What Are You Looking For?
Engineering steels cover a wide variety of steels that are generally heat treated to produce high strength levels of 750 MPa and above. Typical applications include automotive engine and transmission components, bearings, rails, machine tools and wire ropes. Although engineering steels include carbon-manganese compositions (with a high C content), most contain small to large additions of other alloy elements, such as Cr, Ni, V, Mo, W, etc.
