Stainless Steel 430FSe-CD vs 430FSe-HR
Stainless Steel · 430FSe temper comparison
430FSe-CD and 430FSe-HR are two conditions of the same stainless steel grade, 430FSe: CD (cold drawn) versus HR (hot rolled). The chemistry is identical, so every difference below comes from the condition. 430FSe-CD is the stronger of the two: yield strength 550 MPa (79.8 ksi) against 345 MPa (50 ksi) for 430FSe-HR, about 59% more; tensile strength follows at 655 MPa (95 ksi) vs 550 MPa (79.8 ksi). In exchange, 430FSe-HR is the more ductile: elongation 22% versus 15% for 430FSe-CD, and 430FSe-CD is harder (215 HB vs 185 HB).
430FSe-CDChoose it when strength drives the design.
430FSe-HRChoose it when the part is bent, formed or impact-loaded.
430FSe-CD vs 430FSe-HR: 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.

430FSe-CD vs 430FSe-HR — frequently asked
Is 430FSe-CD stronger than 430FSe-HR?
Yes. 430FSe-CD has a typical yield strength of 550 MPa (79.8 ksi) against 345 MPa (50 ksi) for 430FSe-HR — about 59% more. Tensile strength is 655 MPa (95 ksi) vs 550 MPa (79.8 ksi).
Which condition does FabDigit quote by default, CD or HR?
A is the default 430FSe condition in the FabDigit quote flow (neither CD nor HR). The other condition is available on request or by drawing note — specify it in the material field or the part notes and the quote is priced for it.
Which is easier to machine, 430FSe-CD or 430FSe-HR?
430FSe-CD. Its machinability rates very good (70/100) against good (64/100) for 430FSe-HR.
