What does ASTM F1554 mean?
F1554 is an ASTM specification for cast in place anchor bolts. It was established to clarify material properties for anchor rods used in concrete. Prior to it’s creation, concrete anchor bolts were most commonly specified using the generic round bar specification A36 or the headed hex bolt specification A307.
What is the difference between F1554 and A36?
ASTM A36 is a material specification for carbon structural steel. ASTM F1554-36 is fastener specification. The two most common fastener specifications for carbon steel threaded rod are ASTM A307A and ASTM F1554-36.
Is ASTM F1554 grade 105 weldable?
Since F1554 Grade 105 is a high strength alloy steel bolt that generates its strength through the heat treating process, welding to this grade of anchor bolt should be avoided. Additionally, welding to Grade 55 anchor bolts that do not meet the weldability requirements of supplement 1 should also be avoided.
Is F1554 the same as B7?
The primary difference between ASTM F1554 Grade 55 and ASTM A193 B7 is that Grade 55 is more ductile than B7, but nevertheless is appropriate in high-strength applications.
Is A307 and F1554 the same?
The A307 grade A specification only has mechanical requirements for tensile strength (60 ksi minimum) and elongation (18% minimum). F1554 grade 36 has different requirements for tensile and elongation, in addition to having requirements for yield strength and reduction of area.
What is F1554 threaded rod?
F1554 Grade 55 Threaded Rod is manufactured from high strength, low alloy, 55 ksi yield strength steel. The F1554 Specification is designed to cover Threaded Rods, Studs, or Anchor Bolts that will be used as structural supports in concrete foundations. F1554 has three grades which are 36, 55, and 105.
What is F1554 55?
F1554 Grade 55 steel bar is a designed strength, low to medium carbon content grade. It has a 55 ksi yield strength which is required by the F1554 specification for anchor bolt and fastener applications.
What is a Grade 105 bolt?
ASTM F1544 Grade 105 is a standard material specification for straight, bent, headed, headless anchor bolts and all-thread anchor rods, made of low yield carbon steel. ASTM F1554 Grade 105 anchors bolts are designated with minimum yield strength value of 105 ksi or 380 MPa.
What grade is B7 equal to?
Grade 5
ASTM A193 B7 is a chrome-moly steel with strength similar to Grade 5 properties and is commonly used in high temperature and pressure applications.
What is the yield strength of A307 bolts?
Strength Requirements by Grade
Specification | Material and Treatment | Mechanical Properties |
---|---|---|
Yield Strength Min (ksi) | ||
A307 Grade C | Low or Medium Carbon Steel | 36 |
F1554 Grade 36 | Low or Medium Carbon Steel | 36 |
F1554 Grade 55 | Low or Medium Carbon Steel | 55 |
What is Grade A307 equivalent to?
You will often hear about A307 and Grade 2 bolts as being equivalent. While they are small differences they each are referred to as “low carbon” fasteners.
What is the tensile strength of threaded rod?
Threaded rod has a PTFE coating (commonly referred to as the Dupont tradename “Teflon”) and are formulated with superior characteristics for maximum fastener life. Technical components include a tensile strength of up to 4,000 psi and an operating pressure up to 100,000 psi.
Is B7 high tensile?
ASTM A193 Grade B7 is a standard specification for high tensile alloy steel bolting material for use in high temperature or high-pressure service and other special purpose applications.
What is the tensile strength of an 307A bolt?
Governing StandardsA307
Covers the mechanical and material requirements for inch series fasteners in diameters from 1/4″ through 4″, made of carbon steel having a minimum tensile strength of 60,000 psi.
Is A307 high strength?
A307 bolts are not considered high strength bolts. Wooden applications will typically use A307 bolts, for instance. Grade B A307 bolts can have a higher strength and are used for different applications. Typically this grade of bolt is used in piping systems, intended for use in cast iron flanged joints.
What is the tensile strength of A307 bolts?
60000 PSI
ASTM A307 is the standard specification for carbon steel bolts, studs, and threaded rods of 60000 PSI tensile strength in sizes from ¼ inch to 4 inches in diameter.
Which Rod has the highest tensile strength?
Tungsten. Tungsten has the highest tensile strength of any pure metal – up to 500,000 psi at room temperature.
How do you calculate tensile strength?
a) the tensile strength, also known as the ultimate tensile strength, the load at failure divided by the original cross sectional area where the ultimate tensile strength (U.T.S.), σ max = P max /A 0 , where P max = maximum load, A 0 = original cross sectional area.
What is the difference between B7 and L7?
It is a heat treated Chromium Molybdenum steel and is considered for applications up to 450⁰ Centigrade (840⁰ Fahrenheit). L7 has the same chemical and physical properties as B7, with additional Charpy V Notch tests taken at -101⁰ Centigrade (-150⁰ Fahrenheit) for low temperature applications.
Which is better B7 or B7M?
ASTM A193 Grade B7M studs are identical in chemistry to Grade B7, as they are quenched and tempered carbon steel to achieve a lower hardness. However, they have a lower tensile strength than B7 studs.
What is the tensile strength of A307 threaded rod?
60,000 psi
Governing StandardsGrade A307A
Is higher tensile strength better?
The ultimate strength is more important because non-uniform plastic deformation starts at necking. Tensile strength resists tension (being pulled apart), whereas compressive strength resists compression (being pushed together).
What is considered a high tensile strength?
Its tensile strength is 130,000 MPa, which is higher than steel (at 400 – 2,700 MPa). As a result, the material may be manufactured as ultra-thin sheets that are extremely strong and durable.

Mild steel | 840 |
Brass | 500 |
Human hair | 200 |
Is yield strength the same as tensile strength?
In short, yield strength is the maximum stress a material can endure beyond which it begins to permanently deform, not able to return to its original dimensions. Whereas, tensile strength is the maximum tensile stress beyond which a material fails and breaks.
How do you calculate yield strength from tensile strength?
Calculating Yield & Tensile Strength
- Yield Strength. Take the minimum yield in psi of the ASTM grade (see our Strength Requirements by Grade Chart for this value), multiplied by the stress area of the specific diameter (see our Thread Pitch Chart).
- Ultimate Tensile Strength.
- Shear Strength.
