Umbhobho wentsimbi ongenamthungoI-ASTM A335 P5ngumbhobho onamandla aphezulu, obushushu obuphezulu obusetyenziswa kakhulu kwi-boilers ephezulu yoxinzelelo, i-ultra-high-pressure kunye neenkqubo zemibhobho kwi-petroleum, iikhemikhali, amandla ombane kunye namanye amashishini. Umbhobho wentsimbi uneempawu ezibalaseleyo zoomatshini kunye nokumelana nobushushu, unokusebenza ngokuzinzileyo phantsi kobushushu obuphezulu kunye noxinzelelo oluphezulu, kwaye yenye yezinto ezibalulekileyo eziyimfuneko kwintsimi yoshishino.

I-ASTM A335 P5umbhobho wentsimbi wamkela iteknoloji yemveliso engenamthungo ukuze kuqinisekiswe ukufana kunye nokuhambelana kombhobho, inokumelana ne-corrosion efanelekileyo kunye nokumelana ne-oxidation, kwaye inokusetyenziswa kwiindawo ezibuhlungu ixesha elide ngaphandle kokusilela. Izinto zayo eziphambili ze-alloying ziquka i-chromium, i-molybdenum kunye ne-tungsten, ebonelela ngokugqwesileyo kokumelana nobushushu kunye nokumelana ne-oxidation, okwenza ukuba isebenze kakuhle phantsi kweemeko eziphezulu zokushisa.

Iindawo ekufakwe kuzo izicelo zibandakanya ubushushu obuphezulu kunye noxinzelelo oluphezulu olufana nokutsalwa kwe-oyile, izixhobo zekhemikhali, izibiyeli zesikhululo sombane, kunye nemizi-mveliso yamandla enyukliya. Umbhobho wentsimbi ongenamthungoI-ASTM A335 P5ayisetyenziswa ngokubanzi kuphela kwiiprojekthi ezintsha, kodwa isetyenziswa rhoqo ekugcinweni nasekuhlaziyweni kwezibonelelo ezikhoyo, inika isiqinisekiso esithembekileyo sozinzo oluqhubekayo lwemveliso yoshishino.
