A615 GR 60, 40 Rebar

Kloeckner Metals is proud to supply high-grade carbon steel rebar in A615 GR 60 and A615 GR 40.


General Info About A-615 GR 60, 40 Rebar

Manufactured from high carbon steel, both A-615 GR 60 and A-615 GR 40 rebar grades provide structural support to concrete and masonry constructions. They reinforce structures with strength and stability. With their reinforcement, they help prevent buildings and other structures from cracking, sagging, collapsing, or experiencing other unwanted and dangerous deformations. They do this by equalizing the distribution of tension and by absorbing stress.

A-615 GR 60 and A-615 GR 40 reinforce concrete slabs columns in the architectural industry. They mainly benefit medium to heavy commercial applications such as walls, roadways, driveways, parking structures, brick buildings, and skyscrapers, among others.

Both A615 GR 60 and A615 GR 40 are routinely stocked from imperial size #3 to #11.

More Details About A615

  • Advantages/Disadvantages

    There are many advantages to using A615 grade 60 steel. It shows the highest benefit when strengthening primary and secondary concrete construction. For example, bridge, road, and other constructions all benefit from this grade of rebar.

    A615 grade 40 steel adds the most benefit when building materials must hold concrete in compression.

    Strength is one of the differentiators for these two rebar grades. The minimum tensile strength for A615 grade 40 steel is 70.05 ksi. It has a minimum yield strength of 40 ksi. This is less than A615 grade 60 which offers a minimum tensile strength at 90 ksi and a minimum yield strength of 60 ksi. Both bar products must have meet ASTM standard specifications for a maximum phosphorus content of .060%.

  • Industries

    A615 grade 60 rebar and A615 grade 40 steel are seen in the architectural industry. They are also used for general construction, special construction, and heavy construction.

  • Applications

    Rebar is used for concrete and building reinforcement, primarily. It can also be used in road construction.

  • Machining

    A615 grade 60 and grade 40 rebar can be easily bent, formed, and cut.

  • Welding

    A615 grade 60 and grade 40 steel are not best for applications that require welding. They are susceptible to cracking. This is mainly due to the higher carbon content of this grade steel, which benefits hardness and tensile strengths at the cost of weldability and ductility.

  • Heat Treatment

    A615 grade 60 and grade 40 steels are heat treatable. However, maintaining a consistent heat treatment can be tricky as rebar is especially susceptible to cracking and embrittlement.

Frequently Asked Questions

  • What is the difference between A615 GR 60 and A615 GR 40?


    The main difference between these two rebar grades is strength. Since rebar is purposed for reinforcement, strength is an important consideration for end use applications. When more strength for reinforcement is needed, A615 GR 60 is the more suitable choice.

  • Can you bend rebar?


    Yes, rebar can be bent. In fact, reinforcing bar is frequently bent to meet the needs for a variety of structures. Bending rebar requires skill, since incorrectly bending rebar could compromise overall structural integrity. Learn more about bending rebar.

  • How is rebar sized?


    ASTM sets the standards for rebar sizes, including A615 GR 60 and 40. ASTM measurements include the weight, area, and diameter. An imperial bar size is available from #3 to #18, wherew the bar diameter increases by 1/8 inch (i.e., #8 rebar = 8/8 inches or 1 inch) in diameter.

    #3 reinforcing bar is a thinner rebar size that can be seen in driveways, outdoor patios and swimming pools, and even some roads and walkways. Strength capacity improves as the imperial size number increases. Kloeckner Metals supplies both of these rebar grades up to size #11. #11 is considered a heavy-duty rebar bar designed for high load structures.
