Stainless simbi zvinhu:

Stainless simbi imhando yemhando, ine padyo negirazi kupenya, kubata zvakaoma uye kutonhora, ndeyeimwe avant-garde yekushongedza zvinhu, ine yakanakisa corrosion resistance, kuumba, kugarisana uye kusimba uye humwe hunhu hwakatevedzana, hunoshandiswa muindasitiri inorema. , indasitiri yemwenje, indasitiri yemidziyo yemumba nekushongedza kwezvivakwa nemamwe maindasitiri.

Stainless acid resistant simbi inonzi Stainless steel, inoumbwa nesimbi isina tsvina uye acid isingachinji simbi zvikamu zviviri, muchidimbu, inogona kuramba kupera kwemumhepo yesimbi inonzi Stainless steel, uye inogona kuramba makemikari ari pakati nepakati corrosion yesimbi inonzi acid resistant steel. kutaura, iyo chromium yemukati yeCr yakakura kupfuura 12% yesimbi ine hunhu hwesimbi isina tsvina.

Stainless simbi classification:

Kune nzira dzakawanda dzekugadzirisa simbi isina tsvina, pakati peiyo yakawanda ndiyo inotevera.

Metallographic chimiro kupatsanurwa:

Inogona kukamurwa kuita austenitic Stainless simbi, ferrite Stainless simbi, martensitic Stainless simbi, duplex Stainless simbi, kunaya kwemvura kuomesa simbi isina tsvina.

Chemical composition classification:

Chaizvoizvo inogona kukamurwa kuita chromium Stainless simbi (senge ferrite series, martensite system) uye chromium nickel Stainless simbi (senge austenite system, abnormal series, precipitation hardening series) maviri masisitimu.

Zvinoenderana nerudzi rwe corrosion resistance:

Inogona kupatsanurwa kuita kusagadzikana ngura inodzivirira Stainless simbi, pitting corrosion inodzivirira Stainless simbi, intergranular corrosion inodzivirira Stainless simbi, nezvimwe.

Yakakamurwa ne functional features:

Inogona kukamurwa kuita yemahara yekucheka Stainless simbi, isiri-magnetic Stainless simbi, yakaderera tembiricha Stainless simbi, yakakwirira simba Stainless simbi.

Kune marudzi anoda kusvika zana emasimbi asina tsvina akaiswa mumiyero yakasiyana-siyana munyika, uye nekufambira mberi kwesainzi uye tekinoroji uye kusimukira kweindasitiri nekurima, mamakisi matsva esimbi asina tsvina ari kuwedzerawo.Kune giredhi rinozivikanwa resimbi isina tsvina. , chromium yayo yakaenzana [Cr] uye nickel yakaenzana [Ni] inogona kuverengwa maererano nemakemikari ayo, uye microstructure uye zvinhu zvesimbi zvinogona kufungidzirwa zvakaenzana nekushandisa Schaeffler-Delong simbi isina tsvina microstructure chati.

Matrix classification:

1, ferrite Stainless steel.Chromium 12% ~ 30%.Iyo yekudzivirira kuparara, kusimba uye weldability inowedzera nekuwedzera kwekromium content, uye chloride stress stress corrosion resistance is better pane mamwe marudzi esimbi isina tsvina.

2. Austenitic simbi isina tsvina.Ine zvinopfuura 18% chromium, inenge 8% nickel uye zvishoma zve molybdenum, titanium, nitrogen nezvimwe zvinhu.Kuita kwakanaka kwakazara, kusagadzikana kwehutu kune zvakasiyana-siyana zvemashoko.

3. Austenite-ferrite duplex simbi isina tsvina.Iine zvakanakira austenite uye ferrite simbi isina tsvina, uye ine superplasticity.

Martensitic Stainless simbi.High simba, asi murombo plasticity uye weldability.

Stainless simbi yakajairika simbi nhamba kuenzanisa tafura uye density tafura
