Stainless Steel 1.4807 vs 1.4849
Stainless Steel · grade comparison
Stainless Steel 1.4807 and 1.4849 are both stainless steel grades. Both yield at about 240 MPa — strength does not separate them. 1.4849 is the more ductile: elongation 10% versus 9% for 1.4807. On the shop floor, 1.4849 welds better (good vs fair).
1.4849Choose it when the part is bent, formed or impact-loaded, or when it will be welded.
1.4807 vs 1.4849: 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.

1.4807 vs 1.4849 — frequently asked
What is the difference between 1.4807 and 1.4849?
Stainless Steel 1.4807 and 1.4849 are both stainless steel grades. Both yield at about 240 MPa — strength does not separate them. 1.4849 is the more ductile: elongation 10% versus 9% for 1.4807.
Which is cheaper, 1.4807 or 1.4849?
Both sit in the same relative cost tier ($$$$, high); the part price will be decided by machining time, tolerance and quantity rather than by the material.
Which welds better, 1.4807 or 1.4849?
1.4849. Its weldability rates good (55/100) against fair (40/100) for 1.4807.
