Nickel 201 Round Bar





While the Alloy 201 hollow Bar is similar to nickel 200 in terms of its chemistry, it should be stressed upon that the Nickel 201 Square Bar almost exclusively caters to the requirements of welding amongst commercially pure wrought alloys.

The low content of carbon in the 201 Forged Bars is what facilitates amazing welding properties of this alloy. Moreover, a low percentage of carbon used to alloy Nickel 201 Round Bar is also what distinguishes both these nickel grades. While both nickel grade 200 and ni 201 hot rolled round bars offer ease in weldability using similar methods to that of austenitic stainless steel grades; the ASME SB160 201 alloy Flat Bars has an exception here.


This being said, it is very important to note that many manufacturers do not encourage the use of an oxyacetylene process to weld the WERKSTOFF NR. 2.4068 Bright Bars. This is because using an oxyacetylene process could be perilous to the ASTM B160 UNS N02201 hex bars of carbon pickup by the alloy. Machining can be carried out on the Alloy 201 Cold Drawn Round Bars with the use of either High-speed steel or cast-alloy tools. Moreover, unlike nickel 200, Alloy 201 Rod is well suited for use over temperatures of 600ºF.

Which manufacturing process gives more toughness to Nickel 201 round bar?

The toughness of a material is the amount of energy a material can absorb before starting to rupture. This is essentially expressed by the tensile strength. The tensile strength of nickel 201 is on average 403MPa in annealed conditions. The cold drawing and annealing process gives the material maximum toughness. The cold drawn and annealed nickel wires can have tensile strengths up to 580MPa. The spring tempered wires have the maximum range of tensile strength at 860-1000MPa. So the spring tempering is the process that gives the nickel 201 the most toughness.
