Applications

高强度转子轴。,Forging

Available Forms

Low-alloy engineering steel with enhanced hardenability and strength from alloying elements. Chromium (≈1.15%) improves hardenability, wear and corrosion resistance. Molybdenum (≈0.225%) raises high-temperature strength and prevents temper embrittlement. Nickel (≈1.5%) 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.

Uses

Austenitize at 820–870 °C (oil or water quench depending on section) and temper at 400–650 °C to the required strength/toughness balance.

Heat Treatment

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).
