Zitsulo zachitsulo ndi zitsulo zomwe zimagwirizanitsa ndi zinthu zosiyanasiyana zokwanira pakati pa 1.0% ndi 50% ndi kulemera kwake kuti musinthe mphamvu zake. Zitsulo za alloy zimasweka m'magulu awiri: zitsulo zotsika komanso zitsulo zazitali. Kusiyana pakati pa awiriwo kumatsutsidwa. Smith ndi Ismahemu amatanthauzira kusiyana kwa 4.0%, pomwe degarmo, et al. Nthawi zambiri, mawu akuti "alloy chitsulo" amatanthauza zitsulo zotsika kwambiri.
ASTM A335 ndi lingaliro lamphamvu kwa chitoliro chaching'ono cha alrieric chitoliro cha kutentha kwambiri. Covers server levels: P1, P2, P5, P5b, P5c, P9, P11, P12, P15, P21, P22, P23, P91, P92, P122, of which P5, P9, P11, P22, P91, P92 are used in practice the most extensive. Izi zimatulutsa khoma locheperako komanso locheperako molybdenum (lomwe limadziwikanso kuti Cr-moly) mapaipi achitsulo opangira kutentha. Chipika cholamulidwa ndi izi zidzakhala zoyenera kugwada, mbanja ndi zopangidwa chimodzimodzi, komanso nsabwe zowala. ASTM A335 P11, P21, P91 ndi P91 ndi P91 imagwiritsidwa ntchito m'mafakitale a mphamvu ndi matebulo, pomwe P9 ndi P9 amagwiritsidwa ntchito makamaka pokonzanso mafuta.
