X14CrMoS17, 1.4104, X6CrMoS17, 1.4105 - specifications and applications
Stainless steels 1.4104 and 1.4105 are automatic stainless grades for the production of screws, nuts, parts and components with smaller cross-sections for turning machines. Classified as martensitic steels by the EN standard, they can be used in both tempered and annealed condition with similar properties to ferritic steel X6Cr17 / 1.4016, which applies mainly to material 1.4105 / X6CrMoS17. By analyzing the chemical composition of 1.4104 grade, increased carbon content can be observed, which enables thermal improvement and improvement of strength parameters, increased Sulphur content improving the machinability of the grade, and at the same time reduction of corrosion resistance. Grade 1.4105 is an equivalent of 1.4016 / X6Cr17 steel with increased Sulphur content. The grades are widely used in the petrochemical, automotive, food, garden and machinery industries for nitric acid plants, toolholders, fasteners, ball valves, basic fittings, furniture parts, vehicles, simple appliances and decorative elements. The grades are not suitable for welding. 1.4105 is not resistant to intergranular corrosion.
