Steel 1065 vs 1095
Steel · grade comparison
Steel 1065 and 1095 are both steel grades, both high carbon steel. Both yield at about 380 MPa — strength does not separate them. 1095 runs hotter in service (400°C vs 350°C continuous). On the shop floor, 1065 welds better (25 vs 15 out of 100) and 1095 forms better (fair vs poor).

1065 vs 1095: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all steel grades in the FabDigit library; each bar is drawn as a share of that.
- The better value (by the usual engineering direction) is in bold. Rows with no direction — density, thermal conductivity — have no bold.
- Values are typical room-temperature figures for the condition named on each card.
- Confirm against the certified mill or resin datasheet before design release.

1065 vs 1095 — frequently asked
What is the difference between 1065 and 1095?
Steel 1065 and 1095 are both steel grades, both high carbon steel. Both yield at about 380 MPa — strength does not separate them. 1095 runs hotter in service (400°C vs 350°C continuous).
Which is cheaper, 1065 or 1095?
Both sit in the same relative cost tier ($$, standard); the part price will be decided by machining time, tolerance and quantity rather than by the material.
Which welds better, 1065 or 1095?
1065. Its weldability rates poor (25/100) against poor (15/100) for 1095.
