Alloyed structural steel 25CrMo4
High-strength alloy structural steel, grade 25CrMo4, refers to chromium-molybdenum alloys.
Made from unalloyed steels, by hardening, for further hardening and tempering, as well as induction hardening. Conforms to European standard EN10083.
Material supplied as:
– Hot formed semi-finished products.
– Prutkov.
– Bars.
– Hot-rolled sheets and strips.
– Forgings.
Special Properties
European steel grade EN10083 stands out for its convincing strength, sufficiently high yield strength and significant impact strength. It completely retains its mechanical properties at an operating temperature of 450-500 degrees.
The material has limited weldability. Manual arc welding or automatic submerged arc welding can be used.
Applications
Structural materials represented by steel grades 25CrMo4 are used in production of billets, fasteners, flanges, disks and rotors of steam turbines, parts of various machines.
