Nickel 200 and Nickel 201 bars are pure nickel alloys that provide excellent corrosion resistance, good mechanical strength, and outstanding electrical and thermal conductivity. Nickel 200 is a commercially pure wrought nickel with a maximum carbon content of 0.15%, while Nickel 201 is a low-carbon modification with a maximum carbon content of 0.02%. When purchased directly from a factory, these bars are supplied at competitive prices and with guaranteed quality standards such as ASTM B160 and ASME SB160. They are widely used in chemical processing, food handling, electronics, and marine applications.
Chemical Composition of Nickel 200 and Nickel 201 Bars
The primary element in both Nickel 200 and Nickel 201 is nickel, with only minor differences in carbon content. This slight variation improves high-temperature resistance in Nickel 201.
