ASTM F – Portland Bolt

They shall also be tested for their conformance with mechanical properties such as tensile strength, yield strength, elongation, reduction of area, and stress area. ASTM F grade 55 anchor bolts are manufactured from a modified mild steel that has a higher minimum yield strength atsm ksi than traditional A36 mild steel 36 ksi.

Work Item s – proposed revisions of this standard.

In the latest installment of our Threaded series, we discuss materials used to make threaded rod and which work best for certain applications. Though relevant for many construction applications and certainly more cost-effective than B7, Grade 55 is still a specialty steel that few manufacturers or distributors supply.

Such structural supports include building columns, column supports for highway signs, street lighting and traffic signals, steel bearing plates, and similar applications. Be skeptical of fastener distributors and manufacturers with limited manufacturing capabilities who attempt to substitute round bar or even A grade B7 material for F grade Overview ASTM F grade 55 anchor bolts are manufactured from a modified mild steel that has a higher minimum yield strength 55 ksi than traditional A36 mild steel 36 ksi.

If S1 is not specified by the purchaser, the Grade 55 material may or may not be weldable. Portland Bolt buys mill runs of round bar and stocks this material for immediate processing. Grade 55 is more elastic and available at a lower cost, rendering it more applicable for general construction needs, while B7 is heat treated and contains alloys that make it more suitable for corrosive environments.

Instead of the standard color coding of yellow spray paint to indicate Grade 55, supplemental requirement S3 can be specified by the purchaser to have a permanent grade identification on the end of the anchor bolt that projects from the concrete. 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 References to anchor bolts in this standard do not necessarily exclude all-thread rod.

This field should be left blank. If weldability is required, supplementary requirement S1 must be specified. Materials In the latest installment of our Threaded series, ….

The three grades 36, 55, and designate the minimum yield strength ksi of the anchor bolt. If the application allows for a straight bolt, then B7 can be considered as a substitute for F Grade Historical Version s – view previous versions of standard.

Through chemical composition restrictions and by a carbon equivalency formula, S1 provides assurance of weldability.

The bolts shall adhere to specified elemental chemical compositions as examined by heat and product analysis. Link to Active This link will always route to the current Active version of the standard.

For example, common uses are in chemical and petroleum facilities. It is informational only and not an official part of the 555 the full text of the standard itself must be referred to for its use and application.

For additional compatible nuts see the Nut Compatibility Chart. It provides for anchor bolts in three strength grades, two thread classes, and in the diameters specified in Section 4.

ASTM F1554

Material Substitution Be skeptical of fastener distributors and manufacturers with limited manufacturing capabilities who attempt to substitute round bar or even A grade B7 material for F grade A t1554 DH or A grade 2H should be substituted.

Welding Contrary to popular belief, not all grade 55 material is weldable. The purchaser can specify supplemental requirement S1 which requires weldability through chemical composition restrictions and by a carbon equivalency formula.

F anchor bolts can take the form of either headed bolts, straight rods, or bent anchor bolts. Leave a Comment Cancel reply Your email address will not be published.

All of the grade 55 round bar that Portland Bolt stocks will meet the S1 weldability requirements. Galvanizing F grade 55 anchor bolts can be provided in either a black or galvanized condition. On the other hand, B7 is heat treated, increasing strength but rendering the material more brittle.

B7 is an alloy which includes chromium and molybdenum for added strength and corrosion resistance, rendering it suitable for applications that are highly susceptible to corrosion at high temperatures.

When Grade 36 is specified, a weldable Grade 55 may be furnished at the supplier’s option.
