Nickel 200 & 201 Pipe, Valves, Fittings & Flanges
U. S. Metals diverse inventory offers a full range of Nickel 200 / 201 Pipe, Valves, Fittings & Flanges that is prominent in the process industry. Our support of the power & process industry is reflected in the specialty grades of material that we inventory to support outage & maintenance requirements.
Nickel 200 is commercially pure (99.0%) nickel that is highly resistant to corrosion in many environments. It is a proven product for use in plant processes having exposure to caustic soda, other alkalies and anhydrous hydrofluoric acid. Phenol is commonly stored in Nickel 200 clad steel tanks.
The chemistry of Nickel 201 is identical to Nickel 200 except for the carbon content. Nickel 200 has a maximum carbon content of 0.15%. Nickel 201 limits carbon content to 0.02%. This makes Nickel 201 a more acceptable material in the same type of environments when temperatures are above 600 degrees F.
Our ability to provide Nickel 200 / 201 products on a project basis is one of our strongest capabilities and is unmatched in our industry.
Turnarounds or outages, planned retrofits or emergency situations, grassroots projects worldwide; U.S. Metals has the experienced staff to assist you on all of your specialty alloy requirements, no matter how detailed the specification, no matter how difficult the situation.
New industry requirements, not an issue. We work closely with agencies like EPRI along with our utility and refining clients to be on the cutting edge of new industry requirements that affect your high energy/high temperature piping systems.
Our inventory is evolving to meet the new specifications that prevent current issues as creep cracking and hardness problems.

CR = Corrosion resistant in acordance with MSS SP-43
Nickel Alloy Specifications especially in pipe and tube refer only to the UNS number for material identification. Classes and Grades are occasionally used to identify options for items such as NDT, heat treatment or different methods employed when welding with filler metal such as single welded or double welded. These options do not result in an additional UNS number in the nickel materials.
Grades/Classes/Identification Symbols are shown in this table only when they are used for material identification.
When availability of starting material is a problem, some manufacturers will offer valves machined from Nickel 200 and 201. Customer approval may be required.
Data in this table (except for Valve Castings) was taken from the 2013 editions, Section One Volume 01.01 and Section Two Volume 02.04, of the annual book of ASTM Standards. Casting Specification Data was from Volume 01.02, same edition.
