(Specification)Standard Specification for Nickel Plate, Sheet, and Strip
Standard Specification for Nickel Plate, Sheet, and Strip
ABSTRACT
This specification covers rolled nickel (UNS N02200) and low-carbon nickel (UNS N02201) plate, sheet, and strip. The material shall conform to the chemical requirements for nickel, copper, iron, manganese, carbon, silicon, and sulfur. The material shall conform to the mechanical property requirements for tensile strength, yield strength, elongation, and Rockwell hardness. For deep drawing and spinning quality sheet and strip, the material shall conform to specified values for grain size and hardness properties. The material shall be uniform in quality and temper, smooth, commercially straight or flat, and free of injurious imperfections. Test methods (chemical analysis, mechanical test, grain size test) shall be performed in accordance to referenced ASTM documents itemized herein.
SCOPE
1.1 This specification covers rolled nickel (UNS N02200) and low-carbon nickel (UNS N02201)* plate, sheet, and strip.
1.2 The values stated in inch-pound units are to be regarded as the standard. The other values given are for information only.
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.

Yield strength requirements do not apply to material under 0.020 in. (0.51 mm) in thickness.
B
For Rockwell or equivalent hardness conversions see Hardness Conversion Tables E 140.
C
Caution should be observed in using the Rockwell test on thin material, as the results may be affected by specimen thickness. For thicknesses under 0.050 in. (1.3
mm), the use of the Rockwell superficial or the Vickers hardness test is suggested.
D
As-rolled plate may be given a stress-relieving heat treatment subsequent to final rolling.
E
As-rolled plate specified “suitable for hot forming” shall be furnished from heats of known good hot-malleability characteristics (see X1.2.2). There are no applicable
tensile or hardness requirements for such material.
F
Sheet and strip 0.010 to 0.049 in. (0.25 to 1.2 mm), inclusive, in thickness shall have an elongation of 30 % minimum. Sheet and strip 0.050 to 0.109 in. (1.3 to 2.7
mm), inclusive, in thickness shall have an elongation of 35 % minimum.
G
Not applicable for thickness under 0.010 in. (0.25 mm).

Sheet requirements in Table 4 apply to strip thicknesses over 0.125 in. (3.2 mm), and for all thicknesses of strip over 12 in. (305 mm) in width.
E
For ductility evaluations for strip under 0.005 in. (0.13 mm) in thickness, the spring-back test, such as that described in Test Method F 155, is often used and the
manufacturer should be consulted.
F
Accurate grain size and hardness determinations are difficult to make on strip under 0.005 in. (0.13 mm) in thickness and are not recommended.

permissible excess in overweight shall not exceed the amounts prescribed in Table 5.

the amounts prescribed in Table 6.
