Q1: What is Ni201 (UNS N02201) nickel alloy?
A1: Ni201 is a commercially pure wrought nickel alloy (≥99.5% Ni) with low carbon content, offering excellent corrosion resistance, high thermal and electrical conductivity, and good mechanical properties.
Q2: What are the typical applications of Ni201 bars?
A2: Ni201 bars are widely used in chemical processing, food production, synthetic fiber manufacturing, alkali handling, electrical and electronic components, and parts requiring resistance to caustic alkalis and neutral/alkaline salt solutions.
Q3: How does Ni201 differ from Ni200?
A3: Both Ni200 and Ni201 are commercially pure nickel alloys. The main difference is that Ni201 has a lower carbon content, which enhances its resistance to graphitization and makes it more suitable for applications involving high temperatures (above 600 °F / 315 °C).
Q4: What standards apply to Ni201 nickel bars?
A4: Ni201 bars are manufactured to international standards such as ASTM B160, ASME SB-160, and equivalent DIN standards. These standards cover chemical composition, mechanical properties, and dimensional tolerances.
Q5: What factors influence the price of Ni201 commercial pure nickel bars?
A5: Pricing is determined by factors such as bar diameter, length, tolerance requirements, order quantity, processing (hot-rolled or cold-drawn), and fluctuations in global nickel raw material prices.
