Pitting Resistance Equivalent Number (PREN): How to Compare Duplex & Super Duplex Alloys
When choosing stainless steel for oil and gas, marine, desalination, chemical processing, mining, and offshore applications, pitting corrosion is one of the most significant corrosion problems. The integrity of pipes, fittings, flanges, valves, and other pressure-carrying components may eventually be compromised by localized, hard-to-detect attacks caused by surroundings containing chloride. The Pitting Resistance Equivalent Number […]
ASTM A815 vs ASTM A182: Key Standards for Duplex & Super Duplex Fittings and Flanges
In demanding industries like oil and gas, offshore engineering, desalination, chemical processing, maritime applications, and power generation, duplex and super duplex stainless steels are extensively utilized. These materials combine exceptional resistance to stress corrosion cracking, pitting, crevice corrosion, and corrosion caused by chloride with great mechanical strength. Choosing the right material grade is just one […]
UNS S32760 vs UNS S32750: Is There a Real Difference for Your Project?
Super Duplex stainless steels are now necessary components for demanding applications that call for both remarkable corrosion resistance and excellent mechanical strength. Super duplex grades are widely used for pipes, fittings, flanges, valves, and pressure-containing components in industries like oil and gas, offshore engineering, subsea pipelines, desalination, chemical processing, maritime engineering, and power generation. UNS […]
Super Duplex Steel Fittings for Offshore & Subsea Applications: UNS S32750 & S32760 Guide
In offshore and subsea industries, where pipelines, valves, and process systems must contend with high pressure, corrosive seawater, and challenging environmental conditions, Super Duplex Steel Fittings are frequently utilized. In harsh maritime conditions, grades like UNS S32750 and UNS S32760 are made especially to provide high strength, excellent corrosion resistance, and long-term durability. Super Duplex […]
