St70-2 yog ib tus qauv carbon txheej txheem hlau hauv German txheem2. Nws muaj lub zog siab thiab lub zog zoo, thiab yog siv dav hauv cov chaw tsim khoom lag luam engineering rau ntau yam engineering cov khoom siv thiab cov tshuab tshuab. Ntawm no yog cov lus qhia ntxaws ntxaws:

Naming Fircention2

Nyob rau hauv lub npe "St 70 - 2" sawv cev "sawv cev" hlau ", uas txhais tau tias cov hlau hlau. Tus lej "70" qhia tau tias cov ntsiab lus carbon nruab nrab hauv cov hlau yog 0.70%, thiab "2" sawv cev rau qib zoo raws qib 2.
