Steel Heat Treatment
I need parts solution treated and aged, or quenched and tempered, to an aerospace specification. Who is accredited for my material?
What it is
Solution treating, aging, annealing, normalizing, quenching and tempering in air, controlled atmosphere or salt. The route for aluminum and most steels, where reactive and refractory metals instead require vacuum.

Bodycote Reported
Steel alloys named; all industrially significant heat treatments are offered for ferrous metals, including carburising and ferritic nitrocarburising. CAVEAT: Bodycote operates 245 plants in 21 countries and WHICH plant holds WHICH approval is not established from these sources. A NADCAP thermal processing approval belongs to a furnace at a named site, not to the corporate brand. Confirm the plant before qualifying to it.

ELLWOOD National Forge Verified
Vertical heat treatment on site, which is what long gun tubes require to avoid distortion.

McInnes Rolled Rings ReportedAS9100
In-house annealing, normalising, quenching and tempering. Ring properties are set by the post-roll thermal cycle, so keeping it in house removes a transfer and a second approval.
