General Properties

Chrome Moly grade P5 is intended for high temperature and high pressure services.  Chrome Moly P5 is used in the power generation industry and the petro-chemical industry because of its tensile strength, corrosion resistance and high-temperature strength.  Chrome Moly P5 has a better strength to weight ratio than steel, allowing producers to reduce overall weight and create thinner walls. Additionally, this grade shows strong resistance to rupturing at high pressures and/or temperatures.  Lastly, Chrome Moly P5 is very  resistant to cracking from hydrogen attack and hot sulfide corrosion cracking.
