YUHONG GROUP we are one of the leading manufacturer for heat exchanger tube in China.With more than 35 years' development ,we have a great many clients all around the world exporting 85 countries .YUHONG products also won the great praise among the clients .
Specification ASTM A268 covers a number of grades of nominal-wall-thickness, stainless steel tubing for general corrosion-resisting and high-temperature service. Most of these grades are commonly known as the “straight-chromium” types and are characterized by being ferromagnetic. Two of these grades, TP410 and UNS S 41500 (Table 1), are amenable to hardening by heat treatment, and the high-chromium, ferritic alloys are sensitive to notch-brittleness on slow cooling to ordinary temperatures. These features should be recognized in the use of these material.The grades contain TP410, TP405, TP420, TP430, TP430Ti, TP403, TP409, TP444, TP439 and TP446.
The tubes shall be made by the seamless or welded process with no filler metal added, tubes shall be reheated to a temperature of 1200.F [650.C] or higher and cooled to meet the requirements of this specification, All tubes shall be free of excessive mill scale, suitable for inspection. A slight amount of oxidation will not be considered as scale.
TP410 contains the minimum amount of chromium to impart stainless steel properties. tp resists oxidation and scaling up to 1200 degF. Hardness is one of tp10’s best features; It resists abrasion and wear better than most 300 series stainless steel.
To produce SA 268 tp410 round tubing, there seem to be three different manufacturing processes: seamless, welded, and ERW.
The raw metal is initially cast to produce a more usable beginning shape in both manufacturing processes. The heated metal billet is then stretched into a seamless tube, or the ends of a flat metal strip are pressed together and then combined by a weld.
Extrusion is a method of producing steel where a workpiece, often a circular chuck, is pushed to pass through a die with a decreasing cross-sectional surface, changing the shape of the work to the resulting cross-section.
