stainless steels containing nickel remain ductile at extremely low temperatures but can operate at high temperatures. Nickel-containing SS plumbing pipe have excellent formability and weldability. The nonmagnetic material is also different from conventional steels and non-nickel stainless steels. Because of their versatility, they can be used in a wide range of applications, including those for the chemical industry, healthcare, and domestic use. The nickel content in stainless steel water pipe is so crucial that it accounts for 75% of the total production. There are two types best known for their nickel content: Type 304, which has 8%, and Type 316, which has 11%.
Steel crystal structure changes from a martensitic to an austenitic (face-centered cubic crystal structure) structure when nickel is added. The ambient temperature ferritic steel has a cubic body and crystal structure. These unique properties are imparted by an adequate amount of nickel - typically 8-10%.
