ASTM A335 P5 yog ib qho kub-dov qis-alloy steel nrog chromium thiab molybdenum ua cov ntsiab lus tseem ceeb ntawm cov alloying, feem ntau muaj 9 feem pua chromium thiab 1 feem pua molybdenum. Chromium txhim kho cov khoom tiv thaiv oxidation thiab corrosion, thaum molybdenum boosts nws lub zog thiab toughness ntawm kub kub. Tsis tas li ntawd, cov hlau tsis tshua muaj carbon cov ntsiab lus pab tiv thaiv kev loj hlob ntawm cov nplej thiab kev khaws cia ntawm nws lub zog. Tsab ntawv "P" sawv cev rau "Pib", uas qhia tias cov hlau alloy feem ntau yog siv hauv cov kav dej. ASTM A335 P5 alloy steel yog tsim nyog rau kev kub siab thiab siab-siab daim ntaub ntawv xws li fais fab nroj tsuag thiab roj refineries vim nws lub zog siab, kub-resistant, thiab zoo heev corrosion kuj. Nws kuj muaj zog weldability thiab formability, ua kom yooj yim rau txheej txheem thaum lub sij hawm tsim khoom.
Lub zog thermal conductivity ntawm ASTM A335 P5 alloy steel tso cai rau nws thauj cov cua sov kom zoo txawm tias qhov kub thiab txias. Qhov no ua rau nws yog ib qho khoom siv zoo heev rau cov khoom siv hluav taws xob thiab lwm yam kev siv hluav taws xob kub uas xav tau kev sib kis tau zoo. Lwm qhov txiaj ntsig yog nws lub zog tensile zoo, uas tiv thaiv kev deformation thiab tawg txawm tias nyob rau hauv qhov hnyav heev. Qhov no feature tshwj xeeb tshaj yog nyob rau hauv cov xwm txheej uas muaj kev kub siab los yog mechanical stress.
P5 alloy steel feem ntau ua ke nrog lwm cov ntaub ntawv, xws li carbon steel lossis stainless hlau, los tsim cov yeeb nkab sib xyaw uas muaj peev xwm tiv taus ntau yam kev ua haujlwm. P5 alloy steels, zoo li tag nrho cov hlau alloy, raug nqi ntau dua li cov pa roj carbon monoxide vim yog cov nqi ntxiv ntawm cov hlau alloying. Txawm li cas los xij, nws qhov kev ua tau zoo heev hauv kev siv kub thiab kub siab ua rau nws muaj txiaj ntsig zoo rau lub sijhawm ntev, kev siv nyiaj ntau dua.
ASTM A335 P5 alloy steel yeeb nkab los ntawm TS yog feem ntau muab nyob rau hauv daim ntawv ntawm seamless tubing thiab muaj nyob rau hauv ntau qhov ntau thiab tsawg thiab thicknesses rau ntau yam kev siv.
