Stainless Steel 1.4416-AC vs 1.4416-AW

Stainless Steel · 1.4416 temper comparison

1.4416-AC and 1.4416-AW are two conditions of the same stainless steel grade, 1.4416: AC (spheroidize annealed) versus AW (as-welded deposit). The chemistry is identical, so every difference below comes from the condition. Both yield at about 290 MPa — the mechanical properties are the same, and the difference is in how the stock is processed and what it is certified to (spheroidize annealed versus as-welded deposit). 1.4416-AW is the more ductile: elongation 28% versus 20% for 1.4416-AC, and 1.4416-AC is harder (190 HB vs 180 HB). On the shop floor, 1.4416-AW welds better (65 vs 55 out of 100).

1.4416-AC vs 1.4416-AW — frequently asked

What is the difference between 1.4416-AC and 1.4416-AW?

1.4416-AC and 1.4416-AW are two conditions of the same stainless steel grade, 1.4416: AC (spheroidize annealed) versus AW (as-welded deposit). The chemistry is identical, so every difference below comes from the condition. Both yield at about 290 MPa — the mechanical properties are the same, and the difference is in how the stock is processed and what it is certified to (spheroidize annealed versus as-welded deposit).

Which condition does FabDigit quote by default, AC or AW?

SA is the default 1.4416 condition in the FabDigit quote flow (neither AC nor AW). The other condition is available on request or by drawing note — specify it in the material field or the part notes and the quote is priced for it.

Which welds better, 1.4416-AC or 1.4416-AW?

1.4416-AW. Its weldability rates good (65/100) against good (55/100) for 1.4416-AC.
