DIN W. Nr. 2.4061, 2.4068
Nickel 201 is the low-carbon version of Nickel 200. Because of its low carbon content, Nickel 201 is not subject to embrittlement by intergranularly precipitated carbon or graphite when exposed to temperatures of 315 to 760℃ for prolonged time if carbonaceous materials are not in contact with it. Therefore, it is a substitute for Nickel 200 in Applications above 315℃.
However, it does suffer from intergranular embrittlement by sulfur compounds at temperatures above 315℃. Sodium peroxide can be used to change them to sulfates to counteract their effect.
1. Food processing equipment, salt refining equipment.
2. Mining and marine mining.
3. Equipment required for the manufacture of industrial sodium hydroxide at high temperatures above 300 ° C.
4. Production of organic or inorganic chlorides and fluorides: resistance to chlorine and fluorine gases.
6. Heat treatment furnace in the curved bottles and parts, especially in the carbonation and nitriding atmosphere.
7. Catalytic Regenerators in petrochemical production It is recommended to use alloy 600 for applications with temperatures above 700 ° C for longer service life.
8. Nickel201 is a purely commercial nickel with very low carbon content and has been approved for use in high temperature environments up to 1230 ° C
