Low Alloy Product Jis Scr430 Steel Key Material For The Automotive Industry - China

"When domestic automakers are still using 20CrMo, why do Toyota and Honda dare to use cheaper JIS SCr430 steel for their transmission gears? The key lies in the 'performance lever' hidden in the JIS standard!" Precisely matching material properties with the automotive industry

The "Balance" of JIS SCr430 steel composition design (Compared to ASTM A29 5130)

- Cr content of 0.9-1.2%: Improved hardenability (oil quenching critical diameter 30% larger than S45C)

- Low carbon design (C ≤ 0.33%): Better weldability than medium carbon steel (40% lower crack sensitivity) Three core automotive applications

1 - Transmission system

- Gears/drive shafts: JIS SCr430 steel carbonitrided (surface hardness HRC 58-62, core hardness maintained at HRC 28-32) 2 - Chassis components

- Control arms/steering knuckles: Induction hardening (hardened layer depth 1.5-3mm, 70% increase in bending strength).

3 - Fasteners

- Engine bolts: Tempered at 430°C ±10°C** for optimal strength-toughness combination (avoiding the risk of hydrogen embrittlement).
