SS 316 & 316L Temperature effect
SS 316 & 316L Temperature effect
(OP)
Hello,
I have an issue that needs to be resolved, you don’t need to go into much detail other than a quick brief on the effects on SS 316 at process temperatures between 350 and 560 Deg.C. opposed to 316L.
Details:
Product is a pigment (an abrasive powder of <1um particle size), contains 5-10% ordinary silica sand (tonne/tonne). The pigment is inert, but there will also be a small percentage of chlorine, oxygen, CO2 and nitrogen entrained in the pigment. The chlorine will every now and again be in the form of HCl when we have large process upsets.
Regards,
Hugo

RE: SS 316 & 316L Temperature effect
SA240-316L material is not suitable for use above 850 degrees F (450 degrees C).
SA240-316 material is suitable for Code use up to 1500 degrees F (820 degrees C). This sounds awfully high to me, so be sure to check out the current Code edition.
I have not attempted to address the environmental corrosion issues, just the strength issue per the ASME Code.
Hope this helps

Can you come back with a little more description of your equipment.
