Specify Alloy 690 by grade and product form
Alloy 690 is a high-chromium nickel alloy evaluated for corrosion and elevated-temperature service. Engineering suitability depends on the actual environment, design and governing code.
Supply scope
Plate, sheet, strip, round bar and cut material are reviewed against dimensions, delivery condition, inspection and source availability.
Commercial confirmation
MOQ, available sizes, delivery date, inspection scope and certificate availability are confirmed in the quotation. This page does not claim fixed stock.
Match the specification to the supplied product
| Product | Common reference | State in the RFQ |
|---|---|---|
| Plate, sheet and strip | ASTM B168 / ASME SB-168 | Thickness, width, length, condition, flatness, surface and edges |
| Rod and bar | ASTM B166 / ASME SB-166 | Diameter, tolerance, length, condition, straightness and machining allowance |
Confirm the applicable edition, grade coverage and project requirements before order placement. A common specification reference alone does not demonstrate compliance with a particular design code.
Technical references: VDM Alloy 690 data sheet and Special Metals alloy bulletin index. The agreed purchase specification controls acceptance.
