Nickel Steel Welded pipe and Tube
Nickel is used in making alloys of both ferrous and nonferrous metals. Chemical and food processing equipment, electrical resistance heating elements, ornamental trim and parts that must withstand elevated temperatures are all produced from nickel containing metal. Alloyed with chromium it is used to make stainless steel. Nickel alloy are either welded by either gas or arc methods and can be machined, forged, cast and easily formed.
Types of Nickel Alloys
- Commercially pure nickel – High purity nickel contains 99.99% Ni. Commercially pure nickel contains 99.5% Ni. Microstructure consists of solid solution phase in annealed condition. It has excellent resistance to most corrosive environment.
- Nickel copper alloys – It forms complete solid solution. It contains 67% of nickel and 33% of copper.
- Nickel-chromium alloys – Chromium forms a solid solution with nickel up to infinity of 30% at room temperature. High corrosion resistance is due to high Cr addition.
- Nickel-base super alloys – It is basically from high temperature heat-resistance alloys, which can retain high strengths at elevated temperatures. There are types of nickel-base super alloys that is nickel base, iron base and cobalt base.
- Nickel-iron super alloys – It is used at lower temperature. It contains 25-45% nickel and 15-65% iron. Higher nickel content increases operating temperature (up to 815 degree Celsius), due to improved stability but more costly.
- Product identifier – It can be identified in different forms like semi-finished products, plates, sheets, bar, rod, wire, tube, fitting and strip.
- Relevant identified uses of mixture – It is used in the chemical, oil and gas, aviation and nuclear industries, in demanding environments including corrosive conditions or in high temperatures including corrosive gases.
- Details of the supplier – Manufacturer and suppliers name should be written.
- Emergency identification
- Classification of mixture – Nickel metal is classified in EC Directive 67/548/EEC as a suspect carcinogen and a skin sensitizer.
- Label elements – Since there products are alloys, labelling is not required.
