It provides for anchor bolts in three strength grades, two thread classes, and in the diameters specified in Section 4.
This specification was widely used in the light pole and traffic signal industry long before the ASTM F specification was introduced in and was commonly referred to as A36M Overview ASTM F grade 55 anchor bolts are manufactured from a modified mild steel that has a higher minimum yield strength g ksi than traditional A36 mild steel 36 ksi.
Though relevant for many ge applications and certainly more cost-effective than B7, Grade 55 is still a specialty steel that few manufacturers or distributors supply.

Comments Please describe your product here Such structural supports include building columns, column supports for highway signs, street lighting and traffic signals, steel bearing plates, and similar applications.
Asym 55 is more elastic and available at a lower cost, rendering it more applicable g1554 general construction needs, while B7 is heat treated and contains alloys that make it more suitable for corrosive environments.

The minimum Charpy V-notch energy requirement is an average of 15ft-lbs for three specimens, with no one specimen f554 below 12ft-lbs. When S1 is not specified, the Grade 55 material may or may not be weldable.
The anchor bolts gt furnished in three strength grades, two thread classes, and various sizes, and are intended for anchoring structural supports to concrete foundations such as building columns, column supports for highway signs, street lighting and traffic signals, steel bearing plates, and similar applications. No other units of measurement are included in this standard. In addition to standard round be… https: If S1 is not specified by the purchaser, the Grade 55 material may or may not be weldable.

This increased elasticity means that Grade 55 is most frequently used in the construction industry, as buildings and other infrastructure naturally experience displacement over time. This abstract is a brief summary of the referenced standard.
References to anchor bolts in this standard do not necessarily exclude all-thread rod.
Supplementary requirements shall apply only when specified in the purchase order or contract. The bolts shall adhere to specified elemental chemical compositions as examined by heat and product analysis. Work Item s – proposed revisions of this standard. Permanent grade identification on the end of the anchor bolt that projects from the concrete, in lieu of color coding.
They shall also be tested for their conformance with mechanical properties such as tensile strength, yield strength, elongation, reduction of area, and stress area.
Grade 55 round bar is not commonly available through local warehouses. If weldability is required, supplementary requirement S1 must be specified.

This field should be left blank. Contrary to popular belief, not all grade 55 material is weldable. The anchor bolts shall also meet specified values for nominal size, body diameter, bend section, length, bend angle, and coated length.
Be skeptical of fastener distributors f11554 manufacturers with limited manufacturing capabilities who attempt to substitute round bar or even A grade B7 material for F grade For example, common uses are in chemical and petroleum facilities.
