A286 (ASTM A638) nicyuma cya austenitike cyimvura ikomera igumya guhindagurika no gukomera kwubushyuhe bwa kirogenike, bitandukanye nicyuma cya ferritic cyangwa martensitike kiba cyoroshye. Kumasoko ya kirogenike, ibikoresho mubisanzwe nibisubizo bivurwa kandi imyaka igakomera kugirango imvura igwe neza. Coefficient $ \ alpha $ igomba kubarwa mugushushanya inteko, kuko isoko izagabanuka kurenza amazu yicyuma cya karubone gikikije ubushyuhe bwa azote. Modulus $ E $ nayo yiyongera gato uko ubushyuhe bugabanuka, biganisha ku gipimo cyo hejuru cyimpeshyi muri serivisi.
