FAQ:

 

Q: Dab tsi cov qauv tswj kev tsim cov hlau S320GD?

A: Kev tsim khoom ntawm S320GD steel yog tswj los ntawm cov qauv xws li EN 10147, uas qhia meej cov tshuaj muaj pes tsawg leeg, cov khoom siv kho tshuab, thiab txheej txheej kom ntseeg tau zoo thiab ua haujlwm zoo.

Q: S320GD steel puas siv tau rau kev siv vuam?

A: Yog, S320GD steel muaj qhov zoo weldability, ua rau nws tsim nyog rau ntau yam kev siv vuam hauv kev tsim kho thiab tsim khoom. Nws qis - cov ntsiab lus carbon thiab cov ntsiab lus alloying tshwj xeeb pab cov txheej txheem vuam.

Q: Dab tsi yog qhov tseem ceeb ntawm cov lus ntev thiab cov coil hauv kev sib raug zoo rau S320GD steel?

A: Longitudinal yog hais txog kev taw qhia ntawm steel grain qauv, uas tuaj yeem cuam tshuam nws cov khoom siv kho tshuab. Coils qhia txog daim ntawv uas cov hlau tau muab, tso cai rau kev thauj mus los thiab kev ua haujlwm hauv kev tsim khoom.

Q: Cov khoom siv hauv paus ntawm S320GD steel pab tau li cas rau nws cov yam ntxwv?

A: Cov khoom siv hauv paus ntawm S320GD steel, feem ntau yog qis - carbon steel, sib npaug zog thiab ductility. Qhov no ua rau nws zoo tagnrho rau kev tsim thiab tsim cov txheej txheem thaum tuav cov txheej txheem kev ncaj ncees.

Q: Dab tsi yog manganese ua si hauv S320GD steel?

A: Manganese yog ib qho tseem ceeb alloying khoom nyob rau hauv S320GD steel, pab txhawb rau nws lub zog thiab toughness. Nws kuj pab nyob rau hauv cov hlau lub peev xwm mus rau undergo cov txheej txheem annealing, txhim kho nws tag nrho cov neeg kho tshuab zog.
