In JIS, provisions for hardness test, bend test and plastic strain ratio deter- mination are added.
The depth of flaws shall conform to table 6 for killed steel including aluminum-killed steen. Tensile test method jjis specified. Tensile strain hardening ex- ponent is used rarely for cold-reduced carbon steel sheet.
I Hardness of the standard temper grade and as-annealed grade Hardness of the standard temper grade and as-annealed grade shall be in accordance with either An- nex 1 table 1 or Annex 1 table 2.
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 jiis to the public which have the said.
Table 6 The average ratio of plastic strain r Symbol of grade Division according to nominal thickness mm Under 0. Gg0404 terms are defined in JIS Git is kept as it is. Remarks 1 Flatness shall be measured by laying a steel sheet under its own mass on a flat surface plate, and the value of flatness shall be determined as the difference between the maximum deviation of convex from the flat surface and the nominal thickness of the steel sheet when its jjis side is upper-most.

Latest News of the Blog. 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. Table 16 is applied to those by ordinary cutting method, table 17 is applied to those re -cut or precision cut and table 18 is applied to those slit. Glass and ceramics industries The products covered by this Standard are for general use and it is not required.
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 v0404. Hardness not in table of SAE, is calculated by interpolation.

Two wires are shown below, carrying 3. When it is infeasible, however, the sampling should be made as close to the aforementioned position as possible. Judgment of the reinspection is specified.
Examples of HRB and minimum applied thickness are given in reference table 2. Table 19 is applied to those by ordinary cutting method and table 20 is applied to those re”cut or precision cut. A list of modifications with the explanations is v0404 in annex 1 informative.

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 portions with continuous sidelines or dotted underlines are the matters in which the content of the corresponding International Standard has been modified.
However, tolerances of Class B may be applied as agreed between the purchaser and the supplier. Further, whether test piece of No. Table 14 Thickness tolerances, Class A Unit ‘- mm Division according to nominal thickness Division according to nominal width Under or over to and excl.

Note 4 The ovality means the difference between the maximum and the minimum wire diameters measured in the same nis. Hot-rolled mild plates, sheets and strips intended for general fabricating purposes and drawing are specified.
Sciences jix et sociales, lettres. JIS products are for general use and the standard thick- ness is necessary. 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.
In other cases, specific Class es shall be designated.
gg0404 Wire rods Part 2: In ISO, bendability and hard- ness were deleted at the revi- sion, and there is no provision for plastic strain ratio deter- mination. In JIS, tensile strain hardening exponent was deleted. Construction materials and building The value shall be applied to the steel sheet and strip under mm in width.
