Ukuqulunqwa kweBakala 310/310S iNtsimbi eNgatyiwayo
IFabrication Grades 310/310S yenziwe ngenkohliso kwiqondo lobushushu obuyi-975 – 1175°C.Umsebenzi onzima wenziwa ukuya kuthi ga kwi-1050 ° Can isiphelo sokukhanya sisetyenziswe phantsi koluhlu.Emva kokwenza i-annealing kuyacetyiswa ukuba ukhulule lonke uxinzelelo kwinkqubo yokubumba.Ii-alloys zinokubanda ngokulula zenziwe ngeendlela eziqhelekileyo kunye nezixhobo.
Ubutshixo beBanga le-310/310S iNtsimbi engatyiwayo
I-Machinability Grades 310 / 310SS ifana ne-machinability yohlobo lwe-304. Ukuqina komsebenzi kunokuba yingxaki kwaye kuyinto eqhelekileyo ukususa umsebenzi owenziwe lukhuni ngokusebenzisa isantya esicothayo kunye nokusikeka okunzima, kunye nezixhobo ezibukhali kunye nokuthambisa okulungileyo.Kusetyenziswa oomatshini abanamandla kunye nezixhobo ezinzima neziqinileyo.
Welding of Grade 310/310S Stainless Steel
I-Welding Grades 310/310S idityaniswe nge-electrode ehambelanayo kunye neentsimbi zokuzalisa.I-alloys idityaniswe ngokukhawuleza yi-SMAW (manual), i-GMAW (MIG), i-GTAW (TIG) kunye ne-SAW.I-Electrodes ukuya kwi-AWS A5.4 E310-XX kunye ne-A 5.22 E310T-X, kunye ne-filler metal AWS A5.9 ER310 isetyenziswa.IArgon ikhusela igesi.Ukushisa kwangaphambili kunye nobushushu besithuba akufuneki, kodwa kwinkonzo yokubola kulwelo olugcweleyo lwesisombululo se-annealing unyango oluyimfuneko.Ukuchongwa kunye nokunyanzeliswa komphezulu ukususa iioksidi zobushushu obuphezulu kubalulekile ukubuyisela ukuxhathisa okugcweleyo kokutya okumanzi emva kwe-welding.Olu nyango alufunwa kwinkonzo yokushisa okuphezulu, kodwa i-welding slag kufuneka isuswe ngokupheleleyo.
Ukunyangwa koBubushushu kwiBanga lama-310/310S iNtsimbi eNgatyiwayo
Uhlobo loNyango lwe-Heat 310/310S sisisombululo esifakwe ngokufudumeza kuluhlu lweqondo lobushushu 1040 -1065 ° C, lubambe kwiqondo lobushushu de lufakwe ngokupheleleyo, emva koko lucime amanzi.
Ukumelana nobushushu kwiBanga le-310/310S iNtsimbi eNgatyiwayo
AmaBanga 310 / 310S anokumelana kakuhle ne-oxidation kwinkonzo ephazamisayo emoyeni ukuya kwi-1035 ° Cand 1050 ° Cin inkonzo eqhubekayo.Amabakala axhathisa kwi-oxidation, i-sulphidation kunye ne-carburisation.
Iifom ezifumanekayo zeBakala 310/310S iStainless Steel
I-Austral Wright Metals inokubonelela la mabanga njengepleyiti, ishiti kunye nestriphu, ibha kunye nentonga, ityhubhu engenamthungo kunye nombhobho, ityhubhu edityanisiweyo kunye nombhobho, i-forging billet, iityhubhu kunye nokufakwa kwemibhobho, ucingo.I-Corrosion Resistance Grade 310/310S ayidli ngokusetyenziswa kwinkonzo yolwelo edlekayo, nangona ichromium ephezulu kunye nomxholo wenickel unika uxhathiso ku-corrosion ngaphezu kwebanga lama-304. Ialloyi ayinayo i-molybdenum, ngoko ke ukunganyangeki komngxuma kumbi kakhulu.IBakala 310/310S liya kwaziswa kwi-corrosion ye-intergranular emva kwenkonzo kumaqondo obushushu aphakathi kwama-550 – 800°C.Ukuqhekeka kwe-Chloride stress corrosion kungenzeka kulwelo oludlekayo olunekloridi kumaqondo obushushu angaphezulu kwe-100°C.
