◆F51 (31803) bụ ihe a na-ejikarị duplex igwe anaghị agba nchara, tumadi eji na utoojoo mmanụ na gas nke ọma mmepụta, na mmanụ refining, chemical, fatịlaịza, petrochemical na ndị ọzọ ubi, maka imewe nke okpomọkụ Exchangers, condensing coolers, wdg. nke na-adịkarị mfe ikpochapụ corrosion na nrụgide nrụgide nke akụrụngwa nrụgide. Kama 304L, 316L austenitic igwe anaghị agba nchara.

◆F53 (S32750) bụ nnukwu igwe anaghị agba nchara nke nwere nitrogen agbakwunyere, nke a na-ejikarị na kemịkalụ, petrochemical na akụrụngwa mmiri nke chọrọ ike pụrụ iche na nguzogide corrosion.

◆F55 (S32760) bụ nnukwu igwe anaghị agba nchara nwere nnukwu ike, nnukwu iguzogide chloride mpaghara corrosion na corrosion nrụgide, yana weldable.

◆329 (S32900) nwere ezigbo nguzogide oxidation, nguzogide corrosion, ike dị elu, ọ dịkwa mma maka gburugburu ebe obibi dị ka mmiri mmiri na-eguzogide corrosion.

◆A4 ígwè (0Cr17Mn13Mo2N) bụ a dual-phase ígwè, na corrosion eguzogide dị mma karịa nke austenitic ígwè na-ejikarị na-eji Mo ọdịnaya nke 2% -3%. Enwere ike itinye ya na obere fatịlaịza kemịkalụ, akụrụngwa urea okirikiri zuru oke, wdg.

◆S31050 nwere nnukwu iguzogide chloride stress corrosion cracking, magburu onwe iguzogide pitting corrosion na crevice corrosion.

◆U3 nwere mgbochi-scouring na mgbochi corrosion Njirimara, a na-ejikarị eme ka valvụ cores, valvụ oche na ndị ọzọ esịtidem valve components.

◆HD a na-ejikarị na ụlọ ọrụ eletrọnịkị, ụlọ ọrụ fotoelectric, ụlọ ọrụ petrochemical, ụlọ ọrụ ụgbọ ala na nfuli mmanụ ọkụ eletrik ndị ọzọ na-achịkwa ọsọ ọsọ.

◆C4 dabara maka nnukwu igwekota vetikal, igwekota, igwekota, igwekota kwụ ọtọ na ụlọ ọrụ igwe ndị ọzọ.

◆DS-2 nwere nguzogide corrosion na elu okpomọkụ lekwasịrị sulfuric acid, na adabara igwe ụlọ ọrụ na elu okpomọkụ lekwasị sulfuric acid ụlọ ọrụ.
