TISCO Hot Rolled Stainless Steel Coil 3MM - 14MM Thickness Professional

?

Description:

STAINLESS STEELS are iron-base alloys that contain a minimum of about 12% Cr,the amount needed to prevent the formation of rust in unpolluted atmospheres (hence the designation stainless). Few stainless steels contain more than 30% Cr or less than 50% iron.They achieve their stainless characteristics through the formation of an invisible and adherent chromium rich oxide film. This oxide forms and heals itself in the presence of oxygen. Other elements added to improve particular characteristics include nickel, manganese, molybdenum, copper, titanium, silicon, niobium, aluminum, sulfur, and selenium. Carbon is normally present in amounts ranging from less than 0.03% to over 1.0% in certain grades.

?

Different Finished Surface Characteristic:

No 1: Some of the thinner thicknesses within the plate range are Cold Rolled; but Sheet, Coil and Strip gauges are produced by Cold Rolling, ie rolled without and heating of the material. Cold Rolling hardens the material, and the thinner sizes may have to be subjected to an intermediate anneal and pickle, or bright annealed, during the reduction of thickness to final gauge The starting material for Cold Rolling always has a No. 1 finish. Cold Rolled material is supplied with the following standard mill finishes.

?

No 2A: A no. 1 Finish after being Cold Rolled, Annealed, Pickled and Passivated. This results in a uniform dull matt finish, superior to a No. 1 Finish. Suitable for industrial application, and eminently suitable for severe deep drawing as the dull surface, (which may be polished after fabrication) retains the lubricant during the drawing operation.

?

NO. 2B: The surface brightness and flatness of no2B is better than no2D. Then through a special surface treatment to improve its mechanical properties, No2B could nearly satisfy comprehensive uses.
