Imivalo yensimbi engenasici yenziwe kwiingots zetsimbi ezingenasici ezishushu ziqengqiwe okanye zenziwe.

Imivalo yensimbi engenasici idla ngokubonakaliswa ububanzi kwaye inoluhlu olubanzi lwezicelo, kubandakanywa i-petroleum, i-electronics, iikhemikhali, amayeza, amalaphu, ukutya, oomatshini, ukwakhiwa, amandla enyukliya, i-aerospace kunye namashishini omkhosi.

Ubungakanani beentsimbi ezijikelezayo zentsimbi ngokuqhelekileyo zivela kwi-1.0 mm ukuya kwi-250 mm, kwaye inkqubo yokuvelisa inokwahlulwa ibe ziindidi ezintathu: i-hot rolling, forging and cold drawing.

Ngomhla we-15 kaFebruwari, 2024, iKhomishini yoRhwebo yaMazwe ngaMazwe yase-US (USITC) yagqiba ekubeni irhoxise i-odolo ekhoyo echasene nokulahla (AD) ngoyenziwe ngentsimbi eshayinayoimivalo evela eIndiya inokukhokelela ekuqhubekeni okanye ukuphinda kokwenzakala kwezinto kushishino lwase-US ngexesha elibonakalayo.

Ngenxa yoqinisekiso lwe-USITC, umyalelo okhoyo we-AD wokungeniswa kwempahla evela eIndiya uya kugcinwa.

Olu phononongo lokutshona kwelanga luqalwe nge-1 kaSeptemba 2023

imivalo yentsimbi engenasici

Imivalo engqukuva yentsimbi engenastainless ibandakanya kodwa ayiphelelanga kwezi ntlobo zilandelayo:

316L Stainless Steel Round Rod

Le ntsimbi ingenasici iqulethe i-molybdenum kwaye iphantsi kwekhabhoni, inika ukuxhathisa okugqwesileyo kwi-corrosion kwindawo yolwandle kunye neshishini lemichiza.

I-304L intonga ejikelezayo yensimbi engenasici

Njengentsimbi ephantsi kwekhabhoni ye-304, ukuxhathisa kwe-corrosion kufana ne-304. Emva kwe-welding okanye i-stress relief, inokumelana kakuhle ne-intergranular corrosion kwaye inokugcina ukuxhathisa okulungileyo ngaphandle kokunyanga ukushisa.
302 intsimbi engqukuva intonga

Isetyenziswa ngokubanzi kwiindawo zemoto, inqwelomoya, izixhobo zehardware ye-aerospace kunye neshishini lemichiza.

301 intsimbi engqukuva intonga

Ine-ductility elungileyo, ifanelekile kwiimveliso ezibunjiweyo.

200 series steel stainless imivalo ngeenxa zonke

202 imivalo engqukuva yentsimbi engenastainless (ukusebenza ngcono kune-201) kunye ne-201 yeentsimbi ezirawundi zentsimbi engatyiwayo (yeye-chromium-nickel-manganese austenitic steel stainless enemagnetism esezantsi).

400 series steel stainless imivalo ngeenxa zonke

410yenziwe ngentsimbi eshayinayoimivalo engqukuva (intsimbi yechromium eyomelele kakhulu, ukuxhathisa kokunxitywa kakuhle kodwa ukuxhathisa okungekuhle)

Iintsimbi ezijikelezayo ezingama-420 zentsimbi ("ibakala lokusika isixhobo" intsimbi ye-martensitic) kunye ne-430 yentsimbi ejikelezayo imivalo ejikelezayo (intsimbi eqinile yentsimbi yokuhlobisa).

Iintsimbi zensimbi ezingenasici zinokwahlulwa zibe ziindidi ezintathu ngokwetekhnoloji yokuvelisa: ukuqengqeleka okushushu, ukubumba kunye nomzobo obandayo.

Inkcazo yentsimbi eshushu egobileyo imivalo ejikelezayo i-5.5-250 mm

Umahluko phakathi kwemivalo yentsimbi epholileyo eqengqelekayo kunye neentsimbi ezibandayo eziqengqelekayo

Imivalo ejikelezileyo eshushu kunye nebandayo eqengqelekayo ziinkqubo ezimbini ezahlukeneyo zokuvelisa.

Iiyantlukwano ezithile zezi zilandelayo:

Inkqubo yokuvelisa i-hot-rolled stainless steel bars iquka amanyathelo amathathu: ukufudumeza, ukuqengqeleka kunye nokupholisa.

Imivalo engqukuva epholileyo engenastainless ayifuni kufudunyezwa, kodwa kufuneka icocwe kwaye ifakwe.

Umphezulu wentsimbi eshushu eqengqelekayo imivalo engqukuva irhabaxa, inokwakheka kwesinyithi esicacileyo, kwaye inokuba nombala we-oxidation.

Imivalo engqukuva yentsimbi epholileyo eqengqelekayo inomphezulu ogudileyo, akukho mbala ucacileyo we-oxidation, kunye nomgangatho ongcono kunye nenkangeleko.

Imivalo ejikelezileyo yentsimbi eshushu eqengqelekayo inokuqina okuhle kunye ne-ductility, kwaye ifanelekile kwizihlandlo ezifuna ukumelana noxinzelelo olukhulu okanye ukugoba.

Imivalo engqukuva yentsimbi epholileyo eqengqelekayo inobunzima obuphezulu kunye namandla kwaye ifanelekile kwizicelo ezifuna ukumelana nokunxiba okuphezulu kunye nokumelana nomhlwa.

Iintsimbi ezijikelezayo ezishushu ezishushu zisetyenziswa ikakhulu kulwakhiwo, koomatshini, kushishino lweekhemikhali nakwezinye iindawo, njengemibhobho, izikhongozeli, iinxalenye zesakhiwo, njl.

Imivalo ejikelezileyo yentsimbi epholileyo eqengqelekayo isetyenziswa ikakhulu kwizixhobo zasekhaya, iimoto, iimveliso zombane kunye nezinye iindawo, ezinje ngezinto zombane, iinxalenye zemoto, izixhobo zasekhitshini, njl.

Iintsimbi ezishushu ezigoqiweyo kunye nezakhiweyo ezinemilinganiselo (ububanzi, ubude becala, ubukhulu okanye umgama phakathi kwamacala achaseneyo) hayi ngaphezulu kwe-250mm.

Izinto zensimbi ezingenasici: 304, 304L, 321, 316, 316L, 310S, 630, 1Cr13, 2Cr13, 3Cr13, 1Cr17Ni2, intsimbi ye-duplex, insimbi ye-antibacterial kunye nezinye izinto!

Iimpawu zemivalo yensimbi engenasici zidla ngokubonakaliswa ngobubanzi.

Iimpawu eziqhelekileyo zezi: ububanzi 10mm, 12mm, 16mm, 20mm, 25mm, 30mm, 35mm, 40mm, 45mm, 50mm, 55mm, 60mm, 65mm, 70mm, 75mm, 80mm, 85mm, 90mm, 1mm, 1mm 1mm 0mm , 140mm, 150mm, 160mm, 170mm, 180mm, 190mm, 200mm, 220mm, 240mm, 250mm, 260mm, 280mm kunye ne-300mm, njl.
