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 maka ịgbado 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-enye ohere ka a kpọọ 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 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.
