Ole paipa uelo a335 P91 e iai elemene e pei ole Molybdenum (Mo) ma le Chromium fa'aopoopo i le fa'amea. I le taimi o le Molybdenum
ma faʻaopoopo le chromium i le uʻamea, o loʻo i ai le faʻaopoopoga o le malosi o le paipa sa335 grade P91. Le malosi tensile o
o le paipa a335 grade P91 e 415 Mpa, ae o lona malosi e maua mai ai e 205 Mpa. Ole pasene ole fa'aumi ole paipa ole va ole 20% ile 30%.
Alloy Steel P91 Seamless Pipes e masani ona taʻua o le sila sili ona lelei ona o le faʻateleina o le teteʻe atu i le chloride corrosion ma avea ai ma mea sili.
mea talafeagai mo le faʻaaogaina i siosiomaga vai masima.
