ASTM A194 GR.8
ASTM A194 pecification
covers a variety of carbon, alloy, and martensitic and austenitic stainless
steel nuts. These nuts are intended for high-pressure or high-temperature
service, or both. Bars from which the nuts are made shall be hot-wrought.
According to ASTM A194 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. Each alloy shall conform to the chemical
composition requirements prescribed. Hardness tests, proof of load tests, and
cone proof load tests shall be made to all nuts to meet the requirements
specified.
ASTM A194 stated in either inch-pound units or SI units are to be regarded
separately as standard. 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 nonconformance with the
specification. Within the text, the SI units are shown in brackets.
ASTM A194 covers size range ? through 4 in. and metric M6 through M100 nominal.
It also covers austenitic stainless steel nuts in the size range ? in. and M6
nominal and above.
Unless otherwise specified, the American National Standard Heavy Hex Series
(ANSI B 18.2.2) shall be used. Nuts up to and including 1 inch nominal size
shall be UNC Series Class2B fit. Nuts over 1 inch nominal size shall be either
UNC Series Class 2B fit or 8 UN Series Class 2B fit. High strength ASTM A194
grade 2H nuts are common in the marketplace
