ALLOY 50 - Austenitic Stainless Steel

 Alloy 50 is a chromium-nickel-manganese-molybdenum austenitic stainless steel that remains completely nonmagnetic after severe cold working or exposure to low temperatures. Its unique feature is the combination of higher strength and better corrosion resistance than the more widely used austenitic stainless grades.

Alloy 50 is considerably stronger than the conventional 300 series stainless steels but the same fabrication equipment and techniques are utilized.

Alloy 50 has superior corrosion resistance almost double the yield strength than Type 304
exceptionally low magnetic permeability, outstanding cryogenic properties and good seawater resistance.

TYPICAL USAGE

Alloy 50 is ideal where 316, 316L, 317 and 317L are marginal. It has found wide use in the petroleum, petrochemical, chemical, pulp and paper, textile, food, nuclear and marine industries.

Marine
seawater pumps, gate valves for seawater ballast systems on tankers, high-pressure (microbial) deep-sea sampler and incubation chambers and underwater robotic arms.

Chemical
urea production, ammonium carbamate pumps, pressure vessels, tanks, heat exchangers, piping, fittings, valves and pumps.

Pump & Paper
Valves for sulfite liquors

Nuclear Waste Disposal
waste calcination systems, aqueous fluoride handling systems and waste canisters.

Oil & Gas Production
oil field production and down-hole equipment

MasterSource stocks alloy 50 inventory as noted below.
