Hello All:
ASTM A291 dictates the minimum tempering temperatures that shall be followed.
My questions
1. What is the reason for dictating the minimum tempering temperature ?
2. Can you go any lower on the tempering temperatures (when hardness is not achieved) and what are the risks in doing...
Hello Everyone,
I am working on a flue gas system, the gas stream contains 0.068% - SO2; 40.962% - H2O;7.29 % - O2; 4.47% - CO2 i calculated the dew point temperature using two different equations and came up with 160.30 deg C and 162.90 deg C. My question is if i want to operate below the dew...
I need some technical help; I have a situation where I need to take decision on a casting with graphite flotation. So I would like to know if you have some information (an equation or something) to correlate mechanical properties and graphite flotation (from micro-structure), so that I can...
Hi Everyone,
I am looking for brazing vendors to braze Tungsten Carbide. I need vendors who can handle huge parts example something in the dimensions of 2 meters X 2 meters X 1.5 meters. If anyone has such information on the vendors who had such huge brazing furnaces please provide me the...
I am looking for material selection for flue gas cold stack for petroleum coke calcining plant. We use Mg(OH)2 slurry to reduce sulfur. The process conditions are as follows:
H2SO4 emissions 20 ppmvd upto 30 ppmvd.
O2 - 11.92%
chlorides - 350-500ppm coming from HCl from flue gas
- Flue gas...
