Consequently JIS G However, JIS G Attention is drawn to the possibility that some parts of this Standard may conflict with a patent right, application for a patent after opening to the public, utility model right or application for registration of utility model after opening to the public which have technical properties.
The relevant Minister and the Japanese Industrial Standards Committee are not responsible for identifying the patent right, application for a patent after opening to the public, utility model right or application for registration of utility model after opening to the public which have the said technical properties. The portions with continuous sidelines or dotted underlines are the matters in which the content of the corresponding International Standard has been modified.
A list of modifications with explanations is given in Annex JA. NOTE 1 The steel sheet and strip may be de scaled by pickling or shot blasting after the hot-rolling operation on request by the purchaser.
Norma ti ve references The following standards contain provisions which, through reference in this text, constitute provisions of this Standard. The most recent editions of the standards including amendments indicated below shall be applied. Table 2 Chemical composition Unit: However, the values in table 3 shall be applied to those for delivery inspection 1.

Note 1 Steel sheets and strips may decrease the elongation by age hardening. Js following may be applied as the upper limit of tensile strength as agreed between the purchaser and the manufacturer. However, the tolerances on thickness shall be in accordance with table 4 and the measurement of edge camber shall be carried out when requested by the purchaser. G1331 this respect, tolerances on length for the steel sheet and those y3131 width for the cut-edge steel sheet shall, unless otherwise specified, be in accordance with the tolerance A of JIS G For the steel sheet and strip under 40 mm in width, measurement shall be made at the mid-width thereof.
The values specified in ijs 4 shall not be applied to the irregular portions of both ends of the steel strip. The tolerance on thickness of the steel sheet which is not manufactured from the steel strip may be agreed between the purchaser and the manufacturer. The value shall be applied to the steel sheet and strip under mm in width.
As for the squareness of cut-edge steel sheet, the following method using the diagonal line may be applied. Steel sheets and strips de scaled jos acid pickling or shot-blasting shall be oiled. Steel sheets and strips as rolled shall not be oiled. The repair by welding shall not be performed.

X If necessary, the treatment of irregular portions of steel strip may be agreed between the manufacturer and the purchaser. For steel strip and cut lengths thereof One test piece each for tensile and bend tests shall be taken from each test lot of the same heat rolled to the same thickness.
When the js of one test lot exceeds 50 t, however, two sets of test pieces shall be taken from the lot. For steel sheet excluding cut lengths thereof One test piece each for tensile and bend tests shall be v3131 from each test lot of the same heat where the maximum thickness of the steel sheet is within twice the minimum thickness thereof. Sampling position and direction of tensile test and bend test pieces The test piece shall be taken jie to the rolling direction and the centre of the test piece shall be at a quarter-width from a side edge.
When it is infeasible to allow the centre of jls test piece to be at a quarter-width from a side edge, the sampling should be performed as close to the aforementioned position as possible. The test method shall be as specified in 9. The test method shall be as specified in JIS Z The chemical composition shall conform to the requirements specified in clause 4.
The mechanical properties shall conform to the requirements specified in clause 5. The shape, dimensions and mass shall conform to the requirements specified in clause 6. The appearance shall conform to the requirements specified in clause 8. The steel sheets which are not bundled shall be marked for each sheet. In the case, the report shall be in accordance with the requirements of clause 13 in JIS G Hot-rolled mild plates, sheets and strips intended for general fabricating purposes and drawing are specified.
JIS has changed “for drawing” to “for processing”. Chemical composition of four elements C, Mn, P, S are specified. Chemical composition of Deletion four elements C, Mn, P, S and additional alloy elements are specified. V Justification for the technical deviation and future measures Tensile strength, elongation and bendability are specified. Tensile strength and elongation are specified. In JIS there is no description of the inside diameter and the maximum outside diameter of the coil.
It is required to specify the inside diameter, the maximum outside diameter and the maximum mass of the coil. The appearance is specified. Analytical test is specified.

Sam pIing frequency of the tensile test piece is specified. Tensile test method is specified.
Modification of the tensile direction will cause the confusion in the marketo This is the unique configuration to JIS. Judgement of the reinspection is specified. Marking of seven items is specified.
Identical Identical 11 Marking Marking of five items is specified. In JIS, a part of items are deleted. In JIS, the number of the standard can be replaced by the symbol of grade. The order number is a matter of contract and is deleted. In JIS, items related to quality are specified. V Justification for the technical deviation and future measures Content The report is specified. No item For addition of the specification of the report, proposal will be submitted to ISO.
Terms are defined in JIS G The products covered by this Standard are for general use and it is not required. Inspection observed by the purchaser is specified.
Inspection observed by the purchaser is deleted in JIS. Identical in technical contents. Deletes the specification item s or content s of International Standard.
