C60S, 1.1211, CK67, 1.221, Spring Steel Strip

 

C60S 1.1211 belongs to the class of quenched tempered spring steel strip. Thanks to his patented homogeneous structure and his tight tolerances this steel is often used for instrument making. Other applications include various types of springs with high tensile strength as a function of the diameter. Corrosion resistance: A carbon steel has no natural resistance to corrosion in the usual sense. He must be protected as required with an appropriate procedure before general corrosion. Heat treatment: By +QT it receives its application for the typical microstructure.
