Overview
SS 1.4539 pipes, also known as UNS N08904, are made up of a high amount of chromium, nickel and iron, which offer superior corrosion resistance, strength and toughness. It has low carbon content, copper and molybdenum, contributing to its excellent resistance to pitting and crevice corrosion.It's also well-suited for use in environments that require resistance to elevated temperatures and high levels of corrosion.
Which industries used?
Chemical processing
Oil and gas
Pharmaceutical
Chemical composition
The high chromium content promotes and maintains a passive film which protects the material in many corrosive environments. 1.4539 has a greater resistance to precipitation of ferrite and sigma phases on cooling and welding than other stainless steels containing molybdenum such as 316L and 317L. There is no risk of intercrystalline corrosion on cooling or welding due to the low carbon content. Its maximum service temperature is at 450°C.
