Structural steels are steels that meet specific strength and formability grades. Formability is expressed as elongation after the break of tensile test. Structural steels are commonly used for purposes such as load bearing, where the strength of the steel is an important design criterion.
Alloyed structural steel
This kind of steel, with suitable hardenability, after appropriate metal heat treatment, the microstructure is homogeneous sorbite, bainite or very fine pearlite, thus has higher tensile strength and showed (around 0.85), high toughness and fatigue strength, and low ductile to brittle transition temperature, can be used in the manufacture of section size larger machine parts. |

| Forging |
Preheat the steel carefully, heat to 1150 oC – 1200 oC maximum, hold until temperature is uniform throughout the section.
Do not forge below 850 oC.Following forging operation the work piece should be cooled as slowly as possible. |
| Heat Treatment | Heat steels to 800 oC – 850 oC, hold until temperature is uniform throughout the section and cool in furnace. |
| Hardness | Anneal: ≤220HB Q+T: 12-22HRC |
| Application | ASTM alloy 4140 steel bar, flat or plate material can be used for as wide variety of applications where greater toughness and wear resistance is needed over lower carbon grades.
