Boiler Vessel Alloy Steel Phaj
Siv rau kev tsim kev tsheb ciav hlau, kev loj choj, kev hla hiav txwv, thiab lwm yam. Nws yuav tsum muaj lub zog siab, toughness, thiab tiv taus cov load thiab cuam tshuam ntawm dov Tshuag, thiab kom muaj kev qaug zog zoo, qee qhov kub thiab txias toughness thiab atmospheric. corrosion kuj. Cov hlau rau khi-welding txuas hniav yuav tsum muaj kev vuam zoo thiab tsis tshua muaj siab rhiab heev.
Hlau phaj (s) rau txuas hniav
Cov pa roj carbon steel rau kev tsim kho choj suav nrog A3q rau riveting choj qauv thiab 16q rau vuam choj qauv; low-alloy steel rau choj qauv muaj xws li 12Mnq, 12MnVq, 15MnVNq, 16Mnq, thiab lwm yam. Lub thickness ntawm tus choj steel phaj yog 4.5-50 hli.
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.
