Stainless Steel 310Cb-CD vs 310Cb STAB

Stainless Steel · 310Cb temper comparison

310Cb-CD and 310Cb STAB are two conditions of the same stainless steel grade, 310Cb: CD (cold drawn) versus STAB (stabilize annealed). The chemistry is identical, so every difference below comes from the condition. 310Cb-CD is the stronger of the two: yield strength 550 MPa (79.8 ksi) against 305 MPa (44.2 ksi) for 310Cb STAB, about 80% more; tensile strength follows at 760 MPa (110 ksi) vs 610 MPa (88.5 ksi). In exchange, 310Cb STAB is the more ductile: elongation 42% versus 25% for 310Cb-CD, and 310Cb-CD is harder (225 HB vs 165 HB).

310Cb-CDChoose it when strength drives the design.

310Cb STABChoose it when the part is bent, formed or impact-loaded.

310Cb-CD vs 310Cb STAB — frequently asked

Is 310Cb-CD stronger than 310Cb STAB?

Yes. 310Cb-CD has a typical yield strength of 550 MPa (79.8 ksi) against 305 MPa (44.2 ksi) for 310Cb STAB — about 80% more. Tensile strength is 760 MPa (110 ksi) vs 610 MPa (88.5 ksi).

Which condition does FabDigit quote by default, CD or STAB?

Annealed is the default 310Cb condition in the FabDigit quote flow (neither CD nor STAB). 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, 310Cb-CD or 310Cb STAB?

310Cb-CD. Its machinability rates fair (35/100) against poor (28/100) for 310Cb STAB.
