Foreword
This translation has been made based on the original Japanese Industrial Standard re-
vised by the Minister of Economy, Trade and Industry through deliberations at the
Japanese Industrial Standards Committee as the result of proposal for revision of
Japanese Industrial Standard submitted by Japan Stainless Steel Association (JSSA)
/Japanese Standards Association (JSA) with the draft being attached, based on the pro-
vision of Article 12 Clause 1 of the Industrial Standardization Law applicable to the
case of revision by the provision of Article 14.
Consequently JIS G 4305:2010 is replaced with this Standard.
However, JIS G 4305:2010 may be applied in the JIS mark certification based on the
relevant provisions of Article 19 Clause 1, etc. of the Industrial Standardization Law
until September 19th, 2013.

Being in conformance with this Standard may come under the use of the patent rights
held by the following.

JAPANESE INDUSTRIAL STANDARD JIS G 4305 : 2012
Cold-rolled stainless steel plate, sheet and strip
Introduction
This Japanese Industrial Standard has been prepared based on the first edition of
ISO 16143-1 published in 2004 and the first editions of ISO 9445-1 and ISO 9445-2
published in 2009 with some modifications of the technical contents.
The portions given continuous sidelines are the matters in which the contents of the
corresponding International Standards have been modified. A list of modifications with
explanations is given in Annex JB.
1 Scope
This Standard specifies the cold -rolled stainless steel plates and sheets (hereafter
referred to as "plates") and cold-rolled stainless steel strip (hereafter referred to as
"strip").
NOTE: The International Standards corresponding to this Standard and the
symbol of degree of correspondence are as follows:
ISO 16143-1 : 2004 Stainless steels for general purposes - Part 1 : Flat
products
ISO 9445-1 : 2009 Continuously cold-rolled stainless steel- Tolerances
on dimensions and form - Part 1 : Narrow strip and cut lengths
on dimensions and form - Part 2 : VVide strip and sheetlplate (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 ISOIIEC Guide
21-1.
2 Normative references
The following standards contain provisions which, through reference in this text,
constitute provisions of this Standard. The most recent editions of the standards (in-
cluding amendments) indicated below shall be applied.

Notes a) When it is required that the designation indicates that the product is plates, the
symbol - CP shall be suffixed to the designation of grade.
Example SUS304 - CP
b) When it is required that the designation indicates that the product is strip, the
symbol - CS shall be suffixed to the designation of grade.
Example SUS304 - CS
4 Manufacturing method
The manufacturing method shall be as follows.
a) Plates and strip shall be heat treated after cold-rolling and given acid pickling or
an equivalent treatment. As required, levelling, grinding, temper rolling or a com-
bination of these treatments may be performed. For plates and strip given bright
heat treatment, however, treatments such as acid pickling may be omitted upon
agreement between the purchaser and the manufacturer.
NOTE: Representative heat treatment conditions are shown in Annex JA for
reference. Other conditions than given in the Annex can be applied.
b) For plates or strip of SUS420J2 and SUS440A, if especially designated by the pur-
chaser, quenching and tempering may be performed. In this case, symbol Q shall be
attached to the designation.
c) For plates or strip of SUS630 and SUS631, the purchaser shall designate either the
solution treatment or precipitation hardening treatment. In this case, a symbol in-
dicating the type of heat treatment given in table 2 shall be attached to the desig-
nation.

5 Chemical composition
5.1 Heat analysis values
Plates and strip shall be tested in accordance with 11.1, and the obtained heat analy-
sis values shall satisfy the requirements in table 3 to table 7.
5.2 Product analysis values
If the purchaser requests a product analysis, plates and strip shall be tested in ac-
4
G 4305 : 2012
cordance with 11.1, and the test results shall satisfy the requirements in table 3 to ta-
ble 7 within the tolerances given in table 5 of JIS G 0321. However, the tolerances for

The appearance shall be as follows.
a) Plates and strip shall be free from defects detrimental to practical use. However,
strips are permitted to have a minor amount of defects since they are generally
