A steel alloy is created when other metals are added to the basic combination of iron and carbon, improving its properties. Looking for higher strength, corrosion resistance or better response to heat treatment? There's an alloy for that. When the percentage of alloy material is below the level indicated by specialized terms such as "chrome" or "stainless," the product is simply called "alloy steel." 

 

Manufactured to API specification 5CT. This is a controlled yield strength material with a hardness testing requirement. Used in wells with carbon dioxide environments.

Available in casing dimensions of 114.3 mm (4.5") to 339.7 mm (13.38")

Available in tubing dimensions of 60.3 mm (2.38") to 114.3 mm (4.5")
