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.
