Stainless Steel 1.4513 vs 430
Stainless Steel · grade comparison
Stainless Steel 1.4513 and 430 are both stainless steel grades. Both yield at about 300 MPa — strength does not separate them. 1.4513 is harder — 170 HV against 160 HV for 430 — which matters for wear surfaces and threads. 1.4513 is stiffer (220 GPa vs 200 GPa) and 430 conducts heat better (26 W/m·K vs 23 W/m·K). On the shop floor, 1.4513 welds better (very good vs good) and 1.4513 forms better (very good vs good).
1.4513Choose it when surface hardness matters, or when it will be welded.
1.4513 vs 430: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all stainless steel grades in the FabDigit library; each bar is drawn as a share of that.
- The better value (by the usual engineering direction) is in bold. Rows with no direction — density, thermal conductivity — have no bold.
- Values are typical room-temperature figures for the condition named on each card.
- Confirm against the certified mill or resin datasheet before design release.

1.4513 vs 430 — frequently asked
What is the difference between 1.4513 and 430?
Stainless Steel 1.4513 and 430 are both stainless steel grades. Both yield at about 300 MPa — strength does not separate them. 1.4513 is harder — 170 HV against 160 HV for 430 — which matters for wear surfaces and threads.
Which is cheaper, 1.4513 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, 1.4513 or 430?
1.4513. Its machinability rates good (55/100) against fair (50/100) for 430; for welding the order is 1.4513 first (very good, 82/100) then 430 (good, 60/100).
