38ХМФЮА steel is used: for the manufacture of critical parts of equipment engineering, operating at temperatures up to +500 °C.
Structural steel high quality chrome-molybdenum-vanadium with aluminium martensitic class.
|Bars and shapes||В32||TU 14-1-1703-76|
|Weldability||Limited weldability of high-alloyed steel. Requires heat treatment before welding (on leave of absence at 650-710 °C with cooling in air or quenching in water 1050-1100 °C), preheating to 200-300 °C of the welded parts. After welding to relieve stresses and reduce the hardness of the parts of a welded joint subjected to vacation at 650-710 °C.|
