Commonly used are the following grades of heat-treated alloy steel for high-pressure or extreme temperature service in diameters of 1/2 in. to 2 in., inclusive. Other grades and other diameters are available on special order.
ASTM A354, Grades BC and BD - heat-treated alloy steels for applications at normal atmospheric temperatures where high strength is required.
ASTM A193, Grade B7 - a heat-treated chromium-molybdenum steel widely used for medium high-temperature service.
ASTM A193, Grade B16 - a heat-treated chromium-molybdenum-vanadium steel for high-pressure, high-temperature service.
ASTM A320, Grade L7 - This grade is intended for low-temperature service down to minus 150ºF and has a minimum Charpy impact value of 15 ft-lb at this temperature. Sizes 2-1/2 in. and under.
ASTM A320, Grade L43 - The same properties offered by Grade L7 in sizes up to 2-1/2 are obtainable up to 4 in. in Grade L43

NOTES:
- In addition to the indicated grade marking, all grades, except A563 grades O, A and B, must be marked for manufacturer identification.
- The markings shown for all grades of A194 nuts are for cold formed and hot forged nuts. When nuts are machined from bar stock the nut must be additionally marked with the letter 'B'.
- Nuts are not required to be marked unless specified by the purchaser. When marked, the identification marking shall be the grade letter O, A or B.
- Properties shown are those of nonplated or noncoated coarse thread hex nuts.
- Properties shown are those of coarse thread heavy hex nuts.
- Properties shown are those of coarse thread heavy hex nuts.
- Properties shown are those of coarse 8-pitch thread heavy hex nuts.
- Hardnesses are Brinell Hardness Numbers.
- The nut manufacturer, at his option, may add other markings to indicate the use of atmospheric corrosion resistant steel.

Notes for Table 10.
-
When only the ISO property class number is shown in Table 10, below, the class is standard in both ISO 898-1 and ASTM documents. Properties specified in each are identical except for minor exceptions. Where differences exist, the ASTM F 568M values are given.
-
To compute the tensile proof load, tensile yield strength, or tensile ultimate strength in kilonewtons (kN) for a bolt, screw, or stud, multiply the stress value (MPa) in Table 10 by the tensile stress area (mm^2) of the product's screw thread as given in Table 9 or Standard Metric Bolt Shank Dimensions, then divide this result by 1000.
-
In general, identification markings are located on the top of the head and preferably are raised.
-
Class 5.8 products are available in lengths 150 mm and less.
-
Caution is advised when considering the use of property class 12.9 products. The capabilities of the fastener manufacturer, as well as the anticipated service environment, should be carefully considered. Some environments may cause stress corrosion cracking of nonplated, as well as electroplated, products.
