ASTM F1554 Grade 55 vs ASTM A193 B7
If S1 f5154 not specified by the purchaser, the Grade 55 material may or may not be weldable. Welding Contrary to popular belief, not all grade 55 material is weldable. D1554 of F bolts with manufacturer’s identification is a supplemental requirement S2 Color coding is required unless the grade is stamped in accordance with supplemental requirement S3.
The anchor bolts shall also meet specified values for nominal size, body diameter, bend section, length, bend angle, and coated length.
When Grade 36 is specified, a weldable Grade 55 may be furnished at gf supplier’s option. The specification also covers all-thread rod for use in anchoring to concrete. Supplementary Testing The following supplemental requirements apply to F Grade In the latest installment of our Threaded series, we discuss materials used to make threaded rod and which work best for certain applications. The three grades 36, 55, and designate the minimum yield strength ksi of the anchor 55.
The ASTM F specification was introduced in and covers anchor bolts designed to anchor structural supports to concrete foundations. It provides for anchor bolts in three strength grades, two thread classes, and in the diameters specified in Section 4.
Steel City Bolt – ASTM F Specification
When S1 is not specified, the Grade 55 material may or may not be weldable. 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 covers the chemical, mechanical, and dimensional requirements, and 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.
Referenced Documents purchase separately The documents listed below are referenced within the subject f5154 but are not provided as part of the standard. The minimum Charpy V-notch energy requirement is an average of 15ft-lbs for three specimens, with no one specimen falling below 12ft-lbs. 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 Input Your Industry required.
No other units of measurement are included in this standard. Applications for F anchor bolts include columns in structural steel framed buildings, traffic signal and street lighting poles, and overhead highway sign structures to name just a few.

File upload If you have a drawing or photo of your custom product, please upload here. Contrary to popular belief, not all grade 55 material is weldable. F anchor bolts can take the form of either headed bolts, straight rods, or bent anchor bolts. All of the grade 55 round bar that Portland Bolt stocks will meet the S1 weldability requirements. On the other hand, B7 is heat treated, increasing strength but rendering the material more brittle. This specification, however, does not cover the requirements for mechanical expansion anchors, powder-activated nails or studs, and anchor bolts fabricated from deformed bars.
Permanent grade identification on the end of the anchor bolt that projects from the concrete, in lieu of color coding.
Your email address will not be published. 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.
Please describe your threaded product needs with as much detail as possible and we will consult you on what will most benefit your objectives. They are both heat treated parts with near identical mechanical and chemical requirements. The minimum Charpy V-notch energy requirement is an average of 15ft-lbs for three specimens, atsm no one specimen falling below 12ft-lbs.
F Grades F Grade 36 Low carbon, 36 ksi yield steel anchor bolts F Grade 55 High strength, low alloy, 55 ksi yield steel anchor bolts F Grade Alloy, heat treated, high strength ksi yield steel anchor bolts. It is informational only and not an official part of the standard; ge full text of the standard itself must be referred to for its use and application.
Link to Active This link will always route to the current Active version of the standard. 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.
Permanent manufacturer and grade marking is allowed under the S2 supplementary requirements. A grade DH or A grade 2H should be substituted. By Dave Singer 0 comment.
ASTM F – 18 Standard Specification for Anchor Bolts, Steel, 36, 55, and ksi Yield Strength
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. The anchor bolts are 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.
Washers are detailed in 6. 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. We would like to congratula… https: 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.
Historical Version s – view previous versions of standard. If the application allows for a straight bolt, then B7 can be considered as a substitute for F Grade 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.
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. We offer a wide selection of materials, finishes, and sizes of Figure U-Bolts.

In this series, we will be covering four common topics to help you build the foundation you need to better understand the threaded fastener industry. They shall also be tested for their conformance with mechanical properties such as tensile strength, yield strength, elongation, reduction of area, and stress area.
