Stainless Steel VG-10-ANN vs VG-10 SANMAI

Stainless Steel · VG-10 temper comparison

VG-10-ANN and VG-10 SANMAI are two conditions of the same stainless steel grade, VG-10: ANN (annealed) versus SANMAI (san-mai clad). The chemistry is identical, so every difference below comes from the condition. VG-10 SANMAI is the stronger of the two: yield strength 1,000 MPa (145 ksi) against 460 MPa (66.7 ksi) for VG-10-ANN, about 117% more; tensile strength follows at 1,400 MPa (203 ksi) vs 780 MPa (113 ksi). In exchange, VG-10-ANN is the more ductile: elongation 15% versus 6% for VG-10 SANMAI, and VG-10 SANMAI is harder (61 HRC vs 20 HRC). VG-10-ANN runs hotter in service (400°C vs 180°C continuous). On the shop floor, VG-10-ANN machines more easily (fair vs poor).

VG-10-ANN vs VG-10 SANMAI — frequently asked

Is VG-10 SANMAI stronger than VG-10-ANN?

Yes. VG-10 SANMAI has a typical yield strength of 1,000 MPa (145 ksi) against 460 MPa (66.7 ksi) for VG-10-ANN — about 117% more. Tensile strength is 1,400 MPa (203 ksi) vs 780 MPa (113 ksi).

Which condition does FabDigit quote by default, ANN or SANMAI?

HT60 is the default VG-10 condition in the FabDigit quote flow (neither ANN nor SANMAI). 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, VG-10-ANN or VG-10 SANMAI?

VG-10-ANN. Its machinability rates fair (35/100) against poor (20/100) for VG-10 SANMAI.
