Stainless Steel 410 vs 410Cb
Stainless Steel · grade comparison
Stainless Steel 410 and 410Cb are both stainless steel grades. 410 is the stronger of the two: yield strength 310 MPa (45 ksi) against 290 MPa (42.1 ksi) for 410Cb, about 7% more; tensile strength follows at 517 MPa (75 ksi) vs 490 MPa (71.1 ksi). 410Cb is harder — 170 HB against 155 HB for 410 — which matters for wear surfaces and threads. On the shop floor, 410Cb welds better (good vs fair).
410Choose it when strength drives the design.
410CbChoose it when surface hardness matters, or when it will be welded.
410 vs 410Cb: 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.

410 vs 410Cb — frequently asked
Is 410 stronger than 410Cb?
Yes. 410 has a typical yield strength of 310 MPa (45 ksi) against 290 MPa (42.1 ksi) for 410Cb — about 7% more. Tensile strength is 517 MPa (75 ksi) vs 490 MPa (71.1 ksi).
Which is cheaper, 410 or 410Cb?
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, 410 or 410Cb?
410. Its machinability rates good (55/100) against fair (50/100) for 410Cb; for welding the order is 410Cb first (good, 60/100) then 410 (fair, 45/100).
