standard for surface roughness on hot rolled steel

Standard for surface roughness on hot rolled steelJun 19, 2019 · I have problems with our technology ( bussines unit-stamping), regarding standards for roughness on hot rolled steel. I already found 3 standards, but it seems that no one is OK for them. Material is S355MC and according to DIN EN 10149-2 (S355 MC fit in here) standard for roughnes should be EN 10163-1, 10163-2.

Tata Steel - Metallic coated steel - Tata Steel in Europe

Tata Steel offers a wide choice of metallic coated steel. Our product line comprises forming and structural grades and high-strength and advanced high-strength steels. Our steels deliver benefits including weight savings and improved component performance.Surface preparation - SteelConstruction.infoInitial surface condition. Structural steel elements in new structures are usually either hot rolled sections or fabricated plate girders. The initial steel surfaces normally comply with rust grades A or B according to BS EN ISO 8501-1. Material that is pitted, i.e. rust grades C or D, should be avoided if possible, since it is difficult to clean all the corrosion products from the pits during surface preparation.Surface finish of hot rolled steel platesSurface finish of hot rolled steel plates Steel plates must have a workmanlike finish and must be free from defects and imperfections which may impair their proper workability and use. This may, however, include some minor imperfections, e.g. pittings, rolled-scale, indentations, roll marks, scratches and grooves which cannot be avoided despite the proper manufacturing.

Surface Finish of Cold Finished Steel - Northlake Steel

Dec 07, 2016 · A hot rolled bar comes out of the mill (produced at temperatures of 1600° F to 2200° F) with a rough, abrasive, discolored, and dirty surface. At these high temperatures, an iron scale forms on the surface of the bars. Youll see in the areas where the scale flakes off, that there can also be pits and other marks in the bar.Surface Finish - U.S. Steel15 microinches maximum roughness.

Such common stainless steel grades as 201, 304, 304L and 316L come in a standard 2B finish. 2D This finish is also achieved by cold rolling, heat treating and pickling, but, unlike 2B, does not receive the light rolling. This achieves a standard for surface roughness on hot rolled steel

ISO - ISO 7788:1985 - Steel Surface finish of hot-rolled standard for surface roughness on hot rolled steel

Steel Surface finish of hot-rolled plates and wide flats Delivery requirements Buy this standard This standard was last reviewed and confirmed in 2011.Hot-rolled steel surface roughnessWhen the hot-rolled steel sheet in the 3.4 ~ 4.4m Ra or less roughness, coating corrosion resistance and cold-rolled steel corrosion coatings fairly; when hot-rolled steel sheet roughness Ra of 7.0 ~ 9.0m, the coating corrosion layer coating with the hot rolled steel sheet without shot blasting treatment considerably the corrosion resistance; when hot rolled steel sheet roughness Ra of 9.0 to when Hot Rolled Steel & Cold Rolled Steel - Difference & The rolls induce plastic deformation. Thus, the yield strength of cold rolled steel is higher than that of hot rolled steel. As an example, a hot rolled steel product may have a yield strength of 235 MPa. In comparison, a cold rolled steel product with the same chemical composition has a
