Round bars made of nickel are used in both the field of engineering and industries in general, capable of revolutionising the performance of the product. Being a pure metal, nickel is an excellent ductile material, has a high corrosion resistance, and has stable strength at high temperatures. These properties have contributed to the popularity of nickel round bars to be used in harsh operating conditions like chemical processing, power generation and heat-exposed systems.
In Unifit Fastener, nickel round bars are provided on the basis of the ASTM B160 specifications, which include commercially pure nickel grades, including UNS N02200, UNS N02201 (low-carbon nickel) and UNS N02211 (solution-strengthened nickel). These materials are produced in hot-worked, cold-worked or fully annealed forms to suit various needs in terms of application.
Nickel 200 and Nickel 201 round bars have also been characterised by their good formability and can be easily shaped to other profiles. Flexible shapes are available in common shapes: round, square, hexagonal and rectangular bars, which suit the machining and fabrication requirements. These bars are subjected to rigorous tests in order to maintain a consistent quality, such as tensile strength, yield strength, measuring elongation, and examining hardness.
Besides mechanical testing, a full chemical examination is done to ascertain the material composition and adherence to the industry standard. Unifit Fastener has a bias towards producing nickel round bars of high quality, precision, and reliability which meet international standards and are effective in the industrial sector of the small industries where they are utilised.
Request QuoteNickel Alloy Round Bar is a solid, cylindrically shaped metal rod that is composed of combinations of nickel and other elements (such as chromium, molybdenum, and copper) to form greater strength, toughness, and resistance to heat, corrosion, and oxidation, manifested as superior strength, toughness, and resistance to heat, corrosion, and oxidation compared to the normal metals, thus being essential in aerospace, chemical, marine, and industrial applications where they are unable to resist. These all-purpose bars are cut into different components of high-performance equipment.
