Tshuaj lom neeg cov tshuaj & cov yam ntxwv lub cev

Kev siv tshuaj lom neeg (raug)

Carbon (c): Tsawg dua los yog sib npaug rau 0.02% (tiv thaiv intergranular corrosion)

Chromium (cr): {19.0-23.0% (zoo oxidation tsis kam)

Npib tsib caug (ni): {23.0-28.0% (txhim kho kev ntxhov siab corrosion tawg tsis kam)

Molybdenum (mo): {4.0-5.0% (Superior Pitting / Crevice Corrosion Kuj)

Tooj Liab (Cu): {1.0-2.0}% (ua kom pom kev zoo hauv kev txo cov kua qaub).

Cov Khoom Siv Lub Cev

Ntom ntom: {8.0-8.24 g /m³

Melting taw tes: 1300-1390 degree

Thermal conductivity: 15 w / (map k)

Tsis muaj hlau nplaum ntawm chav tsev kub .

Cov Khoom Siv Neeg Kho Tshuab

Lub zog tensile: Ntau dua los yog sib npaug rau 490 MPa
Paib lub zog: {215-220 mpa
Elongation: Ntau dua los yog sib npaug rau 35%
Kev nyuaj: HB 200-240

Qhov zoo tshaj plaws rau cov hlab siab siab thiab cov txheej txheem nyuaj vim kev kub siab heev .

Cov ntsiab lus tseem ceeb

Acid Refantance

Superior kev ua haujlwm nyob rau hauv dilute sulluric acid ({0}}%, tsawg dua los yog sib npaug nrog 40 degree)} {.

Chloride tsis kam

Kev tiv thaiv zoo heev rau pitting, crevice corrosion, thiab scc hauv dej hiav txwv / chloride daws .

Kev txwv

Avoid in strong nitric acid or hydrochloric acid (>2% concentration) .

Khoom Noj & Khoom Noj

Surile reactors, muaj siab huv cov kua dej ua kua .

Machining & Vuam

Vuam

Siv tig los yog smaw nrog ER385 / E385 muab tub lim, tom qab Weld pickling yuav tsum .

Ntaub

Nquag nquag ua haujlwm tawv; siv kev txiav qis thiab tshwj xeeb txias .
