spring bar steel (hot rolled)

The advantage of our hot rolled spring steel is that there are high thicknesses possible.


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


Material Code 56Si7 (previous: 55Si7)
Material Number 1.5026
Quality according to DIN EN 10089
Tolerances according to DIN EN 10058 (cut edge) bzw. DIN 4620 (round edge)
Dimensions see spreadsheet below
Product flat bars with a length of approx. 5-6 m
Edges cut or round
Tensile strength (Rm): 900 to 1100 N/mm2 (without heat treatment)
Surface hot rolled, untreated
Information
  • appropriate to be tempered in oil
  • 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
