Puas yog hlau alloy yooj yim rau vuam?

Weldability sib txawv raws qib, carbon sib npaug, qib zog thiab ntu tuab. Ntau qib siab - qib zog xav tau kev tswj hwm preheat, qis -hydrogen xyaum, kev sib cuam tshuam tswj thiab qee zaum tom qab-weld heat treatment. Siv cov txheej txheem vuam tsim nyog rau cov khoom tshwj xeeb thiab kev sib koom ua ke.

Qhov luaj li cas thiab qhov chaw sim ua li cas cuam tshuam rau cov khoom siv kho tshuab?

Cov ntu loj txias qeeb dua thaum kho cua sov, yog li qhov chaw yuav tsis ncav cuag tib lub hardness thiab toughness raws li qhov saum npoo los yog qhov ntsuas me me. Qhia qhov tseeb seem thiab qhov yuav tsum tau kuaj qhov chaw thiab orientation.

Dab tsi cuam tshuam rau tus nqi thiab lub sijhawm ua haujlwm?

Cov tsav tsheb tseem ceeb yog qib, cov khoom tsim, ntu loj, cua sov- txoj kev kho mob, kev txiav txim hnyav, kev siv tshuab ua haujlwm, kev xav tau tshwj xeeb melting, NDT txais, kuaj zaus, tshuaj xyuas cov ntaub ntawv thiab ntim khoom. Lub sijhawm ua haujlwm raug lees paub tom qab kev tshuaj xyuas tiav.

Yuav ua li cas alloy steel tuav thiab forgings ntim rau export?

Kev ntim khoom yuav suav nrog cov pob khoom, kev tiv thaiv kawg, tiv thaiv-cov roj xeb, cov khoom siv VCI, cov khoom sib cais, rooj plaub lossis cov ncej steel. Cov khoom hnyav yuav tsum muaj kev ruaj ntseg thaiv thiab tshem tawm thiab cov cim traceability. Txoj kev kawg yog pom zoo rau cov khoom thiab kev thauj mus los.

Rau qhov hais kom raug, suav nrog cov ntaub ntawv hauv qab no

• Qib qeb thiab tswj tus qauv nrog kev kho dua tshiab

• Cov khoom tsim thiab ua tiav qhov ntev

• Kev xa khoom thiab cua sov-kev kho mob

• Yuav tsum muaj cov khoom siv kho tshuab nrog rau qhov chaw kuaj thiab ntsuas kub

• Surface condition, tolerance and machining allowance

• NDT txoj kev, kev pov hwm thiab kev lees txais

• Ntau, daim hnyav lossis tag nrho qhov hnyav

• Cov ntaub ntawv soj ntsuam thiab thib peb - tog yuav tsum

• Cov txheej txheem ntim khoom, chaw nres nkoj lo lus teb thiab hnub xa khoom xav tau

• Kev kos duab, siv kawg thiab txhua yam kev yuav khoom
