321 ibyuma bidafite ingese

Icyiciro cya 321 na 347 nicyibanze cya austenitis 18/8 ibyuma (Icyiciro cya 304) gihamye na Titanium (321) cyangwa Niobium (347).Aya manota arakoreshwa kubera ko atumva neza kwangirika hagati yimiterere nyuma yo gushyushya mumvura ya karbide ya 425-850 ° C.Icyiciro cya 321 nicyiciro cyo guhitamo kubisabwa mubipimo by'ubushyuhe bugera kuri 900 ° C, bihuza imbaraga nyinshi, kurwanya igipimo no guhagarara kwicyiciro hamwe no kurwanya ruswa nyuma.

Icyiciro cya 321H ni uguhindura 321 hamwe na karubone nyinshi, kugirango itange imbaraga zubushyuhe bwo hejuru.

Intambamyi hamwe na 321 ni uko titanium itimura neza hejuru yubushyuhe bwo hejuru arc, ntabwo rero bisabwa nkugusudira gukoreshwa.Muri iki gihe icyiciro cya 347 kirahitamo - niobium ikora umurimo umwe wo guhagarika karbide ariko irashobora kwimurwa hakurya yo gusudira.Icyiciro cya 347 rero, nibisanzwe bikoreshwa mugusudira 321. Icyiciro cya 347 gikoreshwa rimwe na rimwe nkibikoresho byababyeyi.

Kimwe nandi manota ya austenitis, 321 na 347 bifite imiterere myiza yo gusudira no gusudira, byoroshye gufata feri cyangwa kuzunguruka kandi bifite ibimenyetso byihariye byo gusudira.Annealing ya post-weld ntabwo isabwa.Bafite kandi ubukana buhebuje, ndetse kugeza no ku bushyuhe bwa kirogenike.Icyiciro cya 321 ntigisiga neza, ntabwo rero gisabwa kubishushanyo mbonera.

Icyiciro cya 304L kiraboneka byoroshye muburyo bwinshi bwibicuruzwa, kandi rero mubisanzwe bikoreshwa muguhitamo 321 niba ibisabwa ari ukurwanya ruswa hagati yimitsi nyuma yo gusudira.Nyamara, 304L ifite imbaraga zishyushye ziri munsi ya 321 kandi rero ntabwo aribwo buryo bwiza bwo guhitamo niba ibisabwa ari ukurwanya ibidukikije bikora hejuru ya 500 ° C.

Ibyingenzi

Iyi mitungo isobanutse kubicuruzwa bizengurutse (isahani, urupapuro, na coil) muri ASTM A240 / A240M.Ibintu bisa ariko ntabwo byanze bikunze bisa nkibindi bicuruzwa nka pipe na bar muburyo bwihariye.
