ASTM A269 TP304 Seamless Tubes is the ideal basket material for heat treatment applications because of its resistance to extreme temperatures and its ability to maintain sufficient strength at high temperatures. Compared to most stainless steel alloys, a basket made from this alloy won’t lose shape as easily when holding parts through a rigorous heat treat application. Jet engines are incredibly unique in that they must withstand extreme temperatures. ASME SA 269 TP304 Tubing is a material specially optimized for some of the toughest manufacturing environments. At the maximum cruising altitude of an airplane, the average air temperature is -69.3°F. However, the combustion process can exceed temperatures of 2120°F. Although cooling technologies are used, temperatures easily exceed the tolerances of many metals.
We as Siddhgiri Tubes is a recognized exporter of SA 269 Grade TP304 Tubes, which is a high temperature nickel-chromium-cobalt-molybdenum alloy that is resistant to corrosion and oxidation. It has excellent strength and toughness in the cryogenic temperature range up to 2000ºF. This is due to the mixed crystal effects of niobium and molybdenum. This type of ASTM A269 TP304 Polish Tubing is found in heat shields, furnace hardware, gas turbine engine ducts, combustion liners and spray bars, chemical plant hardware and specialty seawater applications. It’s more expensive than other metals, but it’s worth it. It has one of the highest tolerances for extreme heat and doesn’t lose as much tensile strength at 2000°F as most grades of steel.
