Ibyuma bitagira umuyonga ni ibyuma-bivanze cyane bifite imbaraga zo kurwanya ruswa ugereranije nandi mashanyarazi bitewe na chromium nyinshi. Ukurikije imiterere yabyo, bagabanijwemo ubwoko butatu nka ferritic, austenitis, na martensitike. Irindi tsinda ryibyuma bitagira umwanda ni ibyuma bikomera. Nibihuza ibyuma bya martensitike na austenitis.
Icyiciro cya 440C ibyuma bitagira umuyonga nicyuma kinini cya karubone martensitike. Ifite imbaraga nyinshi, irwanya ruswa iringaniye, hamwe no gukomera no kwambara. Icyiciro cya 440C kirashobora kugera, nyuma yo kuvura ubushyuhe, imbaraga zisumba izindi, ubukana no kwambara birwanya amavuta yose adafite umwanda. Ibirimo byinshi bya karubone bifite inshingano zo kubiranga, bituma 440C ikwiranye cyane na porogaramu nko gufata imipira n'ibice bya valve.
