Relevance

modern industry conditions impose products and metal constructions special requirements. It is necessary to resist the action of aggressive fluids, gases, high temperatures, high mechanical loads. Martensitic-ferritic steel 12H13, temperature-resistant and heat-resistant corrosion-resistant. It contains 12−14% chromium, 0.12% carbon, doped silicon, manganese, nickel. Used for the production of increased ductility of parts that can withstand t ° 450−500 ° C, shock, vibration and contact with a slightly aggressive environment at normal temperature. Substitute — Steel 20X13.

Technological properties

forging temperature starts 1230 ° C, the end section 850. Rolled up to 100 mm is cooled in air, section 101−350 mm — in the pits. Mark 12H13 prone to temper brittleness Weldability limited. Used welding: RDS, DT submerged, Ards, CCC. Pre-heating and final heat treatment are applied depending on the welding process and the appointment structure. Machinability — Kv TV. cpl = 0.8 Kv and b. CT = 0.5 in the quenched and tempered condition with HB 235 and Rm = 730 MPa.
