Material Notes:

Ferromagnetic. Allegheny Ludlum AL 201 alloy is wrought commercially pure nickel. This alloy provides highly ductile mechanical properties across a wide temperature range. Either alloy provides corrosion resistance in neutral to moderately reducing environments. In the annealed condition, either alloy possesses the approximate strength of mild steel. As-rolled material is sometimes furnished to provide higher strength levels. Uses include containers and piping in caustic soda and food processing plants.This nickel alloy is readily fabricated by standard fabricating practices. The material are covered by a variety of specification and are assigned maximum allowable stresses in the ASME Boiler and Pressure Vessel Code. This alloy provides high thermal and electrical conductivity in comparison to nickel base alloys, stainless and low alloy steels. AL 201 Alloy is ferromagnetic.Information provided by Allegheny Ludlum
