Alloy Steel
Similar to magnesium, nickel is used to increase the strength and toughness of the metal structure. This element is an austenite stabilizer that helps in improving corrosion resistance and oxidizing properties.
Titanium is considered one of the strongest and toughest metals on the earth. Mixing titanium with steel can help you create a standard quality and durable alloy for your construction and other project purposes.
