Both 1070 and 1095 are excellent grades of steel. However both have similar chemical and mechanical properties and purchasers often don’t understand the small but significant differences of 1070 and 1095 steel. Below are chemical and mechanical property differences of 1070 and 1095 as well as common applications for both steel grades.
Chemical Properties
1070 and 1095 steel have different chemical properties, notably for their carbon and manganese composition. The chemical properties of 1070 and 1095 steel are the following.
| 1070 | 1095 | |
| Carbon, C | 0.65-0.75% | 0.90-1.03% |
| Manganese, Mn | 0.60-0.90% | 0.30-0.50% |
| Sulfur, S (Max) | 0.050% | 0.050% |
| Phosphorous, P (Max) | 0.040% | 0.040% |
Mechanical Properties
Below are the mechanical properties of hot rolled and SACDc 1070 and 1095 steel.
Hot Rolled
| 1070 | 1095 | |
| Tensile Strength | 110,000 psi | 120,000 psi |
| Yield Strength | 59,000 psi | 66,000 psi |
| Elongation (2″) | 10% | 10% |
| Reduction in Area | 30% | 25% |
| Brinell Hardness | 212 | 248 |
Spheroidized Cold Drawn (SACDc)
| 1070 | 1095 | |
| Tensile Strength | 92,800 psi | 99,000 psi |
| Yield Strength | 71,800 psi | 76,000 psi |
| Elongation (2″) | 10% | 10% |
| Reduction in Area | 45% | 40% |
| Brinell Hardness | 192 | 197 |
To understand the machinability of different grades of steel, we often use a relative machinability rating percentage based on SAE1212 as 100%. 1070 grade steel in the cold drawn state is 55% and 1095 grade steel also as cold drawn is 42%. You can learn more about the differences of 1070 and 1095 by contacting Capital Steel & Wire to find out which steel grade we provide that best suits your application.
