Dab tsi yog qhov tshwj xeeb ntawm A335 P5 yeeb nkab?
ASTM A335 P5 / ASME SA335 P5 yeeb nkab, chromium ntsiab lus yog 4. . Kuj hu ua P5 qib chromium-molybdenum alloy yeeb nkab, nws yog tsim seamlessly siv nyob rau hauv kub thiab corrosive ib puag ncig. Ua raws li tus qauv welded yeeb nkab hauv ASTM A691 5CR, nws yog ua los ntawm ASTM A387 qib 5 steel phaj.
A335 P5 yeeb nkab yog seamless alloy steel yeeb nkab rau kev siv kub, uas belongs rau American ASTM tus qauv.
A335 P5 yeeb nkab muaj cov yam ntxwv ntawm lub zog ruaj khov, siab oxidation tsis kam, kev ruaj ntseg zoo thiab kev ua haujlwm zoo. Nws yog tsuas yog siv los ua kom kub thiab kub siab boiler superheaters, reheaters, chav kav dej thiab lwm yam khoom.
Cov tshuaj muaj pes tsawg leeg ntawm A335 P5 kav dej muaj xws li carbon, silicon, manganese, phosphorus, sulfur, chromium, molybdenum thiab lwm yam khoom. Cov ntsiab lus carbon yog tswj hauv qab no 0.15%, thiab cov ntsiab lus chromium thiab molybdenum yog 4.0% ~ 6.0% thiab 0.45%~{ {10}}.65% feem. .
Cov txheej txheem tsim khoom ntawm A335 P5 cov kav dej suav nrog cov cua kub cua sov, cov khoom siv ntxhib, ua tiav dov, ntuj txias, sizing, tshuaj xyuas, warehouses thiab lwm cov kauj ruam. Cov cua kub cua sov yog tswj ntawm 1070 ~ 1180 degree, thiab kev tswj qhov kub ntawm qhov ntxhib dov thiab tiav dov yog feem 1000 ~ 1100 degree thiab 980 ~ 1050 degree.
