TITANIUM GRADE 2 SHEET AND PLATE
Titanium Grade 2 is a commercially pure form of titanium. It is widely used because it combines excellent formability and moderate strength with superior corrosion resistance. This combination of properties makes Grade 2 titanium (ASTM B265, AMS 4902, UNS R50400) ideal for a large variety of chemical and marine as well as aerospace and medical applications.

AMS 4902 is a Titanium Grade 2 sheet and plate variation. This is an aerospace material specification known as AMS 4902. The combination of strength and fatigue resistance of this material makes it popular for use in the aerospace industry.
AMS 4902 offers several key benefits:
- Has a high strength to weight ratio, good for aircraft structures.
- Fatigue resistance is good, vital in components which are subjected to repeated stress
- Allows for easier fabrication of complex parts that have good machinability
- Enhancing safety in aerospace applications based on superior damage tolerance
- The strict AMS standards offer consistent and reliable performance of all packages.
- Widely available and familiar within the aerospace industry.
AMS 4902 does not rust in the traditional sense as rusting is a term which is specifically used for the corrosion of iron and steel. Although, Titanium variations including AMS 4902 can corrode under certain conditions. Although AMS 4902 has excellent corrosion resistance for many metals, it is not as corrosion resistant as compared to other alloys.
AMS 4902 is susceptible to pitting and intergranular corrosion especially in environments with high chloride content (i.e. marine atmospheres). However, to counter this the material is often treated in other ways such as anodising or alclad coating to give additional corrosion protection in aerospace use.
