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
