Ku-duplex stainless steel (DSS), isigaba se-austenite kanye nesigaba se-ferrite sithatha cishe uhhafu wesakhiwo sesixazululo esiqinile, futhi sinezici zesakhiwo sezigaba ezimbili.Ayigcini nje ngokugcina izici zensimbi engagqwali ye-ferritic, efana ne-thermal conductivity enkulu, i-coefficient encane yokunwetshwa komugqa, ukumelana nokugqwala kwe-pitting kanye nokugqwala kwe-crevice, nokugqwala kokucindezeleka kwe-chloride, kodwa futhi inokuqina okuhle, izinga lokushisa eliphansi le-brittle transition kanye nokumelana nokugqwala kwe-intergranular. insimbi engagqwali ye-austenitic.Ngokusebenza kahle nezinye izinzuzo, isetshenziswa kabanzi ku-petrochemical, ukuphrinta nokudaya, ubunjiniyela basolwandle, imboni yokudla kanye nezimboni zokwenza amaphepha.
Ngokuthambekela kokukhulisa usayizi wemishini yesimanje yezimboni kanye nokunciphisa izindleko zokukhiqiza, ezinye izingxenye ezinkulu zikhiqizwa kakhulu ngokumbondela izendlalelo zensimbi engagqwali eziyi-duplex ezimelana nokugqwala kuma-substrate ensimbi enengxubevange ephansi.
Inqubo ye-Strip electroslag Surfacing isetshenziswa kabanzi ekukhiqizeni ngenxa yekhwalithi yayo yokushisela ezinzile, izinga eliphezulu lokuzenzakalela, nokusebenza kahle kokukhiqiza okuphezulu.
Ithebula 1 Ukwakheka kweribhoni ye-GDS-2209
Ithebula 2 GDS-2209&GXS-E330 idiphozithi yokwakheka kwensimbi
Ithebula 3 GDS-2209&GXS-E330 ukuhlolwa kokugoba nokumelana nokugqwala
| Izinto zokuhlola | Ububanzi bendololwane 4T 180 ukugoba ohlangothini olusemaceleni | I-GB/T 4334E intergranular corrosion | I-ASTM A923 C (22℃*24H) | I-ferrite elinganiselwe |
| Dinga | Isendlalelo esingaphezulu ≤ 1.5mm isici sokuvula | Ayikho imifantu yokugqwala kwe-intergranular | ≤10 mdd | 35-65% |
| Imiphumela yokuhlolwa | Asikho isici sokuvula | akukho crack | 1.9 mdg | 38.3 |
GDS-2209&GXS-E330 izithombe zobuhlalu bokushisela
I-GB/T 4334.E indlela ye-intergranular corrosion izithombe
Isithombe se-ASTM A923C Intergranular Corrosion Isithombe 4T180 esibheke eceleni esigobe isithombe
Ukusetshenziswa kwensimu kwe-strip surfing welding
Imichilo yensimbi engagqwali eyi-duplex yemikhiqizo engaphezulu eyenziwe yinkampani yethu (i-strip GDS-2209 ene-GXS-E330 flux) inokusebenziseka okuhle kakhulu kokushisela kanye nezakhiwo zomzimba namakhemikhali, ezingahlangabezana nezidingo zokukhiqiza nokukhiqiza.Siyakwamukela ukuze ubuze futhi uthenge.
