EN_US-Engineering-Product-Hot-Rolled-Heat treatable steel-High carbon OverviewTSN
Tata Steel offers a choice of hot-rolled heat-treatable steel. Its chemical composition and the production processes we employ ensure robust, consistent products.
High carbon steel
High carbon steels are characterised by high levels of resistance, hardness and strength. This grade is designed for parts which require reliable form stability during intensive use.
Typical applications are saw blades, safety-shoe toe caps, (bicycle) chains, clips and buckles for seatbelts, clutches, automotive components, valves, washers and springs.
C67mod is based on an intermediate chemistry so it can be used to cover both the C67 and C75 chemistries according to EN 10132. Thereby the C67mod provides optimum flexibility for the users covering both defined grades.
