The thickness shall be measured at any point on the steel sheet and coil not less than 20 mm from a side edge. In JIS there is no description of the inside diameter and the maximum outside diameter of the coil. The portions with continuous sidelines or dotted underlines are the matters in which the content of the corresponding International Standard has been modified. JIS C Test m The mechanical properties shall conform to the requirements specified in clause 5.

The steel sheets which are not bundled shall be marked for each sheet.

Tensile test method is specified. I want know Raw material price per Kg below mention details 1.

JIS G 3131 – 2010

The steel sheets which are not bundled shall be marked for each sheet. Transverse test piece shall be taken midway between the center and edge of the sheet as rolled. The appearance shall conform to the requirements specified in clause 8. Hot-rolled g31311 3 mm and over is thickness in commonly known as either “sheet” or “plate”.


Shape, dimensions, mass and tolerances The shape, dimensions, jiw and their tolerances of the steel and coil shall conform to JIS G With this, g313, tolerances on length for the steel sheet and those on width for the cut edged steel sheet shall, unless otherwise specified, be in accordance with the tolerance A, and tolerances on gg3131 for the steel sheet and coil shall be as specified in Table 4.

This Annex may be jiz instead of the requirements specified in 1. Modification of the tensile direction will cause the confusion in the marketo This is the unique configuration to JIS. When the mass of one test lot exceeds 50 t, however, two sets of test piece shall be taken from the lot.

Steel sheets and strips de scaled by acid pickling or shot-blasting shall be oiled. 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.


A list of modifications with explanations is given in Annex JA. The relationship between each elongation value and the conversion factor is as follows: Consequently JIS G It is not suitable for applications where surface is of prime importance. Adds the specification item g131 or content s which are not included in International Standard.

The steel sheet and coil from which the scale has been removed after the hot-rolling operation by picking or grit blasting may be shipped on request by the purchaser. A lot consists of all sheet of the same designation rolled to the same thickness and condition. V Justification for the technical deviation and future measures Tensile strength, elongation and bendability are specified. Grade and symbol The steel and coil shall be classified into 3 categories, and their symbols shall be as given in Table 1.

When it is infeasible to alloy the center of the test piece to be at a quarter-width from a side edge, however, the sampling should be performed as close to the aforementioned position as possible. For steels other than the mild steel plate, sheet and ijs, ISO should be referred. Please read article completely. Marking The steel sheet and coil having passed the inspection shall be marked with the following details for each bundle by suitable means.

Maximum percentage of Carbon C is 0.

Note 1 Hot-Rolled sheet up to but not including 3 mm in thickness is commonly known as “sheet”. It is from 1. Mechanical properties The steel sheet and coil shall be tested in accordance with 7. With this respects, the sampling method of jiw shall conform to Class A, and the number of test pieces and the sampling position shall be as following:
