Stainless Steel SUS436L Annealed vs SUS436L-AW
Stainless Steel · SUS436L temper comparison
SUS436L Annealed and SUS436L-AW are two conditions of the same stainless steel grade, SUS436L: Annealed versus AW (as-welded deposit). The chemistry is identical, so every difference below comes from the condition. Both yield at about 300 MPa — the mechanical properties are the same, and the difference is in how the stock is processed and what it is certified to (Annealed versus as-welded deposit). SUS436L Annealed is the more ductile: elongation 30% versus 20% for SUS436L-AW, and SUS436L-AW is harder (165 HB vs 155 HB).

SUS436L Annealed vs SUS436L-AW: 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.

SUS436L Annealed vs SUS436L-AW — frequently asked
What is the difference between SUS436L Annealed and SUS436L-AW?
SUS436L Annealed and SUS436L-AW are two conditions of the same stainless steel grade, SUS436L: Annealed versus AW (as-welded deposit). The chemistry is identical, so every difference below comes from the condition. Both yield at about 300 MPa — the mechanical properties are the same, and the difference is in how the stock is processed and what it is certified to (Annealed versus as-welded deposit).
Which condition does FabDigit quote by default, Annealed or AW?
Annealed is the default SUS436L condition in the FabDigit quote flow. 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.
When should I choose SUS436L Annealed over SUS436L-AW?
Pick SUS436L Annealed when the part is bent, formed or impact-loaded.
