304 316L 2205 S31803 Simbi Isina Kugadzika
Mharidzo yechigadzirwa:
Kuramba ngura kwesimbi isingasvibi kunonyanya kuenderana nekuumbwa kwayo mu alloy (Cr, Ni, Ti, Si, Al, Mn, nezvimwewo) uye chimiro chayo chemukati.
Zvichienderana nemaitiro ekugadzira ekupisa nekutonhora, mhando mbiri dzesimbi dzakakamurwa kuita zvikamu zvishanu: austenite, austenite-ferrite, ferrite, martensite, precipitation hardening.
Purati resimbi isina ngura rakatsetseka, rine purasitiki yakawanda, kusimba uye simba remuchina, rinodzivirira acid, alkaline gasi, mhinduro nezvimwe zvinhu zvinogadzirwa nesimbi. Isimbi ye alloy isingakanganise ngura.

SA588 SA387 Alloy Steel Plate
Mharidzo yechigadzirwa:
Zvichienderana nezviri mukati me alloy elements, zvinhu zvinotevera zvakakamurwa kuva:
simbi isina alloy yakawanda (huwandu hwese hwezvinhu zve alloy huri pasi pe5%),
Simbi yesimbi ine alloy yepakati (5% -10% yezvinhu zvese zve alloy)
Simbi ine alloy yakawanda (chikamu chose che alloy chakakwirira kupfuura 10%).
Zvichienderana nekuumbwa kwechinhu che alloy mu:
Simbi yeChromium (Cr-Fe-C)
Simbi yeChromium-nickel (Cr-Ni-Fe-C)
Simbi yeManganese (Mn-Fe-C)
Simbi yeSilicon-manganese (Si-Mn-Fe-C)

Ndiro Inodzivirira Kupfekwa, Ndiro Inodzivirira Kutsvuka
Mharidzo yechigadzirwa:
Ndiro yesimbi isingapfeki inoumbwa nezvikamu zviviri: ndiro yesimbi ine kabhoni shoma uye jira risingapfeki re alloy. Rutivi rusingapfeki rwe alloy runowanzova 1/3 ~ 1/2 yeukobvu hwese. Pakushanda, matrix inopa mashandiro akazara akadai sesimba, kusimba uye purasitiki, uye jira risingapfeki re alloy rinopa kuramba kupfeki kuti risangane nezvinodiwa nemamiriro ekushanda akatarwa.
Rutivi runodzivirira kupera kwe alloy runonyanya kuve chromium alloy, uye manganese, molybdenum, niobium, nickel nezvimwe zvikamu zve alloy zvinowedzerwawo. Carbide iri mu metallographic tissue inogoverwa muchimiro che fiber, uye divi re fiber rakamira pamusoro. Kuomarara kwe carbide kunogona kusvika pamusoro pe HV1700-2000, uye kuomarara kwepamusoro kunogona kusvika HRC 58-62. Carbide ye alloy ine kugadzikana kwakasimba pakupisa kwakanyanya, inochengetedza kuomarara kwakanyanya, asi inewo hunhu hwakanaka hwe antioxidant, mukati me500℃ kushandiswa kwakajairika.

S235JR S275JR S355JR Simbi Yekabhoni Plate
Mharidzo yechigadzirwa:
Maplate esimbi akakamurwa kuita maplate akakungurutswa anopisa neanotonhora.
Zvichienderana nemarudzi esimbi, kune simbi yakajairika, simbi yemhando yepamusoro, simbi ye alloy, simbi yechirimo, simbi isina ngura, simbi yezvishandiso, simbi inodzivirira kupisa, simbi ye bearing, simbi ye silicon uye simbi yakachena yeindasitiri.
Simbi yemhando yepamusoro yekabhoni inogona kukamurwa kuita zvikamu zvitatu zvichienderana nehuwandu hwekabhoni hwakasiyana: simbi ine kabhoni shoma (C 0.25%), simbi ine kabhoni yepakati (C i0.25-0.6%) uye simbi ine kabhoni yakawanda (C & gt; 0.6%).
Simbi yemhando yepamusoro yesimbi yekabhoni yakakamurwa kuita manganese yakajairika (0.25% -0.8%) uye manganese yakakwira (0.70% -1.20%), yekupedzisira ine hunhu hwakanaka hwemakanika uye hunhu hwekugadzirisa.
