Dab tsi yog qhov txawv ntawm 1.4541 thiab 1.4301 khoom?

1.4301 Stainless hlau yog dab tsi?

1.4301 stainless hlau yog austenitic, chromium-nickel stainless hlau, tseem hu ua AISI 304 lossis V2A. Nws yog cov khoom siv ntau yam thiab siv dav vim nws zoo heev corrosion thiab kub tsis kam, zoo formability, thiab weldability. Qhov no ua rau nws tsim nyog rau ntau yam kev siv, los ntawm cov khoom siv hauv tsev xws li cutlery thiab dab dej rau cov khoom siv, architecture, thiab cov cuab yeej kho mob.

 

1.4541 Stainless hlau yog dab tsi?

TS EN 1.4541, tseem hu ua X6CrNiTi18-10 lossis AISI 321, yog titanium-stabilized austenitic stainless hlau. Nws yog tsim los muab kev zoo dua intergranular corrosion kuj thaum lub sij hawm thiab tom qab vuam, tshwj xeeb tshaj yog nyob rau hauv siab kub. Qhov sib ntxiv ntawm titanium (Ti Ntau dua lossis sib npaug li 5 × C) khi cov pa roj carbon thiab tiv thaiv chromium carbide nag lossis daus.

 

Cov khoom siv dab tsi yog 1.4301 sib npaug rau stainless hlau?

Khoom siv 1.4541 yog sib npaug rau AISI 321 stainless hlau. Nws yog titanium-stabilized austenitic stainless hlau nrog zoo heev tsis kam mus rau intergranular corrosion, zoo siab - kub lub zog, thiab zoo oxidation kuj. Yog li ntawd, nws yog ib qho tsim nyog lwm txoj rau 304 qib stainless hlau thaum post-weld annealing tsis tau lossis daim ntawv thov kub ntawm 425-900℃.

Dab tsi yog qhov txawv ntawm 1.4541 thiab 1.4301 khoom?

Qhov sib txawv tseem ceeb yog tias 1.4541 (AISI 321) yog titanium -stabilized stainless hlau, thaum 1.4301 (AISI 304) tsis yog. Qhov no ua rau 1.4541 tiv taus ntau dua rau intergranular corrosion tom qab vuam lossis kub kub vim tias titanium khi nrog carbon, tiv thaiv kev tsim ntawm chromium carbides. Raws li qhov tshwm sim, 1.4541 yog qhov zoo dua rau cov qauv welded thiab cov ntawv thov uas muaj qhov kub thiab txias, thaum 1.4301 yog ib qho dav dav -lub hom phiaj steel rau qis- qhov kub thiab txias.

 

1.4307 SS tuaj yeem hloov 1.451 stainless hlau?
1.4307 (304L) yog ib qho qis- carbon stainless hlau uas tau hloov pauv ntau ntawm 1.4541 (321) vim nws qhov sib piv tsis kam rau intergranular corrosion, txhim kho machinability vim tsis muaj titanium, superior nto tiav, thiab txhim kho weldability.
