Selection will depend on design, service conditions, mechanical properties, and low-temperature characteristics. 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. The committee formulating this specification has included several grades of material that have been rather extensively used for the present purpose. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

The material, as represented by the tension specimens, shall conform to the requirements as to tensile properties such as tensile strength, yield strength, elongation, and hardness. Quick Quote View Catalog.

Within the text, the SI units are shown in brackets. The committee formulating this specification has included several grades of material that have been rather extensively used for the present purpose.

ASTM A320 Specification

Being centrally headquartered in Baton Rouge, Louisiana, we are capable of shipping to jobsites all qstm the world. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

Combining values from the two systems may result in nonconformance with the specification. Unless the order specifies the applicable "M" specification designation SI unitsthe material shall be furnished to inch-pound units.

ASTM A - Portland Bolt

Austenitic stainless steel may be solution annealed or annealed and strain-hardened. The material shall meet the prescribed impact energy absorption requirements and the recommended test temperature. Many of our industrial projects that we supply material to include anchor bolts, and also stud bolts of many different ASTM grades.

It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. Class 1A products are solution treated in the finished condition for corrosion resistance; heat treatment is critical for enhancing this physical property and meeting the mechanical property requirements.

The term "bolting material" as used in this specification covers rolled, forged, or strain hardened bars, bolts, screws, studs, and Stud Bolts. ASTM A specification covers alloy steel bolting materials for pressure vessels, valves, flanges, and fittings for low-temperature service. The manufacturer should determine that the material can conform to these requirements before parts are manufactured.

Each alloy shall conform to the prescribed chemical composition requirements. The supplementary requirements shall apply only when specified in the purchase order or contract. Combining values from the two systems may result in nonconformance with the specification.

Several grades are covered, including both ferritic and austenitic steels designated L7, B8, etc. Our niche in exotic high nickel alloy fasteners include materials such as: The material, as represented by the tension specimens, shall conform to the requirements as to tensile properties such as tensile strength, yield strength, elongation, and hardness. Users should note that hardenability of some of the grades mentioned may restrict the maximum size at which the required mechanical properties are obtainable.

The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. When strain hardened austenitic stainless steel is ordered, the purchaser should take special care to ensure that Appendix X1 is thoroughly understood. They are not intended as absolute limits beyond which bolting materials could no longer be certified to the specification.

ASTM A L7M STUD BOLTS

The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Selection will depend on design, service conditions, z320 properties, and low-temperature characteristics. Mechanical tests shall be conducted on the material, namely: About the American Society for Testing and Materials.

Users should note that hardenability of some of the grades mentioned may restrict the maximum size at which the required mechanical properties are obtainable.

ASTM A320 Grade B8M Fasteners

Work Item s - proposed revisions of this standard. Class 2 products are made from solution-treated material that has been strain hardened. The material shall meet the prescribed impact energy absorption requirements and the recommended test temperature. Combining values from the two systems may result in non-conformance with the standard.
