Ngowuphi umgangatho owenziwa yiChina 420 yephepha lensimbi engenasici?

420 ipleyiti yensimbi engenasiciyeye-martensitic steel stainless, enokumelana nokunxiba kunye nokumelana nokugqwala, ubunzima obuphezulu, kwaye ixabiso lisezantsi kunezinye iimpawu zentsimbi.I-420 yensimbi engenasici ifanelekile kuzo zonke iintlobo zoomatshini bokuchaneka, iibheringi, izixhobo zombane, izixhobo, izixhobo, iimitha, izithuthi, izixhobo zendlu, njl. amanzi kunye ne-oxidative acid corrosion.

China 420 intsimbi yesigqeba sokulawula umgangatho:

I-GB/T 3280-2015 “Ishiti leNtsimbi eliQoqiweyo elibandayo eliQhelekileyo kunye ne-Strip”

I-GB/T 4237-2015 "Intsimbi yentsimbi eshushu eqengqelekayo kunye nomtya"

I-GB / T 20878-2007 "Insimbi engenasici kunye nemigangatho yentsimbi ekwazi ukumelana nobushushu kunye nokwakheka kweekhemikhali"

Ipleyiti yentsimbi engama-420 eTshayina:

Amabanga amatsha: 20Cr13, 30Cr13, 40Cr13.

Amabanga amadala: 2Cr13, 3Cr13, 4Cr13.

Iimpawu kunye nokusetyenziswa China 420 sheet steel stainless:

I-20Cr13 insimbi engenasici: ukuqina okuphezulu kwimeko yokucima, ukuxhathisa okulungileyo kokubola.Kwiincakuba zeinjini yomphunga.

I-30Cr13 insimbi engenasici: Inzima kune-20Cr13 emva kokucima, isetyenziswe njengezixhobo zokusika, i-nozzles, izihlalo ze-valve, i-valve, njl.

I-40Cr13 insimbi engenasici: Inzima kune-30Cr13 emva kokucima, isetyenziswe njengezixhobo zokusika, ii-nozzles, izihlalo zevalve, iivalve, njl.
