Chrome Moly Welded Pipe

Chrome Moly Pipe is often used in the power generation industry and the petrochemical industry.   It offers high tensile strength, corrosion resistance and high-temperature strength at cost effective prices.   Chrome Moly (also known as chromoly, chrome-moly, CrMo, CRMO, and CR-MOLY) is a ferritic alloy that is creep and heat resistant. It also has a high strength to weight ratio,  which enables designers to use thinner wall pipe or smaller diameter tubing to reduce overall weight.

Penn Stainless also provides a variety of Processing Services and Testing Services for Chrome Moly pipe. Many services are performed in-house, allowing for both improved products and reduced delivery times.

Chome Moly Grades for Custom Welded Pipe Orders

Chrome Moly Grades

P5

Chrome Moly grade P5 is intended for high temperature and high pressure services. It is often used in the power generation industry and the petro-chemical industry because of its tensile strength, corrosion resistance and high-temperature strength. More Info Get a Quote

P9

Chrome Moly P9  stainless is designed for high temperature and pressure services. This grade is used in the power generation industry and the petro-chemical industry because of its tensile strength, corrosion resistance and high-temperature strength, however, it is less common than P5. More Info Get a Quote

P11

Chrome Moly P11 stainless is highly resistant to cracking from hydrogen attack, as well as hot sulfide corrosion cracking. Chrome Moly P11 has a better overall strength to weight ratio than steel, which allows for reduced weight and thinner walls in Chrome Moly products. More Info Get a Quote

P22

Chrome Moly P22 is used in the power generation industry, the petro-chemical industry, the petroleum industry, and in high temperature applications because of its tensile strength, corrosion resistance and high-temperature strength.  More Info Get a Quote

P91

This grade of steel has strong resistance to rupturing and high pressures and/or temperatures, and is commonly used for high temperature and pressure services.  Chrome Moly P91 is prominent in the power generation industry due to its tensile strength, corrosion resistance and high-temperature strength.
