Alloy 718

W-Nr: 2.4668 ASTM: B 637 SAE AMS: 5662, 5663 Alloy 718 was initially developed for the aerospace industry but its excellent strength and corrosion resistance were recognised by the oil industry and it is now widely used in this field also. Alloy 718 is a nickel – chromium alloy which…

Alloy 625

W-Nr: 2.4856 ASTM: B 564, B 446 SAE AMS: 5666 Alloy 625 is a nickel chromium alloy suitable for applications where strength and corrosion resistance are required. The alloy exhibits excellent strength and toughness at temperatures ranging from cryogenic up to 1100ÂșC. The higher strength of this alloy is due…

Alloy 825

W-Nr: 2.4858 ASTM: B 425 Alloy 825 is a nickel-iron-chromium alloy for use in extremely corrosive environments. The nickel content of this alloy makes it resistant to chloride-ion stress-corrosion cracking. Additions of molybdenum and copper give alloy 825 resistance to pitting and to corrosion in reducing acid environments such as…

Alloy 400

W-Nr: 2.4360 ASTM: B 164 A strong weldable, nickel copper alloy resistant to corrosion by seawater. Used in steam generators, feedwater heaters, cladding of offshore installations, pump and propeller shafts, marine fixtures and fasteners, also chemical processing equipment.

Alloy K500

W-Nr: 2.4375 ASTM: B 865 SAE AMS: 4676 Alloy K500 is a nickel-copper alloy with corrosion resistance similar to alloy 400 but with higher strength and hardness which comes from its titanium and aluminium content. Alloy K500 has excellent dimensional stability and low magnetic permeability. It also has excellent cryogenic…
