Steel 25Cr2Ni4WA vs H11

Steel · grade comparison

Steel 25Cr2Ni4WA and H11 are both steel grades. 25Cr2Ni4WA is the stronger of the two: yield strength 990 MPa (144 ksi) against 510 MPa (74 ksi) for H11, about 94% more; tensile strength follows at 1,130 MPa (164 ksi) vs 800 MPa (116 ksi). In exchange, H11 is the more ductile: elongation 20% versus 13% for 25Cr2Ni4WA, and 25Cr2Ni4WA is harder (330 HB vs 200 HB). H11 runs hotter in service (540°C vs 350°C continuous) and 25Cr2Ni4WA conducts heat better (31 W/m·K vs 25 W/m·K). On the shop floor, H11 machines more easily (good vs poor), H11 welds better (fair vs poor), and H11 sits in a lower cost tier (standard, $$) than 25Cr2Ni4WA (premium, $$$).

25Cr2Ni4WA vs H11 — frequently asked

Is 25Cr2Ni4WA stronger than H11?

Yes. 25Cr2Ni4WA has a typical yield strength of 990 MPa (144 ksi) against 510 MPa (74 ksi) for H11 — about 94% more. Tensile strength is 1,130 MPa (164 ksi) vs 800 MPa (116 ksi).

Which is cheaper, 25Cr2Ni4WA or H11?

H11 is the lower-cost material: it sits in the standard tier ($$) while 25Cr2Ni4WA is premium ($$$). 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, 25Cr2Ni4WA or H11?

H11. Its machinability rates good (55/100) against poor (32/100) for 25Cr2Ni4WA; for welding the order is H11 first (fair, 35/100) then 25Cr2Ni4WA (poor, 20/100).
