• Tensile and bending tests
• Tolerances on shape
• Any requirement from clients

High carbon steel is an ideal material for custom flat springs, custom clips, and custom sheet metal stampings. High Carbon Steel Strips combines ease of fabrication with good strength and surface finish, is valued for its strength properties and operates at significantly higher levels than the mild steel grades. High carbon steel strip can be finished to meet the needs of a wide range of products. Where tensile strength and hardness are required, High Carbon steels are the material of choice. High Carbon Steel Strips Grades : C60, C65, C70, C75, C85, HC-14, En 42 J, C-98, C-100, C-124, HC21 etc. We offer spring steel strip in various shapes and sizes according to your final uses. These have excellent hardens property and high yield strength. Clients can avail these at competitive prices.

high carbon steel blue 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. blue 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.
 
Steel C125S, 1.1224 - implementation and specification
Non-alloy carbon spring steel is used for leaf springs and springs with small cross-sections. It is characterized by low hardenability and high carbon range in relation to C90S, C75S, C85S, and C67S steel. Designed for spring elements requiring high elasticity and hardness.It does not show corrosion resistance, and during heat treatment it is exposed to decarburization and oxidation, which means that the material should be protected against treatment using a protective atmosphere. Poorly carried out treatment is associated with reduced fatigue strength.Products made of C125S steel and its equivalents are produced in the form of flat semi-finished products - cold rolled strips, small-format thin sheets. Tempering of C125S steel is carried out in oil, and after tempering the product shows the structure of tempered martensite.Products made of C125S steel are characterized by high tensile strength and yield strength. Thermal improvement consists in austenitising the product at a temperature of 780 - 860 and tempering at a temperature of 350 - 500 ℃.
