Engineering High Tensile Steels
High tensile steels or Alloy Steels have alloying elements and heat treatment processes that improves strength and durability of the steel. We process high tensile steels for both engineering and fabrication.
Engineering grades we commonly machine include:
| 4140 |
|---|
| AKA – W-Nr 1.7225, AS 4140, BS EN19A, AISI 4140, 709M |
| Readily available Cr Mo steel for applications requiring high tensile strength and toughness. |
| Responds well to nitriding and heat treatment |
| Available in Round, Hex, Square and Flat |
| Finishes include black, peeled, ground and chrome |
| 4140 data sheet |
| 4340 |
|---|
| AKA – W-Nr 1.6565, AS 4340, BS ~EN24, AISI 4340 |
| Ni Cr Mo steel with high tensile strength and toughness |
| Responds well to heat treatment especially in large cross sections |
| 4340 data sheet |
| EN26 |
|---|
| AKA – W-Nr 1.6745, AS X9940, BS 970 826 M 40 |
| High tensile steel with higher carbon content |
| Supplied in the hardened and tempered condition |
| EN26 data sheet |
Fabrication High Tensile Steels
High strength steels used for fabrication generally have a relatively low carbon content. This is to retain good weldability. The strength of the steel is improved using special heat treatment processes. These materials are also used as wear plates and cutting edges on earthmoving equipment.
| Fabrication grades we commonly process include: |
|---|
| Bisalloy 80, 400,450 |
| Hardox |
| Durax 1045 |
| Reo bar |
