Stainless Steel 1.4005 vs 410

Stainless Steel · grade comparison

Stainless Steel 1.4005 and 410 are both stainless steel grades. 1.4005 is the stronger of the two: tensile strength 550 MPa (79.8 ksi) against 517 MPa (75 ksi) for 410, about 6% more. 1.4005 is harder — 175 HB against 155 HB for 410 — which matters for wear surfaces and threads. 1.4005 is stiffer (215 GPa vs 200 GPa) and 1.4005 conducts heat better (30 W/m·K vs 24.9 W/m·K). On the shop floor, 1.4005 machines more easily (excellent vs good), 410 welds better (fair vs poor), and 410 forms better (good vs poor).

1.4005Choose it when strength drives the design, or when surface hardness matters.

410Choose it when it will be welded.
