Also known as Alloy 660, A286 bolts are a cost-effective material for high temperature strength – see why in this snapshot newsletter.
What specifications can you offer?
A286 is available in ASTM and many AMS standards (often required for aerospace applications) including: ASTM A453, AMS 5525, AMS 5726, AMS 5732, AMS 5737, AMS 5804.
What is the maximum usable temperature of A286?
Are there better materials for high temperature strength?
A286 screws are a good cost effective solution for high temperature strength, however other high performance materials in this category may be a better fit. These include:
Can you provide NAS parts in A286?
Yes. A286 is available in many NAS aerospace parts typically in the strain-hardened condition at 160 min UTS.
Can A286 provide corrosion resistance?
In terms of corrosion, A286 bolts are best used to minimize high temperature oxidation from exhaust streams and engine manifolds.
While A286 screws are a stainless steel and will hold up well to atmospheric corrosion, it is typically not used for harsh conditions such as acids. Its chemical content of chromium, nickel, and molybdenum is similar to austenitic stainless steels, and therefore provides aqueous corrosion resistance comparable to these steels.
Is A286 usable at subzero temperatures?
Many high strength materials can become brittle at low temperatures, but A286 is not one. Since it remains ductile at cryogenic temperatures, it can be a good choice for non-magnetic strength down to around -320°F.
