- Q: I have down hole application containing sour gas and high chloride levels. The temperature the bolts are exposed to is around 150F and I’m having trouble with cracking. I tried Super Duplex 2507 but am still having issues. Any ideas?
- Q: I need high yield strength material what is the difference between MP35N and A286? Which is more economic?
- Q: I need a material that will be suitable for oil and gas use. Submersion in hydrogen sulfide, carbon dioxide, hydrocarbons, salt water at temperatures up to 325F. Crevice corrosion has been a factor. Also need 170ksi min tensile strength. Plus we’d like to torque a 3/8-24 fastener to 50 ft lbs.
- Q: I needed a lightweight fastener and tried aluminum but it can’t come close to sustaining the weight of my application. Can you suggest anything compatibly light weight that is stronger?
- Q: I need to attach an LNG cryogenic pump and need to make sure I use a material that can withstand temperatures of –120 °F as well as don’t embrittle when fluctuating back to room temperature. Any suggestions?

A: Though ceramics are excellent insulators, they are usually only used for high temperature applications, where polymers are not compatible. For example Alumina ceramic has a usable limit of 1650°C. Since this is a relatively low temperature, your best bet is a … Continue reading
A: Of course it depends on the concentrations and temperatures you are operating at but generally speaking a very chemically resistant and strong polymer to consider would be PVDF or Kynar fasteners. PVDF fasteners offers an ultimate tensile strength of 5000-8000 psi … Continue reading
