High carbon and case hardening steels （高碳和表面硬化钢）.pdf

Flat Carbon Europe High carbon and case hardening steels Reliable hot rolled steels for high quality products For a number of years ArcelorMittal has been developing its range of high carbon steels for re-rolling and heat treatment applications. We are continuing to improve our flexibility and process to meet our customers’ most stringent demands. General properties High carbon steels are characterised by their hardness after heat treatment. They can offer high strength ratings, including fatigue resistance. Case hardening steels are characterised by their ability to form a harder skin after heat treatment. Main advantages High carbon steels are designed for the are particularly suitable for screws, fasteners, Low transverse coil profile production of parts for intensive use. firing pins, rifle bolts, engine camshafts etc. As these products are frequently re-rolled Case hardening steels are suitable for parts after slitting, ArcelorMittal can supply, subjected to high pressures and/or extreme ArcelorMittal product technical properties in certain dimensions, coils with an extra impacts. ArcelorMittal produces a high- Low thickness tolerance flat profile that can be 1/2 or even 1/3 quality hot rolled strip suitable for fulfilling the of the standard tolerance defined by EN highest requirements for your end product. In view of the tolerance values required 10051:2010; on ArcelorMittal products a for finished products made from re-rolled crown lower than 60 μm can currently be Applications
