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 .
Nickel Alloy K-500 (UNS N05500 / 2.4375) is a precipitation-hardenable nickel-copper alloy with the corrosion resistance of Alloy 400 and significantly higher strength and hardness. Available in plate, round bar and wire with EN 10204 3.1 certification .
Alloy 625 is a solid-solution strengthened alloy prized for outstanding corrosion resistance. Alloy 718 is precipitation-hardenable for exceptionally high strength at elevated temperatures. Choose based on corrosion vs strength requirements.
Nickel alloy plate, sheet, coil, pipe, tube, bar, wire and forgings for corrosive, high-temperature and high-strength service. Materials can be specified by UNS grade, product standard, condition, dimensions and required inspection documentation.
Inconel 625 (UNS N06625 / 2.4856) nickel-chromium-molybdenum-niobium alloy supplied as plate, sheet, coil, pipe, tube, bar, wire and fittings to ASTM/ASME standards, with cutting, machining, testing and EN 10204 3.1 certification.
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.
Alloy 625 is a nickel-chromium-molybdenum-niobium alloy with exceptional strength and corrosion resistance to 980°C. Alloy 825 is a nickel-iron-chromium alloy for sulfuric/phosphoric acid service at moderate temperatures. 625 costs ~5-6x CS; 825 ~3-4x CS.
Alloy 600 is a versatile Ni-Cr-Fe alloy valued for broad corrosion resistance and immunity to chloride SCC. Alloy 601 is designed for superior oxidation resistance at elevated temperatures with higher Cr and Al content. Choose based on temperature and environment.
Alloy 800 is the standard Ni-Fe-Cr alloy for service below 600°C. Alloy 800H features controlled carbon and coarse grain for enhanced creep strength above 600°C. Alloy 800HT further tightens Al+Ti control for maximum creep resistance up to 900°C+.
