304 316L 2205 S31803 Stainless hlau phaj
Khoom nthuav qhia:
Kev tiv thaiv corrosion ntawm stainless hlau feem ntau yog nyob ntawm nws cov alloy muaj pes tsawg leeg (Cr, Ni, Ti, Si, Al, Mn, thiab lwm yam) thiab nws cov txheej txheem sab hauv.
Raws li kev tsim cov txheej txheem kub dov thiab txias dov ob yam, raws li cov ntaub so ntswg cov yam ntxwv ntawm cov hlau hom yog muab faib ua 5 pawg: austenite hom, austenite-ferrite hom, ferrite hom, martensite hom, nag lossis daus hardening hom.
Stainless hlau phaj nto du, muaj siab plasticity, toughness thiab mechanical zog, tsis kam mus rau acid, alkaline roj, tov thiab lwm yam xov xwm corrosion.Nws yog cov hlau alloy uas tsis xeb yooj yim.

SA588 SA387 Alloy Steel Phaj
Khoom nthuav qhia:
Raws li cov ntsiab lus ntawm cov ntsiab lus alloy tau muab faib ua:
Cov hlau tsis tshua muaj hlau (tag nrho cov ntsiab lus ntawm cov hlau alloy tsawg dua 5%),
Medium alloy steel (5% -10% ntawm tag nrho cov ntsiab lus alloy)
High alloy steel (tag nrho cov ntsiab lus alloy siab tshaj 10%).
Raws li cov hlau alloy muaj pes tsawg leeg rau hauv:
Chromium hlau (Cr-Fe-C)
Chromium-nickel steel (Cr-Ni-Fe-C)
Manganese hlau (Mn-Fe-C)
Silicon-manganese hlau (Si-Mn-Fe-C)

Hnav-Resisting Plate, Weathering Resistant Plate
Khoom nthuav qhia:
Qhov hnav-tiv taus steel phaj yog tsim los ntawm ob qhov chaw: cov pa roj carbon tsawg thiab cov alloy hnav-resistant txheej.Lub alloy hnav-resistant txheej feem ntau yog 1 / 3 ~ 1 / 2 ntawm tag nrho cov tuab.Thaum ua hauj lwm, lub matrix muab cov kev ua tau zoo xws li lub zog, toughness thiab plasticity, thiab cov alloy hnav-resistant txheej muab cov hnav-tiv taus kom tau raws li qhov yuav tsum tau ua ntawm kev ua haujlwm.
Lub alloy hnav-tiv taus txheej yog feem ntau chromium alloy, thiab manganese, molybdenum, niobium, npib tsib xee thiab lwm yam hlau alloy kuj ntxiv.Cov carbide nyob rau hauv cov ntaub so ntswg metallographic yog faib nyob rau hauv fiber ntau, thiab cov kev taw qhia fiber ntau yog perpendicular rau saum npoo.Lub microhardness ntawm carbide tuaj yeem ncav cuag siab dua HV1700-2000, thiab qhov tawv tawv tuaj yeem ncav cuag HRC 58-62.Alloy carbide muaj qhov ruaj khov ntawm qhov kub thiab txias, tswj lub siab hardness, tab sis kuj muaj cov khoom zoo antioxidant, nyob rau hauv 500 ℃ tag nrho siv.

S235JR S275JR S355JR Carbon Steel Phaj
Khoom nthuav qhia:
Cov phaj hlau tau muab faib ua cov phaj kub thiab txias dov.
Raws li hom hlau, muaj cov hlau zoo tib yam, cov hlau zoo, cov hlau alloy, lub caij nplooj ntoos hlav steel, stainless hlau, cov cuab yeej hlau, cov hlau tsis muaj cua sov, cov kabmob steel, silicon steel thiab cov ntawv hlau ntshiab.
Cov pa roj carbon zoo zoo tuaj yeem muab faib ua peb pawg raws li cov ntsiab lus sib txawv: carbon steel (C 0.25%), nruab nrab carbon steel (C yog 0.25-0.6%) thiab siab carbon steel (C & gt; 0.6%).
High quality carbon structural steel yog muab faib ua manganese ib txwm (0.25% -0.8%) thiab siab dua manganese (0.70% -1.20%), tom kawg muaj cov khoom zoo thiab cov khoom ua haujlwm.
