Carbon-free maraging steels

Carbon-free maraging steels possess the high technological efficiency during the production of parts and strengthening within the ageing process.

VNS-25, VNS-49, VNS-59b=1000-1400 MPa) steels are applied for welded assemblies and parts, reliably operating at the cryogenic temperatures to -253°C. As compared to 12H18N10T austenitic steels, being used for the cryogenic engineering, these steels ensure significantly higher levels of strength, yield and toughness.

VNS-17b=1500 MPa) steel is used in the form of sheets, bars and hand forgings for fasteners, gears, including nitrified ones, rolled cowlings, vessels a.o. parts. The steel is applied for the production of upsetting fasteners, operating to 300°C (σb=1500 MPa) and to 500°C (σb=1300 MPa);

EP853 steel possesses the high hardness (HRC=54-56) at good ductility; it can be applied for flexible members and medical instruments;

VNS-36b=1450 MPa) steel is recommended for large-size primary parts, including welded ones, operating to 250°C.
