Uses
Low-alloy engineering steel with enhanced hardenability and strength from alloying elements. Chromium (≈0.25%) improves hardenability, wear and corrosion resistance. Nickel (≈0.2%) 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 760–820 °C and quench (oil/water) then temper at 150–400 °C for high hardness; spheroidize anneal (680–720 °C) improves machinability of the as-rolled bar.
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).
