Spring Bar Steel, Hot Rolled (56Si7)

The advantage of our hot rolled spring steel is that there are high thicknesses possible. As the tensile strength of the bars is 900-1100 N/mm² it may be necessary to do a heat treatment after fabrication of your parts an before using them.

The bars can be cut in length according to your wishes.

Information	the capacity to spring derives from the elastic formability the required properties are reached through higher ratios of carbon and other alloying additions as silicon, manganese, chrome, molybdenum and vanadium as well as through heat treatment
Heat Treatment	appropriate to be tempered in oil
