I-304 / 304L yeNsimbi engenamthungo yeTubhing engenamthungo Umfanekiso obonakalayo
  • I-304 / 304L i-Stainless Steel iTubing engenamthungo 1
  • I-304 / 304L i-Stainless Steel iTubing engenamthungo 2

I-304 / 304L i-Stainless Steel seamless Tubing

Inkcazelo emfutshane:

I-304 kunye ne-304L amabakala e-austenitic stainless steel yizona zinto zixhaphakileyo kwaye zisetyenziswa ngokuqhelekileyo iintsimbi ezingenasici. I-304 kunye ne-304L i-stainless steels yinguqu ye-18 yepesenti ye-chromium - i-8 yepesenti ye-nickel austenitic alloy.Babonisa ukuxhathisa okugqwesileyo kwe-corrosion kwiindawo ezininzi ezinobungozi.

Intshayelelo yeMveliso

I-alloys 304 (S30400) kunye ne-304L (S30403) i-stainless steels yinguqu ye-18 yepesenti ye-chromium - i-8 yepesenti ye-nickel austenitic alloy, eyona nto iqhelekileyo kwaye isetyenziswa rhoqo kwintsapho yensimbi engenasici. I-304 / L yensimbi engenasici ineempawu ezintle kakhulu zokwenza. Ubunzima bayo buvumela ukuba yenziwe lula ukuvutha, ukugoba kunye nokujiya. I-machinability elungileyo kunye nomxholo wesulfure ophantsi ukhuthaza ukuqina okugqwesileyo kwizicelo ezifunayo.

Amandla aphezulu, ukumelana nokugqwesa okugqwesileyo kunye nomxholo oncitshisiweyo wekhabhoni wenza i-Alloy 304 kunye ne-304L i-Stainless Steels iluncedo kwizicelo apho kufuneka i-welding. Usetyenziso lubandakanya ukubumba kwezakhiwo kunye ne-trim, amacandelo adityanisiweyo ekhemikhali, amalaphu, amaphepha, izixhobo zokulungisa amayeza kunye neshishini lemichiza.

Ezinye iingenelo kukuchasana kwayo ne-oxidation, ukubunjwa okugqwesileyo, ukukhululeka kobugcisa kunye nokucoca, amandla agqwesileyo kumlinganiselo wesisindo kunye nokuqina okulungileyo kumaqondo okushisa e-cryogenic Kwiindawo ezinobungozi obunzima, umxholo ophantsi we-Type 304L ukhethwa ngenxa yokukhuseleka okukhulu kwi-corrosion intergranular.

Uhlobo lwe-304L yensimbi engenasici yinguqulelo yekhabhoni engaphantsi kwe-304 yentsimbiingxubevange. Umxholo ophantsi wekhabhoni kwi-304L unciphisa i-carbide precipitation enobungozi okanye eyingozi ngenxa ye-welding. I-304L, ke ngoko, ingasetyenziswa "njengoko idityanisiweyo" kwindawo enomhlwa kakhulu, kwaye iyayiphelisa imfuno yokufunxa.

Eli bakala lineempawu zoomatshini ezisezantsi kancinci kunomgangatho oqhelekileyo wama-304, kodwa lisasetyenziswa ngokubanzi enkosi ngenxa yokuguquguquka kwalo. Njengentsimbi ye-Type 304, idla ngokusetyenziswa ekudidiyeleni ibhiya nasekwenzeni iwayini, kodwa nangeenjongo ezingaphaya koshishino lokutya olufana nezikhongozeli zeekhemikhali, imigodi kunye nolwakhiwo. Kukulungele ukusetyenziswa kwiindawo zetsimbi ezifana namantongomane kunye neebholiti ezivezwe kumanzi anetyuwa.
