Stainless Steel N-155 (Multimet)-AW vs N-155 (Multimet)-CD

Stainless Steel · N-155 (Multimet) temper comparison

N-155 (Multimet)-AW and N-155 (Multimet)-CD are two conditions of the same stainless steel grade, N-155 (Multimet): AW (as-welded deposit) versus CD (cold drawn). The chemistry is identical, so every difference below comes from the condition. N-155 (Multimet)-CD is the stronger of the two: yield strength 760 MPa (110 ksi) against 430 MPa (62.4 ksi) for N-155 (Multimet)-AW, about 77% more; tensile strength follows at 1,000 MPa (145 ksi) vs 760 MPa (110 ksi). In exchange, N-155 (Multimet)-AW is the more ductile: elongation 25% versus 20% for N-155 (Multimet)-CD, and N-155 (Multimet)-CD is harder (285 HB vs 210 HB). N-155 (Multimet)-AW runs hotter in service (815°C vs 650°C continuous).

N-155 (Multimet)-AWChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.

N-155 (Multimet)-CDChoose it when strength drives the design.

N-155 (Multimet)-AW vs N-155 (Multimet)-CD — frequently asked

Is N-155 (Multimet)-CD stronger than N-155 (Multimet)-AW?

Yes. N-155 (Multimet)-CD has a typical yield strength of 760 MPa (110 ksi) against 430 MPa (62.4 ksi) for N-155 (Multimet)-AW — about 77% more. Tensile strength is 1,000 MPa (145 ksi) vs 760 MPa (110 ksi).

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

SA is the default N-155 (Multimet) condition in the FabDigit quote flow (neither AW nor CD). 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, N-155 (Multimet)-AW or N-155 (Multimet)-CD?

N-155 (Multimet)-AW. Its weldability rates very good (70/100) against good (65/100) for N-155 (Multimet)-CD.
