- High reliability based on stable quality
- Engineering steel contains either nickel, chromium, molybdenum or carbon, or combinations of them, providing high strength, toughness, fatigue strength and hardenability. The material is used to make critical parts of automobiles, construction machinery and industrial machinery.
- Sanyo Special Steel responds to increasing needs by incorporating high-cleanliness steel production technology to manufacture high-quality engineering steel with less non-metallic inclusions.
|Carbon steel||Carbon steel is most extensively used as engineering steel, and its hardness can be controlled by adjusting the carbon content and performing thermal treatment.|
Alloy elements are added to enhance strength, toughness, fatigue strength and hardenability to manufacture alloy steel.
|Free cutting steel||Machinability is improved by adding elements such as sulfur or lead to manufacture free cutting steel.|
