(Specification)Standard Specification for Nickel Rod and Bar
Standard Specification for Nickel Rod and Bar
ABSTRACT
This specification covers nickel (UNS N02200), low carbon nickel (UNS N02201), and solution strengthened nickel (UNS N02211) in the form of hot-worked, cold-worked, or annealed rods and bars of round, square, hexagonal, or rectangular solid section. The material shall conform to the chemical composition limits specified for nickel, copper, iron, manganese, carbon, silicon, and sulfur. Mechanical requirements including tensile strength, yield strength, and elongation are given for specific conditions and diameter or distance between parallel surfaces. Chemical analysis, tension test, and hardness test shall be performed.
SCOPE
1.1 This specification covers nickel (UNS N02200)*, low carbon nickel (UNS N02201)*, and solution strengthened nickel (UNS N02211) in the form of hot-worked and cold-worked rod and bar in the conditions shown in Table 1.
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to become familiar with all hazards including those identified in the appropriate Material Safety Data Sheet (MSDS) for this product/material as provided by the manufacturer, to establish appropriate safety and health practices, and determine the applicability of regulatory limitations prior to use.

A
Dimensions apply to diameter of rounds, to distance between parallel surfaces
of hexagons and squares, and separately to width and thickness of rectangles.
7.3 Corners—Cold-worked bars will have practically exact angles and sharp corners.
7.4 Machining Allowances for Hot-Worked Materials—When the surfaces of hot-worked products are to be machined, the
allowances prescribed in Table 5 are recommended for normal machining operations.
7.5 Length—The permissible variations in length of cold-worked and hot-worked rod and bar shall be as prescribed in Table
6.
7.5.1 Rods and bars ordered to random or nominal lengths will be furnished with either cropped or saw-cut ends; material
ordered to cut lengths will be furnished with square saw-cut or machined ends.
7.6 Straightness:
7.6.1 The permissible variations in straightness of cold-worked rod and bar as determined by the departure from straightness
shall be as prescribed in Table 7.
7.6.2 The permissible variations in straightness of precision straightened cold-worked rod as determined by the departure from
straightness shall be as prescribed in Table 8.
7.6.2.1 In determining straightness in the standard 42-in. (1.07-m) distance between supports or, when specified, in determining
straightness in lengths not in excess of those shown in Table 8, the rod shall be placed on a precision table equipped with
ballbearing rollers and a micrometer or dial indicator. The rod shall then be rotated slowly against the indicator, and the deviation
from straightness in any portion of the rod between the supports shall not exceed the permissible variations prescribed in Table
8. The deviation from straightness (throw in one revolution) is defined as the difference between the maximum and minimum
readings of the dial indicator in one complete revolution of the rod.

The allowances for hot-worked material in Table 5 are recommended for rods machined in lengths of 3 ft (0.91 m) or less and for bars machined in lengths of2ft(0.61
m) or less. Hot-worked material to be machined longer lengths should be specified showing the finished cross-sectional dimension and the length in which the material
will be machined in order that the manufacturer may supply material with sufficient oversize, including allowance for out-of-straightness.
