Type 409 – Most affordable one; used in the automobile industry.
Type 410 – Martensitic (high-strength iron/chromium).
Type 420 – Known as “surgical steel”.
Type 430 – Used in vehicle trims, decorative.
Type 440 – Great cutlery quality, better edge retention due to its high carbon content.
600 Series – Mantensitic precipitation hardening alloys.
Type 630 – Better known as 17-4.
12L14 – Commonly used in automatic screw machines in the production of high number of parts requiring a close tolerance.
Ti-6AI-4V – The most common titanium alloy is the Ti-6AI-4V. It is very resistant to corrosion and extreme temperatures. Great tensile strength and toughness. Highly used by the military, aircraft, spacecraft, and in medical applications.
Typically used in high-temperature applications. Because of work hardening, this metal is very difficult to machine by traditional means.
