Patterned Alloy Steel Phaj
Cov phaj checkered muaj ntau yam zoo xws li cov tsos zoo nkauj, tiv thaiv skid, ntxiv dag zog rau kev ua haujlwm, txuag hlau thiab lwm yam. Nws yog dav siv nyob rau hauv kev thauj mus los, kev tsim kho, kho kom zoo nkauj, pem teb ib puag ncig cov cuab yeej, machinery, shipbuilding thiab lwm yam teb. Feem ntau hais lus, tus neeg siv tsis muaj qhov xav tau siab ntawm cov khoom siv kho tshuab thiab cov khoom siv kho tshuab ntawm cov phaj checkered, yog li qhov zoo ntawm cov phaj checkered feem ntau tshwm sim hauv cov qauv tsim tus nqi, tus qauv qhov siab, thiab cov qauv qhov siab sib txawv. Cov tuab tuab ntawm kev ua lag luam ntau ntawm 2.0-8mm, thiab dav dav yog 1250 thiab 1500mm.
Classification los ntawm thickness
Nyias steel phaj <4 hli (thinnest 0.2 hli), tuab steel phaj 4-60 hli, ntxiv-thick steel phaj 60-115 hli. Qhov dav ntawm cov phaj nyias yog 500-1500 mm; qhov dav ntawm cov phaj tuab yog 600-3000 hli. Lub hom steel ntawm tuab steel phaj Nws yog ib qho yooj yim tib yam li nyias steel phaj. Nyob rau hauv cov nqe lus ntawm cov khoom, nyob rau hauv tas li ntawd mus rau lub choj steel daim hlau, boiler steel daim hlau, tsheb manufacturing steel daim hlau, siab hlab ntsha steel daim hlau thiab multi-layer high-pressure nkoj steel daim hlau, uas yog purely tuab daim hlau, ib co hom steel phaj xws li tsheb. beam steel daim hlau (thickness 2.5-10 mm), qauv Steel daim hlau (thickness 2.5-8 mm), stainless hlau daim hlau, tshav kub-resistant steel daim hlau, thiab lwm yam. daim hlau nyias. 2. Lub phaj steel muab faib ua kub-kuav los tiag thiab txias-dov raws li dov.
Classified los ntawm lub hom phiaj
(1) Choj steel phaj (2) Boiler steel phaj (3) Shipbuilding steel phaj (4) Armor steel phaj (5) Tsheb steel phaj (6) ru tsev steel phaj (7) steel phaj (8) hluav taws xob steel phaj (silicon) steel ntawv) (9) Caij nplooj ntoos hlav steel phaj (10) Lwm yam
Classified los ntawm cov qauv
1. Hlau phaj rau lub nkoj siab: Siv peev R los qhia qhov kawg ntawm qib. Qib tuaj yeem qhia tau los ntawm qhov taw tes tawm los lossis cov ntsiab lus carbon lossis cov ntsiab lus alloying. Xws li: Q345R, Q345 yog qhov taw qhia tawm. Lwm qhov piv txwv: 20R, 16MnR, 15MnVR, 15MnVNR, 8MnMoNbR, MnNiMoNbR, 15CrMoR, thiab lwm yam yog sawv cev los ntawm cov ntsiab lus carbon lossis alloying ntsiab lus.
2. Hlau phaj rau vuam lub tog raj kheej roj: Siv peev HP los qhia qhov kawg ntawm qib, thiab nws qib tuaj yeem qhia tau los ntawm qhov taw tes tawm, xws li: Q295HP, Q345HP; nws kuj tuaj yeem qhia nrog cov ntsiab lus alloying, xws li: 16MnREHP.
3. Hlau phaj rau boiler: Siv cov ntawv qis g los qhia qhov kawg ntawm lub npe hom. Nws qib tuaj yeem qhia tau los ntawm qhov taw qhia tawm, xws li: Q390g; Nws kuj tuaj yeem qhia tau los ntawm cov ntsiab lus carbon lossis alloying, xws li 20g, 22Mng, 15CrMog, 16Mng, 19Mng, 13MnNiCrMoNbg, 12Cr1MoVg, thiab lwm yam.
4. Hlau daim hlau rau txuas hniav: Siv cov ntawv me me los qhia qhov kawg ntawm qib, xws li Q420q, 16Mnq, 14MnNbq, thiab lwm yam.
5. Hlau phaj rau tsheb nqaj hlau: Siv peev L los qhia qhov kawg ntawm qib, xws li 09MnREL, 06TiL, 08TiL, 10TiL, 09SiVL, 16MnL, 16MnREL, thiab lwm yam.
