At DLX Alloy, we produce high-performance Nickel 201 sheets (UNS N02201) engineered for harsh chemical environments where stability, purity, and long service life are critical. Designed under ASTM B162 standards, our low-carbon pure nickel sheets are especially suitable for caustic evaporators and chemical processing equipment where conventional materials often fail over time.
Product Overview
Nickel 201 is a low-carbon version of Nickel 200 , specifically developed to prevent embrittlement in high-temperature environments. With carbon content typically below 0.02%, this material avoids the formation of graphite at elevated temperatures, making it more reliable in long-term thermal exposure.
At DLX Alloy, our Nickel 201 sheets are supplied in bright annealed or pickled conditions, offering excellent surface quality and consistent mechanical properties. These sheets are easy to fabricate, weld, and form, making them ideal for complex chemical equipment manufacturing.
