Relevance

The conditions of modern industry impose special requirements on products and metal structures. It is necessary to resist the action of aggressive solutions, gases, high temperatures, significant mechanical loads. Martensitic-ferritic steel 12Х13 is heat-resistant and heat-resistant to corrosion. It contains 12-14% of chrome, 0.12% of carbon, alloyed with silicon, manganese and nickel. It is used for production of highly ductile parts that can bear 450-500°С temperature, impact loads, vibration and contact with slightly aggressive media at normal temperature. Substitute - steel 20X13.

Technological properties

Forging temperature: start 1230 °C, end 850 °C. The rolled section up to 100 mm is cooled in the air, 101-350 mm - in the pits. Grade 12X13 is prone to temper embrittlement Weldability is limited. The following welding methods are used: РДС, АДС under flux, АДС, КТС. Preheating and final heat treatment are used depending on the method of welding and the purpose of construction. Machinability by cutting - Kv tv. spl = 0.8 and Kv b.st. = 0.5 in hardened and tempered condition at HB 235 and σv = 730 MPa.

Note. To increase the corrosion resistance it is recommended to heat treat the parts as follows: hardening at 950-1000°C in oil or in the air; tempering at 650-700°C or polishing.
