A335 refers to the American standard: SA-335/SA-335M seamless ferritic alloy steel nominal pipe for high temperature, AISI 335 P11 Seamless Carbon Steel Pipe is a low-alloy heat-resistant steel, higher than GR.P12 (corresponding to my country's 15CrMo) Chromium content is slightly higher. AISI 335 P11 Seamless Carbon Steel Pipe is American standard high temperature seamless ferritic Alloy Steel Pipe. Ferrite is an interstitial solid solution in which carbon is dissolved in α-Fe, and is often represented by the symbol F. It has a body-centered cubic lattice, and its carbon-dissolving ability is very low, only 0.0008% carbon can be dissolved at room temperature, and the maximum carbon-dissolving ability is 0.02% at 727 °C. The ferrite grain boundary is smooth, twin crystals or slip lines are rarely seen in the grain, the color is light green and bright, and it becomes dark after deep corrosion. Ferrite in steel exists in the form of flakes, lumps, needles and nets. AISI 335 P11 Seamless Carbon Steel Pipe is mainly used in high temperature working environment, high pressure, ultra-high pressure, subcritical power station boiler, superheater, header and main steam conduit, etc.
