Stainless Steel 1.4435-ANN vs 1.4435-FH

Stainless Steel · 1.4435 temper comparison

1.4435-ANN and 1.4435-FH are two conditions of the same stainless steel grade, 1.4435: ANN (annealed) versus FH (full hard). The chemistry is identical, so every difference below comes from the condition. 1.4435-FH is the stronger of the two: yield strength 1,100 MPa (160 ksi) against 260 MPa (37.7 ksi) for 1.4435-ANN, about 4.2 times as much; tensile strength follows at 1,350 MPa (196 ksi) vs 560 MPa (81.2 ksi). In exchange, 1.4435-ANN is the more ductile: elongation 55% versus 6% for 1.4435-FH, and 1.4435-FH is harder (385 HB vs 150 HB). 1.4435-ANN is stiffer (200 GPa vs 190 GPa) and 1.4435-ANN runs hotter in service (550°C vs 300°C continuous). On the shop floor, 1.4435-ANN machines more easily (fair vs poor) and 1.4435-ANN welds better (excellent vs good).

1.4435-ANNChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.

1.4435-FHChoose it when strength drives the design.
