We hold expertise in providing a qualitative range of Blue Tempered Steel Strips to our clients at affordable prices. Owing to features like high efficiency, optimum performance and durable finish standards they are highly demanded in the market. Our ranges of these are used in various industries like automobile, cable and electronic industries.

In annealed and lightly rolled materials, they exhibit a large degree of elongation, and can withstand complex processing. Springs are used in plenty of applications in the present-day world. Even so, only a few people have a nodding acquaintance with the brass tracks of spring manufacturing and the different qualities needed for various functions. While coiling steel into a spiral of desired length and diameter is the primary and center-most stage of spring fabrication, other treatments during and after the procedure determine the quality of the product that reaches the consumer.

high carbon steel Annealed tempered spring steel strip is harder, less bendable, and has a higher degree of spring back. Finished products made from this material have better edge retention, which correlates to the material's other properties. Annealed spring steel strip is used widely in the manufacture of springs, prominently in automotive and industrial suspension applications. It is a high carbon steel with a very high yield strength. This material allows objects made of spring steel to return to their original shape despite significant deflection or twisting.

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. Weldability: The quenched tempered spring steel strip should not be welded because of the heat input to the structure and work hardening which can have a huge affected. In addition, hardness cracks by welding were provokated, as with all high carbon steels.
