Stainless Steel 1.4411 vs CA28MWV
Stainless Steel · grade comparison
Stainless Steel 1.4411 and CA28MWV are both stainless steel grades. CA28MWV is the stronger of the two: yield strength 760 MPa (110 ksi) against 620 MPa (89.9 ksi) for 1.4411, about 23% more; tensile strength follows at 1,035 MPa (150 ksi) vs 850 MPa (123 ksi). In exchange, 1.4411 is the more ductile: elongation 18% versus 13% for CA28MWV, and CA28MWV is harder (302 HB vs 275 HB). CA28MWV runs hotter in service (593°C vs 350°C continuous) and CA28MWV conducts heat better (24 W/m·K vs 17 W/m·K). On the shop floor, 1.4411 welds better (very good vs poor).
1.4411Choose it when the part is bent, formed or impact-loaded, or when it will be welded.
CA28MWVChoose it when strength drives the design, or when the part sees heat.
1.4411 vs CA28MWV: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all stainless steel grades in the FabDigit library; each bar is drawn as a share of that.
- The better value (by the usual engineering direction) is in bold. Rows with no direction — density, thermal conductivity — have no bold.
- Values are typical room-temperature figures for the condition named on each card.
- Confirm against the certified mill or resin datasheet before design release.

1.4411 vs CA28MWV — frequently asked
Is CA28MWV stronger than 1.4411?
Yes. CA28MWV has a typical yield strength of 760 MPa (110 ksi) against 620 MPa (89.9 ksi) for 1.4411 — about 23% more. Tensile strength is 1,035 MPa (150 ksi) vs 850 MPa (123 ksi).
Which is cheaper, 1.4411 or CA28MWV?
Both sit in the same relative cost tier ($$$, premium); the part price will be decided by machining time, tolerance and quantity rather than by the material.
Which is easier to machine, 1.4411 or CA28MWV?
1.4411. Its machinability rates fair (35/100) against poor (30/100) for CA28MWV; for welding the order is 1.4411 first (very good, 70/100) then CA28MWV (poor, 30/100).
