34CrMo4 is an alloy structural steel with high endurance and creep strength at high temperatures. The material’s properties make it ideal for manufacturing cylinders and high-load structural components such as automotive and engine transmission parts. Its full potential is through quenching and tempering, or through high/medium frequency surface quenching combined with low/medium temperature tempering treatments.
