Titanium Beta-C Springs

Titanium Beta-C AMS 4957 alloy has a high level of corrosion resistance due to the existence of a consistent and continuous oxide layer which is formed spontaneously upon exposure to oxygen. Because of the high corrosion resistance, Titanium Beta-C springs can be used for subsea oil & gas applications.

Titanium Beta-C alloy has 4 % of molybdenum which makes it excellent resistance to corrosion in reducing environments such as Hydrogen Sulfide (H2S).
