Nkọwa dị mkpirikpi:
ER 2209Emebere ya iji weld igwe anaghị agba nchara duplex dị ka 2205 (Nọmba UNS N31803).Ike ike dị elu na nkwụsi ike ka mma na mgbawa corrosion na mgbakasị ahụ na-eji mara welds nke waya a.Waya a dị ala na ferrite ma e jiri ya tụnyere nke metal base iji nweta nkwalite weldability.
ER 2553A na-eji ya eme ihe na-agbado igwe anaghị agba nchara duplex nke nwere ihe dịka 25% chromium.Ọ nwere microstructure 'duplex' nke nwere matriks austenite-ferrite.Ihe e ji mara alloy duplex a site na ike dị elu dị elu, nguzogide nrụgide corrosion crack na mma nguzogide pitting.
ER 2594bụ waya ịgbado ọkụ nke superduplex.Nọmba Nguzogide Pitting (PREN) dịkarịa ala 40, si otú a na-ekwe ka a na-akpọ ígwè weld ahụ superduplex igwe anaghị agba nchara.Waya ịgbado ọkụ a na-enye kemịkalụ dabara adaba na njirimara akụrụngwa iji rụọ ọrụ alloys superduplex dị ka 2507 na Zeron 100 yana superduplex casting alloys (ASTM A890).A na-agbado waya ịgbado ọkụ 2-3 pasent na Nickel iji nye oke ferrite/austenite kacha na weld emechara.Ihe owuwu a na-ebute oke tensile na inye ike yana nguzogide dị elu na SCC na corrosion pitting.
