The microstructure of cold hardened nickel alloys plays an important role in toughness, corrosion resistance, and environmental cracking resistance. The microstructure plays a much lesser role in strength and ductility, which are more directly related to the cold work imparted. The manufacturing of cold hardened tubulars begins with an as-cast ingot of the required chemical […]
While duplex stainless steels, austenitic stainless steels, and nickel-based alloys are naturally resistant to atmospheric corrosion in most industrial environments, improper handling of these alloys may result in compromised material performance. Without special care, corrosion may result from surface damage or contact that often occurs during storage or transportation.
Corrosion resistant alloys are metals engineered to resist degradation by oxidation or other chemical reactions. The most common cra’s, used for mild to moderate corrosion resistance, are stainless steels. Stainless steels are iron-based alloys containing a minimum of 10.5% chromium, which is sufficient to prevent rust under typical room temperature atmospheric conditions. Stainless steels simply […]
