ASTM F1554

Portland Bolt buys mill runs of round bar and stocks this material for immediate processing. Please describe your threaded product needs with as much detail as possible and we will consult you on what will most benefit your objectives.

This abstract is a brief summary of the referenced standard. 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.

The bolts shall adhere to specified elemental chemical compositions as examined by heat and product analysis.

Your email address will not be published. Washers are detailed in 6. The ASTM F specification was introduced in and covers anchor bolts designed to anchor structural supports to concrete foundations. The purchaser can specify supplemental requirement S1 which requires weldability through chemical composition restrictions and by a carbon equivalency formula.

Welding Contrary to popular belief, not all grade 55 material is weldable. The three grades 36, 55, and designate the minimum yield strength ksi of the anchor bolt. Historical Version s – view previous versions of standard.

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 – Portland Bolt

If weldability is required, supplementary requirement S1 must be specified. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Astn offer a wide selection of materials, finishes, and vr of Figure U-Bolts. 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 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. 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.

In the latest installment of our Threaded series, we discuss materials used to make threaded rod and which work best for certain applications. 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.

F1554 Grade 55

Galvanizing F grade 55 anchor bolts can be provided in either a black or galvanized condition. No other units of measurement are included in this standard. When Grade 36 is specified, a weldable Grade 55 may be furnished at the supplier’s option.

Instead of 555 standard color f15554 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. It is informational only and not an official rg of the standard; the full text of the standard itself must be referred to for its use and application.

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. If S1 is not specified by the purchaser, the Grade 55 material may or may not be weldable.

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. Weldable version of the Grade 55 specification. For additional compatible nuts see the Nut Compatibility Chart.

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.

Supplementary Testing The axtm supplemental requirements apply to F Grade In addition to standard round be… https: The anchor bolts shall also meet specified values for astmm size, body diameter, bend section, length, bend angle, and coated length. Comments Please describe your product here Stamping 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.

Permanent grade identification on the end of the anchor bolt that projects from the concrete, in lieu of color coding.

Supplementary requirements shall apply only when specified in the purchase order or contract. They are both heat treated parts with near identical mechanical and chemical requirements. 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 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.
