iStainless Steel 304 1.4301

Insimbi engenasici i-304 kunye ne-stainless steel 304L zikwabizwa ngokuba yi-1.4301 kunye ne-1.4307 ngokulandelanayo. Uhlobo lwe-304 yeyona nto isebenzayo kwaye isetyenziswa ngokubanzi insimbi engenasici. Ngamanye amaxesha kubhekiselwa kuyo ngegama layo elidala elithi 18/8 elithatyathwe kulwakhiwo lwegama lohlobo lwama-304 oluyi-18% yechromium kunye ne-8% nickel. Uhlobo lwe-304 yensimbi engenasici yinqanaba le-austenitic elinokutsalwa ngokunzulu kakhulu. Lo mhlaba ukhokelele ekubeni i-304 ibe lelona bakala lisetyenziswa kakhulu kwizicelo ezifana neesinki neepani. Uhlobo lwe-304L yinguqulo yekhabhoni ephantsi ye-304. Isetyenziswe kumacandelo e-gauge enzima yokuphucula i-weldability. Ezinye iimveliso ezifana neepleyiti kunye nemibhobho zinokufumaneka njengezinto "eziqinisekisiweyo ezimbini" ezihlangabezana nemilinganiselo ye-304 kunye ne-304L. I-304H, i-carbon content variant, iyafumaneka ukuze isetyenziswe kumaqondo aphezulu. Iipropati ezinikwe kolu xwebhu lwedatha ziqhelekile kwiimveliso eziqengqeleke umcaba ezigqunywe yi-ASTM A240/A240M. Kunengqiqo ukulindela ukuba iinkcukacha zale migangatho zifane kodwa zingafane zifane nezo zinikwe kolu xwebhu lwedatha.

Ukutyunjwa kwe-alloy

I-Stainless steel grade 1.4301/304 nayo ihambelana ne: S30400, 304S15, 304S16, 304S31 kunye ne-EN58E.

Ukunyangwa kokuMhlwa

I-304 inokumelana nokugqwesa okugqwesileyo kwimo ye-May kwaye xa inxibelelana nemithombo yeendaba eyonakalisayo. Ukurhawuka komngxuma kunye nemingxuma kungenzeka kwiindawo ezinekloridi. Ukuqhekeka komhlwa woxinzelelo kunokwenzeka ngaphezulu kwama-60°C.

Ukumelana nobushushu

I-304 inokuxhathisa okulungileyo kwi-oxidation kwinkonzo yesikhashana ukuya kuma-870 ° C kunye nenkonzo eqhubekayo ukuya kuma-925 ° C. Nangona kunjalo, ukusetyenziswa okuqhubekayo kwi-425-860 ° C akukhuthazwa. Kulo mzekelo i-304L iyacetyiswa ngenxa yokuchasana nemvula ye-carbide. Apho kufuneka amandla aphezulu kumaqondo obushushu angaphezu kwama-500°C ukuya kutsho kuma-800°C ibakala 304H kuyacetyiswa. Esi sixhobo siya kugcina ukuxhathisa ukubola kwamanzi.

Ukwenziwa

Ukuqulunqwa kwazo zonke iintsimbi ezingenasici kufuneka kwenziwe kuphela kunye nezixhobo ezinikezelwe kwizinto zensimbi ezingenasici. Izixhobo zokusebenza kunye neendawo zokusebenza kufuneka zicocwe kakuhle phambi kokusetyenziswa. Ezi zilumkiso ziyimfuneko ukuze kuthintelwe ukungcoliseka okunqamlezileyo kwentsimbi engatyiwayo ngentsimbi evuthelwe lula enokuthi itshintshe umbala wemveliso eyenziweyo.

Ukusebenza Okubandayo

I-304 yentsimbi engatyiwayo isebenza ngokukhawuleza. Iindlela zokuyila ezibandakanya ukusebenza okubandayo kunokufuna inqanaba eliphakathi lokuthomalalisa ukunciphisa ukuqina komsebenzi kunye nokuphepha ukukrazula okanye ukuqhekeka. Ekugqityweni kolwakhiwo kufuneka kuqeshwe umsebenzi ogcweleyo wokuthomalalisa ukunciphisa uxinzelelo lwangaphakathi kunye nokwandisa ukumelana nomhlwa.

Ukusebenza okushushu

Iindlela zokwenza izinto ezifana nokubumba, okubandakanya ukusebenza okushushu kufuneka kwenzeke emva kokufudumeza okufanayo ukuya kwi-1149-1260 ° C. Amalungu enziweyo kufuneka apholiswe ngokukhawuleza ukuqinisekisa ukuxhathisa ukudleka okukhulu.

Ubuchule

I-304 inobuchule obuhle. Umatshini unokwandiswa ngokusebenzisa le migaqo ilandelayo: Imiphetho yokusika kufuneka igcinwe ibukhali. Imiphetho ebuthuntu ibangela ukuba umsebenzi ube nzima. Ukusikwa kufuneka kube khaphukhaphu kodwa kunzulu ngokwaneleyo ukuthintela ukuqina komsebenzi ngokukhwela kumphezulu wezinto. Iziqhekeza zetshiphu kufuneka ziqeshwe ukunceda ekuqinisekiseni ukuba i-swarf ihlala icacile emsebenzini. I-conductivity ephantsi ye-thermal ye-alloys ye-austenitic iphumela ekugxininiseni ukushisa kwiindawo zokusika. Oku kuthetha ukuba izinto zokupholisa kunye nezithambiso ziyimfuneko kwaye kufuneka zisetyenziswe ngobuninzi.

Unyango lobushushu

I-304 insimbi engenasici ayinakwenziwa lukhuni ngonyango lobushushu. Unyango lwesisombululo okanye ukufakwa kwe-annealing kunokwenziwa ngokupholisa ngokukhawuleza emva kokufudumeza ukuya kwi-1010- 1120°C.

Ukuweldability

Ukusebenza kwe-Fusion welding yohlobo lwe-304 yensimbi engenasici igqwesileyo zombini kunye nangaphandle kwezihluzi. Iintonga zokuzalisa ezicetyiswayo kunye ne-electrode yensimbi engenasici i-304 yinqanaba le-308 yensimbi engenasici. Kwi-304L isigcwalisi esicetyiswayo yi-308L. Amacandelo adityanisiweyo anzima anokufuna ukukhutshwa kwe-post-weld. Eli nyathelo alifuneki kwi-304L. IBakala 321 linokusetyenziswa ukuba unyango lokufudumala emva kwe-weld alunakwenzeka.
