Whakaahuatanga Hua
Ko te putorino astm a335 P91 he paipa tuitui mo nga tono pāmahana teitei. Ko enei paipa he mea hanga mai i te Ferritic Alloy-Steel.
He matū kei roto i te putorino paiherea a335 P91 nga huānga penei i te Molybdenum (Mo) me te Chromium kua taapiri atu ki te koranu. A, no te Molybdenum
ka taapirihia te chromium ki te koranu, ka piki ake te kaha o te putorino sa335 grade P91. Ko te kaha tensile o
Ko te paipa a335 grade P91 he 415 Mpa, ko tona kaha tuku he 205 Mpa. Ko te paheketanga elongation o te paipa kei waenga i te 20% ki te 30%.
Alloy Steel P91 Seamless Pipes e kiia ana he rino tino pai na te kaha ake o te aukati ki te waikura pūhaumāota, he tino pai.
