Steel A285 vs P195TR2

Steel · grade comparison

Steel A285 and P195TR2 are both steel grades. A285 is the stronger of the two: yield strength 250 MPa (36.3 ksi) against 235 MPa (34.1 ksi) for P195TR2, about 6% more; tensile strength follows at 450 MPa (65.3 ksi) vs 370 MPa (53.7 ksi). A285 is harder — 130 HB against 115 HB for P195TR2 — which matters for wear surfaces and threads. A285 runs hotter in service (425°C vs 300°C continuous). On the shop floor, A285 machines more easily (68 vs 55 out of 100) and P195TR2 sits in a lower cost tier (budget, $) than A285 (standard, $$).

A285Choose it when strength drives the design, or when surface hardness matters.

P195TR2Choose it when cost is the deciding factor.
