Engineering Steel
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.
| Major Grades | |
|---|---|
| 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 steel | Alloy elements are added to enhance strength, toughness, fatigue strength and hardenability to manufacture alloy steel. Tough and hard steel featuring extremely high viscosity is manufactured by applying quenching and tempering processes. Case hardening steel featuring high wear resistance and shock resistance is manufactured by carburization. H-type steel guarantees the hardenability of the steel materials mentioned above. |
| Free cutting steel | Machinability is improved by adding elements such as sulfur or lead to manufacture free cutting steel. |
