This specific foil is a marvel of modern metallurgy, blending a near-equal mix of austenite and ferrite crystals. Its composition, rich in chromium, nickel, molybdenum, and nitrogen, gives it an exceptional combination of high strength and impressive toughness. This balance means it resists stress corrosion cracking beautifully, while also offering outstanding resistance to pitting and crevice corrosion, making it significantly stronger than standard stainless steels.
