Steel A283 vs A992

Steel · grade comparison

Steel A283 and A992 are both steel grades, both structural steel. A992 is the stronger of the two: yield strength 380 MPa (55.1 ksi) against 230 MPa (33.4 ksi) for A283, about 65% more; tensile strength follows at 500 MPa (72.5 ksi) vs 420 MPa (60.9 ksi). A992 is harder — 150 HB against 120 HB for A283 — which matters for wear surfaces and threads. On the shop floor, A283 forms better (very good vs good) and A283 sits in a lower cost tier (budget, $) than A992 (standard, $$).

A283Choose it when cost is the deciding factor.

A992Choose it when strength drives the design, or when surface hardness matters.
