Product Description
astm a335 P91 yeeb nkab yog seamless yeeb nkab txhais tau tias rau kev siv kub. Cov kav dej no yog tsim los ntawm ferritic Alloy-Steel.
Chemically lub a335 P91 welded yeeb nkab muaj cov khoom xws li Molybdenum (Mo) thiab Chromium ntxiv rau cov hlau. Thaum Molybdenum
thiab chromium ntxiv rau cov hlau, muaj qhov nce ntawm lub zog tensile ntawm sa335 qib P91 yeeb nkab. Lub zog tensile ntawm
A335 qib P91 yeeb nkab yog 415 Mpa, thaum nws lub zog tawm los yog 205 Mpa. Qhov feem pua elongation ntawm cov yeeb nkab yog li ntawm 20% mus rau 30%.
Alloy Steel P91 Seamless Pipes feem ntau hu ua cov hlau zoo heev vim nws muaj zog tiv thaiv chloride corrosion ua rau nws zoo heev.
cov khoom tsim nyog siv rau hauv cov dej ntsev ib puag ncig.
