NICKEL (200\/201) Pure Nickel Alloys: The Industrial Equivalent of High Purity Performance<\/b><\/b><\/h3>\n

Technical Description<\/b><\/b><\/h3>\n

Nickel (200\/201) are commercially pure nickel-based alloys, both defined as metals with a minimum nickel content of approximately 99.6%. Their basic difference is the carbon content: Nickel 200<\/b><\/span> contains a maximum of 0.15% carbon, while the carbon content of Nickel 201<\/b><\/span> is limited to 0.02%. This difference plays a determining role in high temperature performance and the tendency to graphitisation.<\/p>\n

While Nickel 200 is designed for low temperature applications, Nickel 201 is preferred in chemical process equipment used at high temperature with the aim of minimising carbon precipitation. Both alloys show ferromagnetic properties, their electrical conductivity is high and they are resistant to abrasive environments.<\/p>\n

In terms of typical mechanical properties, Nickel (200\/201) are very similar. At room temperature the tensile strength is approximately 380\u2013450 MPa and the yield strength approximately 100\u2013150 MPa. The ductility<\/a> values are quite high (40-50% elongation at break), which makes forming and cold working operations easier. Thanks to its high electrical conductivity (~22\u201323 MS\/m) and thermal conductivity (~60 W\/m\u00b7K), it is widely used in electrical and thermal systems.<\/p>\n

The corrosion resistance of these alloys is at the highest level especially in alkaline solutions, acetic acid, hydrogen fluoride, anhydrous environments and dry gas atmospheres. Nevertheless, its durability against oxidising acids (for example nitric acid) is limited. For this reason the environmental conditions should be assessed meticulously when making a selection.<\/p>\n

NICKEL (200\/201) <\/b>Relevant Standards<\/b><\/b><\/h3>\n

Nickel (200\/201) has been defined in compliance with a large number of international standards. They appear in both the ASTM and the AMS standards. The principal norms are as follows:<\/p>\n
