ASTM A268 TP430 1.4016 Seamless Tube With Good Corrosion Resistance
ASTM A268 is a Standard specification for Seamless and Welded Ferritic and Martensitic Stainless Steel Tubing for General Service, the grades contain TP410, TP405, TP420, TP430, TP430Ti, TP403, TP409, TP444, TP439 and TP446.
This specification 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 S41500, 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 materials.
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.
430 Stainless Steel is a low-carbon plain chromium ferritic stainless steel. The steel has good corrosion resistance in mildly corrosive environments and good resistance to oxidation at elevated temperature. In the annealed condition the steel is ductile, does not harden excessively during cold work and can be formed using a large variety of roll forming or mild stretch-bending operations, as well as the more common drawing and bending processes.
