Kev sib xyaw thiab lub luag haujlwm ntawm Oxygen
C10200 txhais los ntawm ob tus lej ntau dua li ib qho: tooj liab ntawm 99.95% yam tsawg kawg nkaus thiab cov pa oxygen ntawm 0.0010% siab tshaj plaws, nrog rau tag nrho lwm cov impurities tuav ntawm lossis qis dua 0.05%. Qhov kev sib xyaw ua ke no yog dab tsi cais cov qib los ntawm cov tawv tawv tooj liab, uas txhob txwm khaws cia 0.02 - 0.05 % oxygen. Cov qib oxygen qis qis tiv thaiv qhov tsim ntawm cov hnab ris yog tias cov khoom siv cua sov hauv qhov chaw txo qis xws li hydrogen, uas yog hom tsis ua haujlwm hu ua hydrogen embrittlement. Cov khoom uas yog brazed, welded los yog ci ntsa iab annealed yog li khaws lawv txoj kev ncaj ncees es tsis txhob tsim cov kab nrib pleb.

| Ua haujlwm txias, siab (H08) | 340 - 380 | 310 - 345 | 4 - 12 | 80 - 90 |
Xaiv lub temper yog qhov sib npaug ntawm formability thiab lub zog. Annealed cov ntaub ntawv khoov, flanges, nyiaj muas thiab npib yam tsis muaj cracking thiab yog txoj cai xaiv qhov chaw yog tsim tom qab xa khoom. Cov khoom siv ua haujlwm txias hnyav yog lub zog ntau dua thiab muaj zog tab sis tsis tshua muaj elongation, yog li nws yog siv rau cov khoom uas ua tiav kom loj ua ntej xa khoom, xws li sawb conductors thiab machined Cheebtsam.
