Steel 1095 vs A229

Steel · grade comparison

Steel 1095 and A229 are both steel grades. A229 is the stronger of the two: yield strength 1,320 MPa (191 ksi) against 380 MPa (55.1 ksi) for 1095, about 3.5 times as much; tensile strength follows at 1,550 MPa (225 ksi) vs 655 MPa (95 ksi). In exchange, 1095 is the more ductile: elongation 13% versus 7% for A229, and A229 is harder (430 HB vs 192 HB). 1095 runs hotter in service (400°C vs 150°C continuous). On the shop floor, 1095 machines more easily (fair vs poor) and A229 sits in a lower cost tier (budget, $) than 1095 (standard, $$).

1095Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.

A229Choose it when strength drives the design, or when cost is the deciding factor.
