Low Alloy Steel Standard Grade Table
Modern low alloy steels are in many respects more advanced than their predecessors and are now used in a wide variety of applications. A variety of grades of low alloy steel are available today, most of which have undergone significant improvements in performance. This article provides information about the major low alloy steel standards and their grades.
ASTM A572:
A572 is a high-strength, low-alloy steel that is found in many structural applications and shares a number of characteristics with other grades of high-strength and low-alloy steels. A572 is often used in bridge building and other heavy construction applications due to its ability to meet specified mechanical properties at relatively low cost.
ASTM A514:
A514 is a low-alloy steel that is ideal for applications that require high strength and excellent weldability. It has superior abrasion resistance and enhanced strength when compared to other low-alloy steels. As A514 is designed for applications that require superior strength, it is often used in the construction of bridges and other heavy equipment.
ASTM A242:
A242 is a high-strength, low-alloy steel that is highly resistant to corrosion and provides excellent strength at elevated temperatures. It is often used in applications such as bridge construction or other applications that require excellent corrosion resistance.
ASTM A588:
A588 is a high-strength, low-alloy steel that has excellent corrosion resistance. It is most often used in applications that require corrosion resistance and is ideal for use in bridge construction, structural steel and other forms of heavy construction.
ASTM A709:
A709 is a low-alloy steel that is able to provide excellent strength, weldability and corrosion resistance. It has a high strength-to-weight ratio, making it ideal for many applications. A709 is often used in bridge construction and other heavy construction applications.
ASTM A913:
A913 is a low-alloy steel that is designed to provide strength and weldability. It has an excellent combination of strength and corrosion resistance, making it ideal for a variety of high-strength applications.
ASTM A606:
A606 is a high-strength, low-alloy steel that is often used in bridge construction and other heavy construction applications due to its good weldability and resistance to corrosion. This grade is ideal for applications that require relatively low cost and excellent corrosion resistance.
ASTM A656:
A656 is a low-alloy steel that provides excellent strength, durability and formability. It has a high strength-to-weight ratio and is ideal for applications that require low cost and good formability.
ASTM A871:
A871 is a low-alloy steel that is designed to provide excellent strength at elevated temperatures. It is often used in applications that require corrosion resistance and enhanced strength.
ASTM A1011:
A1011 is a hot-rolled, low-alloy steel that is ideal for applications that require strength and durability at elevated temperatures. It is often used in applications such as construction of bridges and other heavy construction applications.
ASTM A1018:
A1018 is a low-alloy steel that provides excellent weldability and formability. It is often used in a variety of applications due to its ability to meet specified mechanical properties at relatively low cost.
ASTM A1045:
A1045 is an ultra-high-strength, low-alloy steel that is ideal for use in applications that require excellent weldability and improved toughness. It is often used in critical applications such as crane booms and other heavy construction equipment.
ASTM A1070:
A1070 is a low-alloy steel that is designed to provide excellent strength and formability. It is often used in a variety of applications due to its ability to meet specified mechanical properties at relatively low cost.
ASTM A1095:
A1095 is a low-alloy steel that offers excellent strength and formability. It is often used in applications such as bridge construction, structural steel and other forms of heavy construction due to its good strength and formability.
In conclusion, different grades of low alloy steels are available, each offering unique advantages for specific applications. The above grades provide an overview of some of the most common low alloy steel standards and grades currently in use. Familiarity with these different grades can help ensure that the proper grade is chosen for any given project.
