[QUOTE="ntsqd, post: 1947715, member: 93138"] Nitriding is probably worth looking at. The racing engine shop that I worked for did a process known as "Cool Case" hardening to the crankshaft journals. Hardening won't have any effect on throat erosion, but I can see other benefits. Don't know enough about 416SS, it may not be possible to use this process on it. There are more than a couple stainless alloys that can't be hardened. There is a whole family of carbon steels out there known as "HSLA's" (High Strength Low Alloy). Many of these were developed specifically to deal with abrasion. that there could be one that deals well with abrasion at high temperature would not come as a shock. Alloying a "stainless steel" to have these properties may have already been going on. The amateur metallurgist in me wonders how close this new alloy is to Carpenter 625 or any of the other "Super" SS alloys. [/QUOTE]
