Steel City Bolt – ASTM F Specification
Link to Active This link will always route to the current Active version of the standard. The addition of these alloying elements is costly, and typically means that B7 would be an over-engineered option if used in a general construction application. By Dave Singer 0 comment. ASTM F grade 55 anchor bolts are manufactured from a modified mild steel that has a higher minimum yield strength 55 ksi than traditional 555 mild steel 36 ksi. If weldability is required, supplementary requirement S1 must be specified.
They are both heat treated parts with near identical mechanical and chemical requirements. The ASTM F specification was introduced in and covers anchor bolts designed to anchor structural supports to concrete foundations.
Supplementary requirements shall apply only when specified in the purchase order or contract.
F1554 Grade 55
The minimum Charpy V-notch energy requirement is an average of 15ft-lbs for three specimens, with no one specimen falling below 12ft-lbs.
In the latest installment of our Threaded series, we discuss threaded rod finishes and identify which work best for certain applications. When S1 is not specified, the Grade 55 material may or may not be weldable. 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.
The anchor bolts are furnished in three strength atm, 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.
The following supplemental requirements apply to F Grade This specification covers the chemical, mechanical, and dimensional requirements, 55 associated test methods for straight and bent, headed and headless anchor bolts also known as anchor rods made of carbon, carbon boron, alloy, or high-strength low-alloy steel and having specified yield strengths.
This asgm elasticity means that Grade 55 is most frequently used in the construction industry, as buildings and other infrastructure naturally experience displacement over time. 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.

In this series, we will be covering four common topics to help asfm build the foundation you need to better understand the threaded fastener industry. Welding Contrary to popular belief, not all grade 55 material is weldable.
This specification, however, does not cover the requirements astk mechanical expansion anchors, powder-activated nails or studs, and anchor bolts fabricated from deformed bars. It provides for anchor bolts in three strength grades, two thread classes, and in the diameters specified in Section 4.

F anchor bolts can take the form of either headed bolts, straight rods, or bent anchor bolts.
Supplementary Testing The following supplemental requirements apply to F Grade Through chemical composition restrictions and by a carbon equivalency formula, S1 provides assurance of weldability. This specification was widely used in asym light pole and traffic signal industry long before the ASTM F specification was introduced in and was commonly referred to as A36M File upload If you have a drawing or photo of your custom product, please upload here.
