Peb tau xa 321 stainless hlau ntawv 1 * 1220 * 2440 rau peb cov neeg siv khoom los ntawm UAE

Cov Khoom Hemical

321 stainless hlau yog titanium-stabilized austenitic stainless hlau (zoo ib yam li 304 tab sis ntxiv titanium los tiv thaiv chromium carbide precipitation). Nws muaj kev tiv taus kub siab zoo heev thiab kev tiv taus corrosion intergranular.

Cov Tshuaj Muaj pes tsawg leeg (%):

Khoom Kev sau ua ke

Chromium (Cr) 17.0 – 19.0

Nickel (Ni) 9.0 – 12.0

Cov pa roj carbon (C) ≤0.08

Manganese (Mn) ≤2.0

Silicon (Si) ≤1.0

Phosphorus (P) ≤0.045

Sulfur (S) ≤0.03

Titanium (Ti) ≥5×C (yam tsawg kawg nkaus 0.4%)

Hlau (Fe) Qhov Nyiaj Tshuav

Cov Nta Tseem Ceeb

✔Kev ruaj khov kub siab (txog li 800-900°C)

✔Tiv taus carbide precipitation (sensitization) thaum lub sijhawm vuam

✔Zoo oxidation & corrosion tsis kam (zoo dua 304 hauv qee qhov chaw ib puag ncig)

Cov ntawv thov

Vim nws qhov kub tsis kam thiab weldability, 321 stainless hlau yog dav siv rau hauv:

Cov Cheebtsam ntawm Lub Cav Aerospace & Jet (cov tshuab tso pa tawm, cov chav hlawv)

Cov Khoom Siv Tshuaj Lom Zem & Petrochemical (cov khoom sib pauv cua sov, cov hlab siab)

Cov Kav Dej Kub thiab Cov Boilers (kev ruaj khov thermal)

Cov Tshuab Pa Tawm Tsheb (manifolds, catalytic converters)

Cov Khoom Siv Ua Khoom Noj & Tshuaj (qhov twg xav tau kev vuam)

Kev Kho Mob Kub & Cov Khoom Siv Rau Qhov Cub (vim yog kev tiv taus oxidation)
