Applications
Russian state standard (GOST) steel grade.
Available Forms
Bar, plate, sheet, tube, forgings, strip, wire
Uses
Low-alloy engineering steel with enhanced hardenability and strength from alloying elements. Nickel (≈3%) increases toughness and impact strength at low temperature. Applied to gears, shafts, bolts, connecting rods, pressure parts and heavy forgings in automotive, energy and machinery sectors.
Heat Treatment
Austenitize at 820–870 °C (oil or water quench depending on section) and temper at 400–650 °C to the required strength/toughness balance.
Precautions
Preheat and control interpass temperature when welding; post-weld heat treatment or stress relief is recommended to avoid hard-zone cracking. Use low-hydrogen electrodes. Protect from decarburization during heating (controlled atmosphere or protective coating).
