.
