ALLOY 200 201 DATA SHEET - Jacquet Metal Service

1 1 / 8 For internal use 200 / 201 data SHEETUNS N02200 / UNS N02201//// ALLOY 200 (UNS designation N02200) and ALLOY 201 (UNS designation N02201) are wrought commercially pure nickel. The alloys differ only in the maximum carbon level allowed by specification, % maximum for ALLOY 200 and % maximum for ALLOY 201. Both alloys provide highly ductile mechanical properties over a wide temperature range. Both alloys provide 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 ALLOY 200 and ALLOY 201 provide high thermal and electrical conductivity in comparison to nickel base alloys , stainless steels and low ALLOY steels.

2 The alloys are Because long-time exposures of ALLOY 200 in the 800 to 1 200 F (427-649 C) range result in precipitation of a carbon phase and loss of ductility, it is not recommended for Service above 600 F (316 C). For applications above 600 F (316 C), the low carbon ALLOY 201 should be For proposed Service temperatures approaching 800 F (427 C), resistance to creep should be considered as a design Food production;//// Fluroine generation;//// Storing and transportation of phenol;//// Manufacture and handling of sodium hydroxide;//// Production of hydrochloric acid and chlorination of hydro-carbons such as benzene, methane and ethane;//// Manufacture of vinyl choloride monomer;//// Heat exchangers;//// Tube sheets;//// Piping;//// Shell plate;//// Tank heads;//// Tanks;//// Storage vessels;//// Mixers.

6 In plate products, this can be achieved by control of the finishing temperature in hot rolling and the elimination of the anneal that follows hot rolling. SHEET and strip can be cold rolled to higher strength. The typical range of enhancement of room temperature properties is shown in the next table.

9 The alloys may also be used in oxidizing environments that cause the formation of a passive oxide Examples of environments in which ALLOY 200 and ALLOY 201 have been used are caustics, high temperature halogens and salts other than oxidizing halides. They are also used in the food processing The nickel content of these alloys renders them virtually immune to chloride stress corrosion cracking. The alloys have been used in fresh and many other process waters with superior ALLOY 200 and ALLOY 201 have been used in caustic solutions such as those encountered in the production of caustic soda when chlorate level is low. Nickel is not susceptible to caustic stress corrosion cracking. When chlorate is about %, as in diaphragm cell technology used in caustic soda production, an iron chromium ALLOY might be Sulfurous atmospheres are corrosive to nickel alloys , especially above 600 F (316 C).

Temperatures in the range of 1 300 F (704 C) to 1 700 F (927 C) may be employed. Car or box anneal cycles which employ long furnace times should use the lower temperatures. Continuous anneal cycles which employ short times should use higher temperatures. If heavy forming is required, anneal time may be increased to provide fully soft material. //// Sulfur, phosphorus, lead, zinc and other low-melting metals are potential contaminants which must be avoided.
