15-5 ibyuma bidafite ingese ni martensitike, ibintu bikomera imvura hamwe na chromium, nikel n'umuringa. Akenshi ni amahitamo ya mbere mu nganda zo mu kirere kubifata hamwe nibikoresho byubaka. Imiterere yihariye itanga ubukana bwiyongera hamwe no kurwanya ruswa kurusha iyayibanjirije, 17-4 PH. Igenzura ryombi hamwe nubunini bwa delta ferrite ugereranije na 17-4 ibyuma bidafite ingese bigira uruhare runini kuri 15-5. Amavuta akomeza gushimangirwa no kuvura ubushyuhe buke butera umuringa urimo icyiciro muri alloy. 15-5 PH ishoboye guhura nubukanishi bukomeye bukenewe mu kirere no mu nganda za kirimbuzi.
