The N80 oil and gas API casing pipe contains N80-1 and N80-Q types. These two materials are consistent in the chemical composition and mechanical properties, and are just different in the heat treatment. This type of product is commonly used in the oil drilling process.

As its mechanical properties are higher than J55 and K55 types, it can be applied to some slightly more complicated formations. With deeper downhole depth than J55 and K55 types, it can be used for the exploitation of middle-level oil and gas. Due to the high performance of N80 material, this API casing pipe is extensively used in natural gas and coal bed methane extraction, as well as geothermal wells.
