... attacked the Inconel 601, forming various sulfides and chlorides. Recommendations included on-site testing, and installation of test coupons of various alloys before fabricating another kiln. The suggested alloys were RA85H, 800HT, HR-120, Haynes 556, and HR-160. Sulfurization Inconel 601 UNS...

... at high strain rates, such as in the accident rollover, the fracture mode might be one of brittle (cleavage) fracture. However, if failure was caused by slow application of loads, such as those of normal vehicle use, the failure mode might be more ductile in nature. Impact test coupons were used to obtain...

... another type 309 stainless steel preheater/exchanger. In order to evaluate more resistant alloys for this application, corrosion coupons of various alloys were assembled into a test rack and placed in the gas stream ahead of the new type 309 exchanger. The corrosion information obtained from the test rack...
