Stainless Steel 1.4876-ANN vs 1.4876-AW

Stainless Steel · 1.4876 temper comparison

1.4876-ANN and 1.4876-AW are two conditions of the same stainless steel grade, 1.4876: ANN (annealed) versus AW (as-welded deposit). The chemistry is identical, so every difference below comes from the condition. 1.4876-AW is the stronger of the two: yield strength 300 MPa (43.5 ksi) against 250 MPa (36.3 ksi) for 1.4876-ANN, about 20% more. In exchange, 1.4876-ANN is the more ductile: elongation 43% versus 35% for 1.4876-AW, and 1.4876-AW is harder (165 HB vs 140 HB).
