ZERON 100 (F55 Duplex / 25Cr Duplex) is a super duplex stainless steel for use in aggressive environments. ZERON 100 complies with UNS S32760, however, Rolled Alloys tightly controls the chemistry and production of ZERON 100 in strict accordance with the requirements of our in-house 'MDS' specifications which are tighter than standard ASTM specifications. This ensures a consistent quality product is produced with optimal corrosion resistance and charpy impact toughness

Common Trade Names

Super Duplex Stainless, UNS S32760, F55 Duplex, EN 1.4501, 25Cr Duplex, Super Duplex

Specifications

ASTM A 182, ASTM A 182 (Grade F55), ASTM A 240, ASTM A 276, ASTM A 314, ASTM A 473, ASTM A 479, ASTM A 790, ASTM A 815, NORSOK MDS 055, UNS S32760, W. Nr./EN 1.4501, Werkstoff 1.4501

Its properties include:

Resistant to pitting and crevice corrosion in warm seawater with a guaranteed corrosion performance (PREN > 40)

Lower more stable price compared to nickel based alloys

Excellent resistance to stress corrosion cracking in both chloride and sour environments

Superior resistance to sulfuric acid at most concentrations

Improved resistance over austenitic stainless to erosion corrosion and corrosion fatigue

High Strength (80,000 psi minimum Yield Strength) permitting designs to reduce weight versus other corrosion resistant alloys

ZERON 100 was developed as a seawater resistant material for pump applications in the North Sea as a cast material. Its excellent performance, led to demand for the alloy in a wider range of product forms and the development of wrought product forms. The corrosion resistance and strength properties of ZERON 100 have led to its widespread adoption in a range of industries. Oil and gas applications include process, seawater, firewater and subsea pipework systems, with associated risers, manifolds, pressure vessels, valves and heat exchangers.

Applications

Pollution control equipment such as flue gas desulfurization equipment (FGD), pulp and paper, power generation, chemical, pharmaceutical, desalination, mining, metallurgical and marine industries.

Alloy X is one of the most widely used nickel base super-alloys for gas turbine engine components. This solid solution strengthened grade has good strength and excellent oxidation resistance to 2000°F. Alloy X has excellent resistance to reducing and carburizing atmospheres, making it suitable for furnace components. Due to its high molybdenum content, Alloy X may be subject to catastrophic oxidation at 2200°F. Alloy X is welded by all common methods such as gas tungsten arc, gas metal arc, shielded metal arc, electron beam and resistance welding. Use matching filler metal, keep inter-pass temperature low. After severe forming, fabrications may be annealed 2150°F, 15 minutes per 1/8" of thickness, rapid air cool.

Alloy 20 was designed specifically to withstand sulfuric acid. Its nickel, chromium, molybdenum and copper levels all provide excellent general corrosion resistance. Restricted carbon plus columbium stabilization permits welded fabrications to be used in corrosive environments, normally without post-weld heat treatment. At 33% nickel, Alloy 20 has practical immunity to chloride stress corrosion cracking. This alloy is often chosen to solve SCC problems, which may occur with 316L stainless.
