Organization: ASTM
Publication Date: 1 October 2013
Status: inactive
Page Count: 16
ICS Code (Nuts): 21.060.20
scope:

This specification2 covers a variety of carbon, alloy, and martensitic stainless steel nuts in the size range 1/4 through 4 in. [6.4 through 101.6 mm] nominal. It also covers austenitic stainless steel nuts in the size range 1/4 in. [6.4 mm] nominal and above. These nuts are intended for high-pressure or high-temperature service or both. Grade substitutions without the purchaser's permission are not allowed.

Bars from which the nuts are made shall be hot-wrought. The material may be further processed by centerless grinding or by cold drawing. Austenitic stainless steel may be solution annealed or annealed and strain-hardened.

Supplementary requirements (S 1 through S6) of an optional nature are provided. These shall apply only when specified in the inquiry, contract, and order.

This specification is expressed in both inch-pound units and in SI units. However, unless the order specifies the applicable "M" specification designation (SI units), the material shall be furnished to inch-pound units.

The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Combining values from the two systems may result in noncomformance with the specification.

NOTE-Grade 2M has been replaced with Grade 2HM. During a transition period both grade markings are acceptable.

2 For ASME Boiler and Pressure Vessel Code applications see related Specification SA·194 in Section" of that code.
