65Mn CK67 high carbon cold rolled spring steel strip Hardened and Tempered Steel Strip Hardened and Tempered is a thermal process that strengthens steel strips through a controlled heating and cooling process. The hardening process involves heating the steel strip to above the rapidly cooling. The steel strip in this condition is extremely brittle and requires further treatment in the tempering. Then strips are reheated to a lower temperature and holding it at the given temperature for a given period of time. This process is done in an inert atmosphere to avoid oxidation. This type of steel strip has big degree of toughness and has excellent spring properties Standard AISI, ASTM, BS, DIN, GB, JIS Place of Origin China Material Hot Rolled Surface Polished Application shutter door, plastic trowel, bricklayer trowel, putty knives, scraper, springs, metal part, shoe insole, shoe accessories, blade, band saw blade Brand Name HENSON Width 2.0mm-300.0mm Length Customize Tolerance +/-10% Hardness 40-55HRC Surface nature, blue, yellow, white, polish Edge Slit,Round,Square MOQ 1000KGS Tolerance thickness+/-0.01mm max,width +/-0.05mm max Type strip,coil,sheet Coil ID 300-500 mm Tensile Strength 540-1575N/mm2 Yield Strength 370-1475N/mm2

Mill scale, is formed on the outer surfaces of plates, sheets or profiles when they are being produced by rolling hot iron or steel billets in rolling or steel mills. It looks like a hard brittle sand and is mainly composed of iron oxides, mostly ferric, and is bluish black in color. Being produced during the reheating, conditioning and hot rolling operation for the production of steel articles, the mill scale initially adheres to the steel surface and protects it from atmospheric corrosion, provided no break occurs in this coating. From the chemical and physical analysis performed on the scrap, and according to the european environmental rules, the material has been classified as a special non dangerous waste, listed in green list In particular the mill scale can be classified as follows: Einecs (european commission no.): 266-007-8 Waste code: 10 02 10 Basel code: b 12 30 Hs code: 2619.00
