PRODUCT DETAILS
Product introduction
Product Description
The astm a335 P91 pipe is a seamless Pipe meant for high temperature applications. These pipes are made from ferritic Alloy-Steel.
Chemically the a335 P91 welded pipe contains elements like Molybdenum (Mo) and Chromium added to the alloy. When Molybdenum
and chromium are added to the alloy, there is an increase in the tensile strength of the sa335 grade P91 pipe. The tensile strength of
the a335 grade P91 pipe is 415 Mpa, while its yield strength is 205 Mpa. The elongation percentage of the pipe ranges between 20% to 30%.
Alloy Steel P91 Seamless Pipes is often referred to as excellent steel due to its increased resistance to chloride corrosion making it a very
suitable material for use in salt water environments.
