ASTM Fasteners

Product Details:

ASTM A193 specification covers alloy and stainless steel bolting for pressure vessels, valves, flanges, and fittings for high temperature or high pressure service, or other special purpose applications. Several grades are covered, including ferritic steels and austenitic stainless steels designated B5, B6, B7, B8, B8M, etc. Selection will depend upon design, service conditions, mechanical properties, and high temperature characteristics. This specification is expressed in both inch-pound units and in SI units; however, unless the purchase order or contract specifies the applicable A193M specification designation (SI units), the inch-pound units shall apply

Finishes
When carbon steel helical spring washers are required for galvanizing, this must be indicated on the order or inquiry. ASME standards call for such washers to be coiled to limits 0.020″ in excess of conventional standards. Galvanizing is not recommended for washers under a 1/4″ nominal size.

Helical washers are available in the following finishes:

• Mechanical Zinc
• Electro Zinc
• Mechanical Galvanized
• Hot Dip Galvanized,
• Phosphate Coating
• Black Oxide

Other materials and finishes are available on special request. Mechanical Finish will limit exposure to hydrogen embrittlement unless otherwise specified.

Hardness Testing

 

Figure 3

In preparing a helical spring washer for hardness testing, it should first be twisted to remove the helix and form a near flat surface.

Due to the trapezoidal cross section of the washer, both sides must be filed or ground flat to assure accu­rate readings. This also removes decarburization and plating from the surface. Care must be taken to assure that surface temperature does not exceed 250°F during this operation. (See figure 3.)

An essential requirement of the Rockwell test is that the penetrator be perpendicular to the surface of the test piece and that the test piece not move, in the slightest degree, as the test load is applied. One point of hardness represents a depth of only 0.00008″. A movement of only .001″ could cause an error of over 10 Rockwell numbers.

Penetration should be made in the center of the washer’s flattened surface and readings should not be taken too close together. If the indentation is made too close to the edge of the test washer, the material will yield, giving incorrect low readings. Also, the area surrounding the indent will be cold worked. Subsequent indentations, if made in the cold worked area, will give incorrect readings-usually higher that the virgin material. Also, test penetrations should be made on only one side of the washer.

The thickness of the test sample will determine the correct testing weight to use. Refer to Rockwell test charts to determine proper weight and scale use. To insure the most accurate read­ings, use the maximum weight possible. However, caution should be taken not to use a weight greater that the width and thickness will accommodate
