Uses
Low-alloy engineering steel with enhanced hardenability and strength from alloying elements. Chromium (≈0.975%) improves hardenability, wear and corrosion resistance. Molybdenum (≈0.575%) raises high-temperature strength and prevents temper embrittlement. Vanadium (≈0.3%) refines grain and strengthens the tempered structure. 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).
