I-Grade 310 iyinsimbi engagqwali ye-carbon austenitic ephakathi, yokusetshenziswa kwezinga lokushisa eliphezulu njengezingxenye zesithando somlilo kanye nemishini yokwelapha ukushisa.Isetshenziswa emazingeni okushisa afinyelela ku-1150°C enkonzweni eqhubekayo, kanye no-1035°C enkonzweni yezikhawu.I-Grade 310S inguqulo ye-carbon ephansi yebanga lama-310.
Izicelo ze-Grade 310/310S Stainless Steel

Izicelo Ezijwayelekile zeBanga 310/310S zisetshenziswa kumshini wokubala umbhede one-fluidised, okokhela, amashubhu akhazimulayo, iziphanyeko zamashubhu zokucwenga uphethiloli kanye namabhoyela esitimu, izingxenye zangaphakathi zegesi yamalahle, amabhodwe omthofu, ama-thermowells, amabhawodi ehange aphikisayo, izibasi namakamelo avuthayo, ama-muffles, amakhava e-annealing, ama-saggers, imishini yokucubungula ukudla, izakhiwo ze-cryogenic.

Lawa mabanga aqukethe u-25% we-chromium no-20% we-nickel, okuwenza amelane kakhulu ne-oxidation nokugqwala.I-Grade 310S inguqulo yekhabhoni ephansi, ethambekele kancane ekugxilweni nasekuqwashiseni enkonzweni.I-chromium ephezulu kanye nokuqukethwe kwe-nickel emaphakathi kwenza lezi zinsimbi zikwazi ukusetshenziswa ekunciphiseni i-sulphur atmospheres equkethe i-H2S.Asetshenziswa kakhulu ezindaweni eziphansi ze-carburising, njengoba kutholakala ezindaweni ze-petrochemical.Ukuze uthole izimo ezinzima kakhulu ze-carburising, ezinye izingxube ezimelana nokushisa kufanele zikhethwe.Ibanga 310 alituswa ukuthi licime uketshezi njalo njengoba lihlushwa ukushaqeka okushisayo.Ibanga livame ukusetshenziselwa izinhlelo zokusebenza ze-cryogenic, ngenxa yokuqina kwayo kanye nokufinyeleleka okuphansi kazibuthe.
Ngokufana nezinye izinsimbi ezingenasici ze-austenitic, lawa mabanga awakwazi ukwenziwa lukhuni ukwelashwa okushisa.Zingenziwa lukhuni ngomsebenzi obandayo, kodwa lokhu akuvamile ukwenziwa.
