Steel 1095 vs A228
Steel · grade comparison
Steel 1095 and A228 are both steel grades. A228 is the stronger of the two: yield strength 1,950 MPa (283 ksi) against 380 MPa (55.1 ksi) for 1095, about 5.1 times as much; tensile strength follows at 2,300 MPa (334 ksi) vs 655 MPa (95 ksi). In exchange, 1095 is the more ductile: elongation 13% versus 3% for A228, and A228 is harder (530 HB vs 192 HB). 1095 runs hotter in service (400°C vs 120°C continuous) and 1095 conducts electricity better (9.6 % IACS vs 8.6 % IACS). On the shop floor, 1095 machines more easily (fair vs poor).
1095Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
A228Choose it when strength drives the design.
1095 vs A228: 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.

1095 vs A228 — frequently asked
Is A228 stronger than 1095?
Yes. A228 has a typical yield strength of 1,950 MPa (283 ksi) against 380 MPa (55.1 ksi) for 1095 — about 5.1 times as much. Tensile strength is 2,300 MPa (334 ksi) vs 655 MPa (95 ksi).
Which is cheaper, 1095 or A228?
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 is easier to machine, 1095 or A228?
1095. Its machinability rates fair (45/100) against poor (16/100) for A228; for welding the order is 1095 first (poor, 15/100) then A228 (not recommended, 10/100).
