Nickel 200 and 201 are commercially pure wrought nickel grades with nearly identical properties. The key difference is carbon content: 200 has 0.15% max for service below 315°C, while 201 has 0.02% max for elevated-temperature applications above 315°C .
Alloy 400 is a solid-solution nickel-copper alloy with excellent seawater and HF resistance. Alloy K-500 adds Al+Ti for precipitation hardening, achieving double the strength while maintaining corrosion resistance. Choose based on strength requirements.
Nickel Alloy C-276 (UNS N10276 / 2.4819) is a nickel-molybdenum-chromium-tungsten alloy offering exceptional resistance to pitting, crevice corrosion and stress-corrosion cracking. Available in plate, sheet, round bar and tubing with EN 10204 3.1 certification.
ASTM B409 Alloy 800H plate (UNS N08810 / 1.4876) is a nickel-iron-chromium alloy with controlled carbon content for enhanced creep-rupture strength above 600°C. Available in annealed condition with EN 10204 3.1 certification.
Alloy C-276 is the classic nickel-chromium-molybdenum alloy with high Mo and W for reducing acid resistance. Alloy 22 is the upgraded version with higher Cr for superior oxidizing media and localized corrosion resistance. Choose based on your specific media environment.
