Why do stainless steel prices change so often?
Short answer
Stainless steel and nickel alloy prices track their alloy content. Mills add alloy surcharges based on recent nickel, molybdenum, chromium and iron prices, so a move in nickel shows up within weeks in SS 316L and much more in high-nickel alloys such as 625. Quote validity, timing and lower-nickel alternatives help manage the risk.
Key takeaways
In brief
- Alloy content drives price: A tonne of SS 316L contains about 100–140 kg of nickel and 20–30 kg of molybdenum.
- Managing risk: Request quote validity periods, consider lower-nickel alternatives such as duplex 2205 where technically suitable, and order early for long-lead nickel alloys.

Which grades move most with nickel
| Grade | Approx. nickel content | Price sensitivity |
|---|---|---|
| Duplex 2205 | ≈ 5% | Low |
| SS 304L | ≈ 8–10% | Moderate |
| SS 316L | ≈ 10–14% + Mo | Moderate to high |
| SS 904L | ≈ 23–28% + Mo, Cu | High |
| Alloy 625 | ≥ 58% | Very high |
Comparing quotes fairly
When comparing offers, check whether the price is fixed or subject to surcharge at delivery, which month's surcharge applies, and how long the quote is valid. Two quotes for the same SS 316L pipe can differ by the surcharge month alone. See what drives metal prices.

Frequently asked questions
What is an alloy surcharge?
A price adjustment that mills add to a base price to reflect recent raw-material costs, mainly nickel, molybdenum and chromium for stainless steels.
Is duplex cheaper than SS 316L?
Per kilogram it is often similar or slightly higher, but its low nickel makes it less sensitive to nickel price swings, and its higher strength can reduce weight.
How long are your quotations valid?
Validity depends on the grade and market conditions and is stated on each quotation. High-nickel alloys usually carry shorter validity.
