630 Stainless Hlau VS 316 Hlau

• SUS630 Khoom Taw Qhia:

SUS630 martensitic nag lossis daus hardening stainless hlau. Cov ntsiab lus tsis tshua muaj carbon, nws cov corrosion kuj thiab weldability zoo dua li cov martensitic stainless hlau zoo tib yam. Cov hlau no muaj cov kua qaub zoo, muaj peev xwm txiav tau zoo, thiab cov txheej txheem kho cua sov yooj yim. Muaj kev nyiam rau embrittlement thaum siv rau lub sijhawm ntev ntawm qhov kub siab tshaj 400 degrees Celsius

• SUS630 Khoom siv:

SUS630 yog tsim los ua cov khoom siv nrog kev ua haujlwm kub hauv qab 400 degrees Celsius, xav tau cov kua qaub tiv thaiv thiab lub zog siab; Nws kuj tseem tsim nyog rau kev tsim cov pwm yas uas xav tau kev ua haujlwm siab thiab kev ua tiav raws li qhov kev txiav txim ntawm corrosive media.
Qhov sib txawv loj tshaj plaws ntawm ob hom hlau yog qhov microstructure ntawm SUS630 thiab SUS316 yog qhov sib txawv, thiab qhov sib txawv ntawm cov khoom siv tshuab yog qhov yooj yim tshaj plaws.

630 stainless hlau yog precipitated, quenched, martensitic stainless hlau nrog siab zog, hardness, thiab corrosion kuj yam ntxwv. Tom qab kev kho cua sov, cov khoom siv kho tshuab ntawm cov khoom tau txhim kho ntxiv, ncav cuag lub zog compressive txog li 1100-1300 mpa (160-190 ksi). Qib no siv tsis tau ntawm qhov kub siab tshaj 300 degree (570F) lossis qis heev. Nws muaj corrosion kuj zoo rau cov cua thiab diluted acids los yog ntsev, thiab nws cov corrosion kuj yog tib yam li 304 thiab 430.

316 stainless hlau, 18Cr-12Ni-2.5Mo, vim qhov sib ntxiv ntawm Mo, muaj kev tiv thaiv corrosion zoo heev, atmospheric corrosion kuj, thiab kub-kub lub zog, thiab tuaj yeem siv nyob rau hauv hnyav hnyav; Zoo heev ua hauj lwm hardening (tsis magnetic). Cov khoom siv hauv dej hiav txwv, tshuaj lom neeg, tshuaj pleev ib ce, papermaking, oxalic acid, chiv thiab lwm yam khoom siv ntau lawm; Kev yees duab, khoom noj khoom haus kev lag luam, chaw ntug hiav txwv dej, hlua, CD ncej, bolts, ceev. Cov tshuaj muaj pes tsawg leeg ntawm 316 stainless hlau: C Tsawg dua lossis sib npaug rau 0.08, Si Less dua lossis sib npaug rau 1.{{10}}, Mn Tsawg dua lossis sib npaug rau 2. 16.0-18.5, Mo: 2.0-3.0. Mechanical zog ntawm 316 stainless hlau, tensile zog (Mpa) 620 MIN, yield zog (Mpa) 310 MIN, elongation (%) 30 MIN, cheeb tsam txo (%) 40 MIN, ceev ntawm 316 stainless hlau 8.03 g / cm3.
