Stainless Steel 1.4849 vs HF

Stainless Steel · grade comparison

Stainless Steel 1.4849 and HF are both stainless steel grades. HF is the stronger of the two: yield strength 310 MPa (45 ksi) against 250 MPa (36.3 ksi) for 1.4849, about 24% more; tensile strength follows at 620 MPa (89.9 ksi) vs 490 MPa (71.1 ksi). HF is the more ductile: elongation 38% versus 10% for 1.4849, and 1.4849 is harder (180 HB vs 165 HB). HF is stiffer (193 GPa vs 170 GPa) and 1.4849 runs hotter in service (1,050°C vs 870°C continuous). On the shop floor, HF machines more easily (30 vs 20 out of 100) and HF sits in a lower cost tier (premium, $$$) than 1.4849 (high, $$$$).

1.4849 vs HF — frequently asked

Is HF stronger than 1.4849?

Yes. HF has a typical yield strength of 310 MPa (45 ksi) against 250 MPa (36.3 ksi) for 1.4849 — about 24% more. Tensile strength is 620 MPa (89.9 ksi) vs 490 MPa (71.1 ksi).

Which is cheaper, 1.4849 or HF?

HF is the lower-cost material: it sits in the premium tier ($$$) while 1.4849 is high ($$$$). Part price depends far more on geometry, tolerance and quantity than on raw stock — upload a CAD file for a live quote.

Which is easier to machine, 1.4849 or HF?

HF, by a small margin. Both rate poor for machinability — 30/100 against 20/100 for 1.4849; for welding the order is 1.4849 first (good, 55/100) then HF (fair, 50/100).
