ASTM A320 Standard Specification for Alloy Steel and Stainless Steel Bolts for Low-Temperature Service

EUROLAB laboratory provides testing and compliance services within the scope of ASTM A320 test standard. This specification 2 covers alloy steel bolting materials and bolting components for pressure vessels, valves, flanges and fittings for low temperature service.

The bars will be hot forged and can be further machined by centerless grinding or cold drawing. Austenitic stainless steel can be solution annealed or annealed and strain hardened.

The committee that formulated this specification included various grades of material that are quite commonly used for the present purpose.

Other compositions will be considered for inclusion by the committee from time to time as the need arises. Users should note that the hardenability of some of the grades specified may limit the maximum size at which the required mechanical properties can be achieved.

Values ​​stated in SI units or inch-pound units will be considered standard separately. The values ​​specified in each system may not be exactly equivalent; therefore, each system should be used independently of the other. Combining values ​​from the two systems may result in non-compliance with the standard.
