Ống thép không gỉ không hàn ASTM A312 TP304 is an austenitic alloy grade designed with a superior composition of nickel and chromium. The ASTM A312 TP304 alloy has excellent resistance against corrosive and oxidative media across stress-induced environments. The versatile grade of alloys has outstanding mechanical properties. They have a minimum tensile strength of 75ksi with a minimum yield strength of 30Ksi. The ASTM A312 Grade TP304 Seamless Pipe can be processed via the hot or cold rolling process. These pipes can be availed in thickness between 0.8mm up to 12mm and can be availed in different sizes and dimensions to meet project requirements.
The components in this grade are produced in seamless, welded, and ERW configurations. Each of these modules has its own set of features allowing them to be used in different applications. The ASME SA 312 TP 304 Seamless Pipe is produced via an extrusion process wherein hot steel billets are passed through the metal. Ống thép không gỉ không hàn ASTM A312 TP304 allows the material the capability to work in high temperatures and pressures. More over these pipes are slightly expensive as compared to welded pipes.

Xử lý nhiệt
Stainless steel pipes made of austenitic stainless steel ASTM A312 TP304 or TP304L shall be solution annealed. ASTM A312 TP304 Stainless steel seamless pipe During annealing, the pipes shall be heated to the temperature no less than 1900°F [1040°C] and soak at the temperature for a period long enough so that all chromium carbides are dissolved. Since the chromium carbide dissolves slowly, the highest practical temperature consistent with limited grain growth should be selected. This temperature is in the vicinity of 1095° [2000°F]. Complete dissolution of chromium carbides reduces precipitation of intergranular carbides hence improves the resistance to intergranular corrosion. Subsequent cooling (quenching) from the annealing temperature must be fast, thus ensuring that dissolved carbides remain in solution.
