304/304L Ipayipi Leshubhu Lensimbi Engagqwali

I-ASTM A312 ASTM A269 ASME SA 213 / ASTM A213 TP304, EN 10216-5 1.4301 insimbi engagqwali iwukuhluka kwe-18% chromium – 8% nickel austeniticstainless steel tube, ojwayeleke kakhulu futhi ovame ukusetshenziswa kakhulu emndenini wensimbi engenasici.Le nsimbi engagqwali ibhekwa njengenhlobonhlobo yokusetshenziswa ekumelaneni nokugqwala okuhle, ukwenziwa lula, ukwakheka okuhle kakhulu, namandla aphezulu anesisindo esiphansi.
I-304 Stainless Steel iyinsimbi engagqwali “18/8” ejwayelekile;iyinsimbi engagqwali esebenza ngezindlela eziningi futhi esetshenziswa kabanzi, etholakala ezinhlobonhlobo zemikhiqizo, amafomu kanye nokuqedwa kunanoma iyiphi enye.Inezici ezinhle kakhulu zokwakha kanye ne-welding.Isakhiwo se-austenitic esilinganiselayo seBanga lama-304 siyenza ijule kakhulu ngaphandle kokuhushulwa okuphakathi nendawo, okwenze leli banga libe likhulu ekwakhiweni kwengxenye yensimbi engagqwali edonsayo njengosinki, i-hollow-ware nepani.Kulolu hlelo lokusebenza kuvamile ukusebenzisa okuhlukile okukhethekile kwe-“304DDQ” (Ikhwalithi Yokudweba Okujulile).
IBanga lama-304 libhuleki kalula noma lakhiwe laba izingxenye ezihlukahlukene ukuze lisetshenziswe emkhakheni wezimboni, wezokwakha, nezokuthutha.IBanga lama-304 nalo linesici sokushisela esivelele.I-post-weld annealing ayidingeki lapho ushisela izingxenye ezincane.
IBanga lama-304L, inguqulo yekhabhoni ephansi engu-304, ayidingi ukushiswa kwe-post-weld ngakho-ke isetshenziswa kakhulu engxenyeni ye-heavygauge (ngaphezu kuka-6mm).Ibanga 304H elinokuqukethwe kwekhabhoni ephezulu lithola ukusebenza ezingeni lokushisa eliphakeme.Isakhiwo se-austenitic sinikeza lawa mabanga ukuqina okuhle kakhulu, kuze kufike ku-cryogenictemperature.
