The fundamental difference between Nickel 200 and Nickel 201 lies in their carbon content. Nickel 200 is a commercially pure wrought nickel with a maximum carbon content of 0.15%. In contrast, Nickel 201 is the “low-carbon” version, restricted to a maximum of 0.02%.<\/p>\n

    Beyond carbon, both alloys are highly sensitive to sulfur contamination. Exposure to sulfur-bearing compounds at elevated temperatures can cause “sulfur embrittlement.” Sulfur migrates to the grain boundaries, forming a low-melting-point nickel sulfide eutectic that destroys the metal’s ductility.<\/p>\n

    Furthermore, Nickel 200\u2019s sensitivity to carbon precipitation is its “Achilles’ heel” in high-temp scenarios. While Nickel 201 mitigates this, users must still ensure that fabrication processes (like welding or heat treatment) do not introduce exogenous carbon or sulfur. Proper surface cleaning and the use of low-carbon filler metals are essential to maintaining the purity and performance of these alloys.<\/p>\n
