JIS G3141 PDF

When a material grade is specified as cold rolled steel, it means it has been subjected to a manipulative process of cold rolling in which a metal bar is passed through high tension rollers below the re-crystallization temperature of the steel. The roller does not only decrease the thickness of the sheets but also refines the grain structure and hardens the steels. Also, after the cold rolling process there are some additive processes like rewinding, annealing, and then skin passing to make a complete SPCC material with bright finish. However the width of SPCC material ranges to mm.

When a material grade is specified as cold rolled steel, it means it has been subjected to a manipulative process of cold rolling in which a metal bar is passed through high tension rollers below the re-crystallization temperature of the steel. The roller does not only decrease the thickness of the sheets but also refines the grain structure and hardens the steels. Also, after the cold rolling process there are some additive processes like rewinding, annealing, and then skin passing to make a complete SPCC material with bright finish.

However the width of SPCC material ranges to mm. Maximum percentage of Manganese Mn is 0. Maximum percentage of Phosphorous P is 0. Maximum percentage of Sulphur S is 0. Remaining is iron Fe percentage and with few negligible impurities.

The elongation property of SPCC steel varies with the ranges of thickness. The minimum percentage ranges for elongation is from 27 to 31 percent starting from 0. The weld ability of these materials is conformed. These are also used in different applications of Construction. SPCC cold rolled steels coils are also consumed in galvanized products, for example GI coils, and color plates etc.

These are also extensively used in making of electrical appliances, containers. Pipes and drum manufacturing is also one of the common application of SPCC materials. Moreover the iron armature used in tube lights chalk is also manufactured through SPCC steel.

Other common applications of SPCC materials are: fan blades, frying pans,wall mount kits, metal stamping kit,and ceiling mount kit etc. The supplier address is Room , No. Limited bearing contact number Supplier Daewon Steel Co. The supplier address is , Jungwang-dong, Siheung-si Gyeonggi-do Korea. Commercial Quality Mild Steel Grades Relationship Matrix The figure 1 illustrated below in the article shows that how different mild steel grades are linked together with different processes, material grades are represented in blue boxes where as industrial processes are presented in green boxes.

The figure is explained by a supporting article below. Once the billets for commercial quality hot rolled SPHC steel is prepared with the due chemical composition in the melt shop, then it is rolled to form hot rolled slabs, the slabs are further re-rolled above the re-crystallization temperature to form hot rolled coils with material grade of SPHC steels. Learn about SPHC steels. SPHC steels served as a raw material for many material grades as illustrated in the figure.

Depends on the reduction percentage the material is hardened. Hardness is less than or equal to 55 HRB. This annealed material is not a finished cold roll steel and thus it is skin-passed with one and half percent reduction to give SPCC-SB steels. Similar with case of SPCC-SD steels, the only difference is that the work rolls are shot blasted to give a dull finish to steel. The change is about 0. Bagikan ini:.
