Stainless Steel 1.4607 vs 430

Stainless Steel · grade comparison

Stainless Steel 1.4607 and 430 are both stainless steel grades. Both yield at about 310 MPa — strength does not separate them. 1.4607 is harder — 165 HB against 155 HB for 430 — which matters for wear surfaces and threads. 1.4607 is stiffer (220 GPa vs 200 GPa) and 1.4607 runs hotter in service (950°C vs 815°C continuous). On the shop floor, 1.4607 welds better (excellent vs good).

1.4607 vs 430 — frequently asked

What is the difference between 1.4607 and 430?

Stainless Steel 1.4607 and 430 are both stainless steel grades. Both yield at about 310 MPa — strength does not separate them. 1.4607 is harder — 165 HB against 155 HB for 430 — which matters for wear surfaces and threads.

Which is cheaper, 1.4607 or 430?

Both sit in the same relative cost tier ($$, standard); the part price will be decided by machining time, tolerance and quantity rather than by the material.

Which is easier to machine, 1.4607 or 430?

430, by a small margin. Both rate fair for machinability — 50/100 against 45/100 for 1.4607; for welding the order is 1.4607 first (excellent, 85/100) then 430 (good, 60/100).
