Polishing Cold rolling EFW ASTM B474 UNS N02201 Alloy 201 pipe
1 Overview:
Commercially pure or low-alloy nickel has characteristics that are useful in several fields, notably chemical processing and electronics. Nickel is highly resistant to various reducing chemicals and is unexcelled in resistance to caustic alkalies. Compared with nickel alloys, commercially pure nickel has high electrical and thermal conductivity. It also has a high Curie temperature and good magnetostrictive properties. Annealed nickel has a low hardness and good ductility and malleability. Those attributes, combined with good weldability, make the metal highly fabricable. Nickel has a relatively low work-hardening rate, but it can be cold worked to moderately high strength levels while maintaining ductility.
Nickel 200 (UNS N02200/W.Nr. 2.4060 & 2.4066) is commercially pure (99.6%) wrought nickel. It has good mechanical properties and excellent resistance to many corrosive environments. Other useful features of the alloy are its magnetic and magnetostrictive properties, high thermal and electrical conductivities, low gas content and low vapor pressure. Chemical composition is shown in Table 1. The corrosion resistance of Nickel 200 makes it particularly useful for maintaining product purity in the handling of foods, synthetic fibers, and caustic alkalies; and also in structural applications where resistance to corrosion is a prime consideration. Other applications include chemical shipping drums, electrical and electronic parts, aerospace and missile components.
Commercially pure wrought Nickel with good mechanical properties over a wide range of temperature and excellent resistance to many corrosives, in particular hydroxides.
Application field:
Many different industries utilize Ni 200, but it is especially useful to those who are looking to maintain the purity of their products. This includes:
Food handling
Manufacturing synthetic fibers
Caustic alkalis
Structural application that demand corrosion resistance
Characteristics
Ni 200 can be hot rolled into practically any shape, and it also responds well cold forming, and machining, as long as established practices are followed. It is also accepts most conventional welding, brazing, and soldering processes.

3.Process for ASTM B474 UNS N02201 Alloy 201 pipe :
Electric Fusion Welding (EFW steel pipe) refers to an electron beam welding, the use of high-speed movement of the electron beam directed impact kinetic energy is converted to heat the workpiece so that the workpiece leaving the melt, the formation of the weld.
It is mainly used for welding dissimilar steel welding sheet or which high power density, metal weldment can rapidly heated to high temperatures, which can melt any refractory metals and alloys. Deep penetration welding fast, heat-affected zone is extremely small, so small performance impact on the joints, the joint almost no distortion. But it has a requirement on a special welding room because welding using X-rays.
ERW pipes means Electric Resistance Welded Pipes.
Electric Resistance Welding (ERW steel pipe): welding member combination is applying pressure through the electrodes, the use of current through the joint area of the contact surface and the adjacent heat generating resistance welding process method, Also known as contact welding. It has excellent toughness and dynamic load strength, welding deformation.
Commonly used spot welding, seam welding and butt three.
