The elongation property of SPHC steel varies with the ranges of thickness.
jls V Justification for the technical deviation and future measures Content The report is specified. With this respects, the sampling method of specimen shall conform to Class A, and the number of test pieces and the sampling position shall be as following: Mechanical properties At the time that the steel is made available for shipment, the mechanical properties shall be as given in Annex Table 2, when they are determined on test g3113 obtained in accordance with the requirements of 6.
Hot Rolled Steel – JIS G Commercial Hot Rolled SPHC Steels
Report jsi JIS G when required by the purchaser in advance. Inspection observed by the purchaser is specified. Tolerances on thickness Thickness Width Up to and excl. Tensile test method is specified. No item For addition of the specification of the report, proposal will be submitted to ISO. The standards cited in this Standard are given in Attached Table 1. JIS C Test m Grade and symbol The steel and coil shall be classified into 3 categories, and their symbols shall be as given in Table 1.
Steel sheets and strips as rolled shall not be oiled. For steel strip and v3131 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.
Therefore we cannot say that yield and UTS are close, when steel is not absolutely brittle. For steels other than the mild steel plate, sheet and strip, ISO should be referred. X If necessary, the treatment of irregular portions of steel strip may be agreed between the manufacturer and the purchaser. Deletes the specification item s or content s of International Standard.

Hot-rolled steel sheet is suitable for many applications where the presence of oxide or scale, or normal surface imperfections disclosed after removal of oxide or scale, are not objectionable. JIS C Non-or Mechanical properties The steel sheet and coil shall be tested in accordance with 7.
Appearance The appearance of the steel sheet and coil shall conform to 6. Hi there, could you advise on the silicon content percentage of ? A part of the corresponding International Standard listed in this Standard is given in the Annex. Bending, shaping, lancing and piercing etc all are common operations that can be done on these steels. Chemical composition of Deletion four elements C, Mn, P, S and additional alloy elements are specified.
When a material grade is specified as hot rolled steel, it means it has been subjected to a manipulative process of hot rolling in which a metal bar is passed through high tension rollers above the re-crystallization temperature of the input metallic material. Mechanical property tests 6. It is not suitable for applications where surface is of prime importance.
For the steel sheet or plate up to and excluding 4 mm in thickness, the reliability of the conversion will become worse, so that jjs reliability of the conversion will become worse, so that agreement between the purchaser iis supplier is necessary when this table is applied.
The thickness shall be measured at any point on the steel sheet and coil not less than 20 mm from a side edge. The order number is a matter of contract and is deleted. A part of them is presented as given in Informative reference Table 1, accordingly.
JIS G 3131-Commercial Hot Rolled SPHC Steels
The most recent editions of the jls including amendments indicated below shall be applied. Please refer following information: The chemical composition shall conform to the requirements specified in clause 4.
Inspection observed by the purchaser is deleted in JIS. 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.
For the steel sheet and strip under 40 mm f3131 width, measurement shall be made at the mid-width thereof. 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 by acid pickling or shot-blasting shall be oiled. The shape, dimensions and mass shall conform to the requirements specified in clause 6. The test method shall be as specified in 9. For steel sheet excluding cut lengths thereof One test piece jiz for tensile and bend tests shall be taken from each test lot of the same heat where the maximum thickness of the steel sheet is within twice the minimum thickness thereof.
To minimize this effect, quality HR4 should be specified. However the width of SPHC material jia to mm. Care to your share your opinion? When the mass of one test lot exceeds 50 t, however, two sets of test pieces shall be taken from the lot.
JIS G3131 Grade SPHC commercial quality
These are also extensively used in some of the automotive manufacturing, electric products, vehicles, aviation. In JIS, items related to quality are specified. The test method shall be as specified in JIS Z The corresponding International Standard of this Standard is given in the following: It is required to specify the inside diameter, the maximum outside diameter and the maximum mass of the coil.
