Tus naj npawb thiab kev sawv cev ntawm 304 stainless hlau yeeb nkab
① Siv cov cim tshuaj lom neeg thoob ntiaj teb thiab cov cim hauv tebchaws los sawv cev cov tshuaj lom neeg, thiab cov ntawv Arabic los sawv cev cov ntsiab lus: xws li: Tuam Tshoj, Russia 12CrNi3A
②Siv tus lej tas los sawv cev rau steel series lossis cov lej; xws li: Tebchaws Meskas, Nyiv, 300 series, 400 series, 200 series;
③ Tus lej xov tooj yog tsim los ntawm cov ntawv Latin thiab cov kab ke, uas tsuas yog qhia lub hom phiaj.
Tuam Tshoj' txoj cai lej
①Siv cov cim cim ②Lub hom phiaj, Suav pinyin, qhib-hearth steel: P, boiling steel: F, tua steel: B, Class A steel: A, T8: tshwj xeeb 8, GCr15: pob ◆ alloy steel, caij nplooj ntoos hlav steel, xws li: 20CrMnTi 60SiMn, (siv ob peb kaum txhiab los qhia cov ntsiab lus ntawm C) ◆ Stainless hlau, hlau alloy hlau (siv ob peb txhiab los qhia cov ntsiab lus C), xws li: 1Cr18Ni9 ib txhiab (xws li 0.1% C), stainless C ≤ 0.08% xws li 0Cr18Ni9, Ultra-low carbon C≤0.03% xws li 0Cr17Ni13Mo
International stainless hlau marking method
Lub koom haum American Hlau thiab Hlau siv peb tus lej los qhia ntau qib txheej txheem ntawm forgeable stainless hlau. Ntawm lawv: ①Austenitic stainless hlau yog qhia los ntawm 200 thiab 300 series tooj, ②Ferritic thiab martensitic stainless hlau yog qhia los ntawm 400 series tooj. Piv txwv li, qee cov austenitic stainless hlau feem ntau yog cim nrog 201, 304, 316 thiab 310, ③ ferritic stainless hlau yog cim nrog 430 thiab 446, thiab martensitic stainless hlau yog cim nrog 410, 420 thiab 440C. Duplex (austenite-ferrite), ④Stainless hlau, nag lossis daus hardening stainless hlau thiab siab alloys nrog hlau ntsiab lus tsawg tshaj li 50% feem ntau yog muaj npe los ntawm patent npe lossis cov cim lag luam.
