Stainless Steel 1.4507-CD vs 1.4507 SA-PLT
Stainless Steel · 1.4507 temper comparison
1.4507-CD and 1.4507 SA-PLT are two conditions of the same stainless steel grade, 1.4507: CD (cold drawn) versus SA-PLT (hot rolled plate, solution annealed and pickled). The chemistry is identical, so every difference below comes from the condition. 1.4507-CD is the stronger of the two: yield strength 800 MPa (116 ksi) against 600 MPa (87 ksi) for 1.4507 SA-PLT, about 33% more; tensile strength follows at 950 MPa (138 ksi) vs 820 MPa (119 ksi). In exchange, 1.4507 SA-PLT is the more ductile: elongation 32% versus 18% for 1.4507-CD, and 1.4507-CD is harder (300 HB vs 255 HB).

1.4507-CD vs 1.4507 SA-PLT: 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.

1.4507-CD vs 1.4507 SA-PLT — frequently asked
Is 1.4507-CD stronger than 1.4507 SA-PLT?
Yes. 1.4507-CD has a typical yield strength of 800 MPa (116 ksi) against 600 MPa (87 ksi) for 1.4507 SA-PLT — about 33% more. Tensile strength is 950 MPa (138 ksi) vs 820 MPa (119 ksi).
Which condition does FabDigit quote by default, CD or SA-PLT?
SA is the default 1.4507 condition in the FabDigit quote flow (neither CD nor SA-PLT). 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 welds better, 1.4507-CD or 1.4507 SA-PLT?
1.4507 SA-PLT. Its weldability rates good (65/100) against good (60/100) for 1.4507-CD.
