ASTM A213 T22, izwi kandi nka ASME SA213 T22, ni umuyoboro w'icyuma udakora neza ufite chromium ya 1.90–2.60% na molybdenum ya 0.87–1.13% nk'ibintu by'ingenzi bivangavanze, bikunze gukoreshwa mu byuma bishyushya, ibishyushya cyane, n'ibihindura ubushyuhe mu bidukikije bifite ubushyuhe bwinshi kandi bifite umuvuduko mwinshi.
Icyitonderwa cya UNS ni K21590.
Botop Steelni umucuruzi w’imiyoboro y’ibyuma bya alloy w’umwuga kandi wizewe akaba n’umucuruzi w’ibicuruzwa mu Bushinwa, ushobora gutanga vuba imiyoboro y’ibyuma bya alloy nziza ku mishinga yawe.
Ibicuruzwa byose bishyigikira igenzura ry’umuntu wa gatatu, kandi dushobora no gutanga ibikoresho bihuye n’ibyo bikozwe mu cyuma nk’inkokora n’ibindi bikoresho by’imiyoboro.
imiyoboro y'icyuma ya T22 igomba gukorwa nainzira idahindagurikakandi igomba kuba irangiye ishyushye cyangwa ikonje, nk'uko byavuzwe.
Imiyoboro yose y'icyuma ya T22 igomba kongera gushyushywa kugira ngo ikoreshwe mu buryo bushyushye, ibyo bikaba bigomba gukorwa ukwabyo ndetse no mu buryo bwo gushyushya kugira ngo ikoreshwe mu buryo bushyushye.
Uburyo bwemewe bwo kuvura ubushyuhe ni ugukora inzoga yuzuye cyangwa isothermal, cyangwa gutunganya no gushyushya.

Byongeye kandi, imiterere ya ASTM A213 T22 ni imwe n'iya T2, T5, T5c,T11, T17, na T21.
Ingano z'imiyoboro ya ASTM A213 T22 n'ubugari bw'inkuta akenshi bishyirwaho uburebure bw'imbere buri hagati ya mm 3.2 na mm 127, naho ubugari bw'inkuta buri hagati ya mm 0.4 na mm 12.7.
Birumvikana ko niba umushinga wawe ukeneye izindi ngano, nabyo biremewe, igihe cyose ibindi bisabwa byose muri ASTM A213 byujuje.
Ibisabwa ku rugero rwa ASTM A213 byo kwihanganira ibintu ni bimwe kandi byashyizwe ku rutonde rwaImiyoboro y'icyuma ya T11 alloyUshobora gukanda kugira ngo urebe niba bikenewe.
Imiyoboro y'icyuma idafite umugozi ya ASTM A213 T22 ikoreshwa cyane mu mikorere y'ubushyuhe bwinshi n'umuvuduko mwinshi, cyane cyane mu nganda zikora amashanyarazi, peteroli, na peteroli na gaze.
Porogaramu zisanzwe zirimo:
Imiyoboro y'amazi yo gutekazikoreshwa mu byuma bishyushya cyane, ibishyushya, n'ibikoresha amashanyarazi mu nganda z'amashanyarazi.
Ibikoresho byo guhinduranya ubushyuhebikoreshwa mu bimera bya shimi na peteroli.
Imiyoboro y'ifuruzikoreshwa mu bikoresho byo mu itanura rishyushye cyane.
Imiyoboro y'umwukazikoreshwa mu gutwara umwuka ushyushye cyane mu nganda.
