Alloy 400 is a solid solution binary alloy. Because nickel and copper dissolve in each other in any ratio. It is a single phase alloy. It has a face-centered cubic lattice structure with lattice parameters of 3.534 A.

Alloy 400 has excellent binding properties and is a corrosion resistant alloy for a wide range of uses and applications. It has excellent corrosion resistance in hydrofluoric acid, fluorine and other media, and also has good corrosion resistance to hot alkali solution. In addition, the alloy also has good corrosion resistance in neutral solution, water, sea water, air, organic compounds and other environments, usually does not occur stress corrosion cracking, has good cutting performance.

Alloy 400 is resistant to a variety of reducing media. It is also more susceptible to corrosion by oxidizing media than higher copper alloys. This versatility makes alloy 400 suitable for use in a variety of environments;

Alloy 400 is widely used at sea. Alloy 400 products show very low corrosion rate in flowing seawater;Stagnant conditions have been shown to cause cracks and pitting. Alloy 400 is also resistant to stress corrosion cracking and pitting in most fresh and industrial waters;Alloy 400 has excellent corrosion resistance to all concentrations of hydrofluoric acid below the boiling point;

It is probably the most corrosion-resistant of all commonly used engineering alloys. Alloy 400 is also resistant to the reduction of various forms of sulfuric and hydrochloric acid.

STAINLESS STEEL BRIGHT ANNEALED TUBE

Inner roughness Ra 0.4um

Specialized in oiled cold drawing, precision rolling & bright annealed, making the inner and outer pipe surface bright, the roughness can be reach Ra 0.4 um after our polishing process.

Bright annealed

Bright annealing process make the tube inside and outside surface cleaner, meanwhile, this process can guarantee good mechanical property of nickel alloy and super alloy.
