Non Ferrous Metals

Alloy 800

This alloy resists hydrogen/hydrogen sulphide corrosion and chloride-ion stress corrosion cracking. It has excellent high temperature strength and immunity to ‘sigma’ phase formation. It is used for pigtails and headers and hydrocarbon ‘cracker’ tubes, for sheathing for heating elements, in nuclear engineering and for other high-temperature processing equipment.

Alloy 904 L

This product resists corrosion and chloride-ion stress corrosion cracking. It has resistant to stress corrosion cracking and pitting and used for chemical plant and pickling plant.

Alloy 625

Enlarge {+}

An alloy with high strength and toughness from cryogenic temperatures to 1100ºC. In addition to good oxidation resistance it resists attack by other media and is virtually immune to chlorideion stress corrosion cracking, it is used in aerospace and is being evaluated for chemical and marine Engineering.

Alloy 600

Cast alloy pig supplied for foundry addition of silicon. For corrosion-resistance castings.

Monel Alloy K 500

An alloy with similar corrosion-resistance to MONEL alloy 400 but amenable to precipitation hardening to give high strength. Used for propeller and pump shafts, bolts, doctor blades and valve spindles.

Monel Alloy 400

Enlarge {+}

A General engineering alloy with good resistance to corrosion by sea water, sulphuric hydrochloric and phosphoric acids, pharmaceutical products, ammonium sulphate, fatty acids etc. it retains its strength and toughness up to about 450ºC and is used for chemical, steam and petroleum plant, marine and pickling equipment.

Nickel 270
