ALLOY 400, UNS NO4400 Stainless steel tube
Outer Diameter：6-2500mm， (3/8″-100″)
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.

Advantage of Jianglin Seamless Pipe
All about the detail of seamless pipe production.
All of Jianglin raw seamless pipe raw billet are from famous mills like Walsin , Yongxing etc . And
We have advanced NDT equipments for the tests such as Eddy Current test, Ultrasonic test , Hydraulic test and so on . We have ISO 9001 and PED certificate , and the Third Party Inspection Certificates such as TUV , BV , Lloyd’s , SGS , etc , also can be provided according to customers’ requirements .
Each and every pipe will be safely packed into a professional export wooden box. after ordering, our logistics team will check and customize the box to fit into containers.

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 annealing process make the tube inside and outside surface cleaner, meanwhile, this process can guarantee good mechanical property of nickel alloy and super alloy.
For precise stainless seamless tube, each and every tube will be packed into a respective plastic bag, and guarantee the delivery safety.
Quality control is our best advantage
We not only test the raw material chemical composition, but also the intergranular test to guarantee the stable structure.
All of our pipes and tubes will be straightened based on standards. TIR is highly guaranteed.
For precise tube and pipes, we not only stick to standards, but also accept customized tolerance preference.
X Ray test
For welded pipe, we invest greatly on X ray test lab, just want to guarantee all our product meet clients requirement
Surface roughness test
For inner side and outer side surface roughness, we will test it for clients and synchronize all the pictures.
For stainless steel tubes, we have a high requirement on tube line marking, tube package.
with best clients from all over the world
Exhibition all over the world
Package & Loading
With years of experience，we provide different packing and loading method， from basic packing， to wooden box，and we also provide nest packaging.
