In the petroleum industry, it is very likely that the temperature range lies between 700°F to 720°F. Using grades like 304 or even grade 316 may not be feasible simply because they could experience failure. Pipes aside, in a piping system, the pressure applied by the flow of media can wear out ordinary alloys. But if the user were to use Stainless Steel 310 Pipe Fittings, he would be choosing an alternative that saves cost in the long run. Unlike grade 304, which is very economical, grade 310 costs higher. The increased cost of the alloy is because of the inclusion of higher chromium content along with the use of nickel in moderation in the ASTM A403 Uns S31000 Tee. In petroleum refineries, there are catalytic recovery systems, which make use of this alloy.
The temperature in these systems alone lies in the range of 650°F and extends to a temperature of 1000°F. The thermal energy that is given off during these reactions amounts to a high level of heat. The introduction of 310 Stainless Steel Pipe Fittings was solely for the purpose of functioning in mildly cyclic environments, where the temperatures could rise as high as 2000°F. Due to the inclusion of nickel in its chemistry, it becomes possible for the ASTM A403 Wp310 Elbow to withstand such levels of heat, without losing significant strength. The heat resistant behavior alone makes grade 310 Stainless Steel Fittings ideal to be used in ore extraction, furnace as well as the petroleum industry.
