IIMPAWU ZE-SMO 254
Ezi mveliso ziqhuba kakuhle kwizisombululo ze-halide ezine-chloride kunye ne-bromide ion ezikhoyo. Umgangatho we-SMO 254 ubonisa imiphumo ye-corrosion yendawo ebangelwa yi-pitting, imingxuma kunye noxinzelelo. I-SMO 254 yimathiriyeli ye-carbon ephantsi. Ngenxa yomxholo wekhabhoni ephantsi kukho ithuba elincitshisiweyo lemvula ye-carbide ngexesha lokusetyenziswa kobushushu ngexesha le-welding.

UKUSEBENZA
Ngenxa yezinga eliphezulu lokuqiniswa komsebenzi kunye nokungabikho kwesalfure, i-SMO 254 insimbi engenasici kunzima ukuyilungisa; nangona kunjalo, izixhobo ezibukhali, oomatshini abanamandla, ukutya okulungileyo kunye nesixa esikhulu sokuthanjiswa kunye nezantya ezicothayo zidla ngokunika iziphumo ezilungileyo.

UKUSHISA
I-Welding ye-stainless steel grade 254 SMO ifuna ukusetyenziswa kweentsimbi zokuzalisa ezikhokelela kwiipropati ezingaphantsi kwe-tensile. I-AWS A5.14 ERNiCrMo-3 kunye ne-alloy 625 zivunyiwe njengezinyithi zokuzalisa. Ii-electrodes ezisetyenziswa kwinkqubo kufuneka zihambelane ne-AWS A5.11 ENiCrMo-12.

ISIHLOMELO
Ukushisa kwe-annealing kwesi sixhobo kufuneka kube yi-1149-1204 ° C (2100-2200 ° F) elandelwa kukucima kwamanzi.

UKUSEBENZA KWIIMEKO EZIPHELELEYO
Ukuqulunqa, ukuphazamisa kunye neminye imisebenzi kule nto inokwenziwa kwiqondo lokushisa kwi-982-1149 ° C (1800-2100 ° F). Amaqondo obushushu ngaphezu kolu luhlu alukhuthazwa njengoko luya kubangela ukulinganisa kunye nokunciphisa ukusebenza kwezinto. Unyango olushushu lwe-weld luyacetyiswa ukubuyisela ukuxhathisa okukhulu kokuhlwa.

UKWENZA KUBANDA
Ukubunjwa okubandayo kunokuqhutywa nayiphi na indlela eqhelekileyo, kodwa inkqubo iya kuba nzima ngenxa yezinga eliphezulu lokuqina komsebenzi. Ngenxa yoko, izinto eziphathekayo ziya kuba namandla amakhulu kunye nokuqina.

UQINISEKISO
Ukunyangwa kobushushu akuchaphazeli i-stainless steel grade 254 SMO. Ukunciphisa kuphela okubandayo kuya kuvumela ukuqina.
