I-AISI4130 ASTM 4130 30CrMo SCM430 ipayipi lensimbi elingenamthungo
I-AISI4130 yaseShayina ibanga lasekhaya elingu-30CrMo insimbi eyingxubevange equkethe i-chromium ne-molybdenum, enamandla aqinile ngokuvamile angaphezu kuka-750MPa.Okuvame ukubonakala emakethe amabha namapuleti awugqinsi.Ipayipi lensimbi elinezindonga ezacile elingu-4130 lizosetshenziswa ukwenza Ibhayisikili noma imoto/uhlaka lwebhasi.Lona umhlangano wepayipi lensimbi elikhiphekayo.Yenziwe ngamapayipi ensimbi angenamthungo adonswa abandayo futhi afakwe ngalinye ngalinye ngokuvumelana nengaphakathi lenqola.
Ipayipi lensimbi elingenamthungo le-AISI 4130 linekhono elihle lomsebenzi, ukuwohloka okuncane kokucubungula, nokumelana nokukhathala okuhle kakhulu.Iyingxenye yensimbi enekhono eliqinile eliphakathi nendawo ukuya phezulu.Ngokwelashwa okufanele kokushisa nakho kwenziwa ngomshini kalula.I-Annealing ASTM 4130 alloy steel inikeza i-ductility enhle kakhulu.Insimbi ye-AISI 4130 ivamise ukunikezwa njengebha eyindilinga ngokuvamile esimweni esiqinile nesithambile.

Amapayipi ensimbi angama-4130 avame ukusetshenziswa ezimeni ezicishiwe nezipholile.Uma okuqukethwe kwekhabhoni kusezingeni eliphansi, insimbi ingasetshenziswa futhi njengensimbi ye-carburized edinga amandla aphezulu aphezulu.Embonini yokukhiqiza imishini esezingeni eliphakathi, isetshenziselwa ikakhulukazi ukukhiqiza izingxenye ezicishiwe nezithambile ezinezingxenye ezinkulu eziphambanayo futhi zisebenza ngaphansi kwezimo ezicindezela kakhulu, njengama-shafts, ama-spindles, namasondo okulawula umthwalo omkhulu, amabhawodi, izigxivizo zekhanda eliphindwe kabili, amagiya. , njll;Isetshenziswa embonini yamakhemikhali ukwenza izingxenye ezishiselwe, izakhiwo ezishiselwe ezakhiwe ngamapuleti namashubhu, kanye namapayipi anomfutho ophezulu osebenza ku-nitrogen ne-hydrogen media emazingeni okushisa angeqi ku-250 ° C;Isetshenziselwa ukukhiqiza ama-turbines nama-boilers, ukwenza izinsimbi ezisebenza ngaphansi kuka-450 ° C, ama-flanges nama-flange covers asebenza ngaphansi kwengcindezi ephezulu engaphansi kuka-500 ° C.
Ukuqinisekisa ikhwalithi
1. Iqinile ngokwamazinga Okukhiqiza.
2. Isampula: Isampula limahhala ukuze lihlolwe.
3. Izivivinyo: Ukuhlolwa kwesifutho sikasawoti / Ukuhlolwa kwe-Tensile / Ukuhlolwa kwe-Eddy yamanje / Ukwakheka kwamakhemikhali ngokwesicelo samakhasimende
4.Isitifiketi: IATF16949, ISO9001, SGS njll.
