Cov yam ntxwv tseem ceeb ntawm 321/321H Seamless Steel Yeeb Nkab
Kub Kub Resistance: Exhibits oxidation zoo heev thiab scaling kuj ntawm kub txog li 816℃(1500℃F). Qib 321H yog tsim rau kev siv kub ntau dua, feem ntau tshaj 537℃(1000℃F).
Seamless Structure: Seamless steel kav yog tsim los ntawm cov khoom steel hlau tsis muaj welds sab hauv, muab cov qauv zoo tshaj plaws, lub zog, thiab siab - siab tsis kam piv rau welded steel kav.
Corrosion Resistance: Tag nrho cov corrosion kuj yog piv rau 304 stainless hlau, tab sis nws lub ntsiab kom zoo dua nyob rau hauv nws tsis kam mus rau polythiosulfate kev nyuaj siab corrosion cracking thiab intergranular corrosion nyob rau hauv lub siab - kub cuam tshuam cheeb tsam. Nws qhov kev ua tau zoo tsis zoo hauv cov tshuaj chloride lossis sulfuric acid.
Lub cev muaj zog: Tsis yog- sib nqus nyob rau hauv lub xeev annealed thiab tsis tuaj yeem hardened los ntawm kev kho cua sov, tsuas yog ua haujlwm txias.
Kev siv ntau yam ntawm 321/321H Seamless Steel Pipe
Vim nws cov khoom tshwj xeeb, 321/321H seamless steel kav yog feem ntau siv nyob rau hauv hnyav siab - kub ib puag ncig.

FAQ
Q: Qhov txawv ntawm SS 321 thiab 321H yog dab tsi?
A: Qhov sib txawv tseem ceeb ntawm SS 321 thiab 321H nyob hauv lawv cov ntsiab lus carbon: SS 321 muaj cov ntsiab lus siab tshaj plaws ntawm 0.08%, thaum 321H nyob ntawm 0.04% mus rau 0.10%. Lawv cov compositions zoo ib yam.
Q: Dab tsi yog 321 stainless hlau yeeb nkab?
A: 321 stainless hlau yog cov cua sov- cov hlau tsis muaj zog uas paub txog nws qhov zoo heev corrosion kuj thiab siab - kub lub zog. Qhov no austenitic alloy tuav nws qhov toughness thiab tag nrho lub zog txawm tias qhov kub thiab txias, ua rau nws haum rau ntau hom kev siv kub ntawm -.
Q: Hom 321 stainless hlau yog dab tsi?
A: 321 stainless hlau yog titanium -stabilized austenitic stainless hlau, thiab nws cov corrosion kuj zoo ib yam li 304/304L stainless hlau.
