Khoom Taw qhia

AISI SAE 4140 alloy steel yog chromium molybdenum alloy steel specification dav siv nyob rau hauv dav dav lub hom phiaj siab tensile steel rau Cheebtsam, xws li axles, shafts, bolts, zog thiab lwm yam kev siv. Zoo ib yam li alloy qib AISI 4130 chrome moly alloy hlau tab sis nrog cov ntsiab lus carbon ntau dua me ntsis. Cov pa roj carbon ntau dua ntawm AISI 4140 steel muab lub zog ntau dua thiab kev kho cua sov muaj peev xwm sib piv rau AISI / ASTM 4130 alloy steels, txawm li cas los xij nws muaj peev xwm ua haujlwm tsis zoo.

Mechanical Properties

Cov khoom siv tshuab feem ntau suav nrog lub zog tensile, lub zog tawm los, elongation, cheeb tsam lossis txo qis, hardness, cuam tshuam tus nqi, tsis yog xim hlau suav nrog thiab lwm yam. Kev kho cua sov sib txawv, cov khoom siv kho tshuab yuav txawv, xws li normalized, tempered, QT. Yog tias koj xav paub cov khoom, thov hu rau tus neeg muag khoom.

Cov duab ntxaws

Seamless steel kav yog perforated los ntawm ib puag ncig steel, thiab steel kav tsis muaj
welds nyob rau saum npoo yog hu ua seamless steel kav. Raws li txoj kev tsim, seamless steel kav yuav muab faib ua kub dov seamless steel kav, txias dov seamless steel kav, txias-draw seamless steel kav, extruded seamless steel kav, thiab sab saum toj kav. Raws li tus ntoo khaub lig-sectional duab, seamless steel kav muab faib ua ob hom: puag ncig thiab tshwj xeeb-puab. Cov kav dej tshwj xeeb muaj cov square, oval, triangular, hexagonal, melon noob, hnub qub, thiab finned kav. Qhov siab tshaj plaws txoj kab uas hla yog 900 hli thiab qhov tsawg kawg nkaus txoj kab uas hla yog 4 hli. Raws li kev siv sib txawv, muaj tuab-walled seamless steel kav thiab nyias-walled seamless steel kav. Seamless steel kav feem ntau yog siv los ua roj av geological drilling kav, petrochemical cracking kav, boiler kav, bearing kav, thiab high-precision structural steel kav rau tsheb, tsheb laij teb, thiab aviation.
