ASTM Standard A36
ASTM International works with industry leaders worldwide to ensure the safety and reliability of all types of materials. They maintain over 12,000 standards for all varieties of industry, including steel components used in construction applications.
The ASTM A36 designation covers a carbon structural steel alloy. This steel is essential for applications ranging from bridges, oil rigs, and parking garages to boat ramps and simple walkways. A36 steel is used for some of the industry’s toughest applications and conditions, produced in forms that include:
Essential for Structural Applications
A36 steel is a very frequently used mild- or hot-rolled steel. It maintains a somewhat rough surface and can be machined and manipulated using a variety of processes. These include multiple types of welding, as well as grinding, drilling, punching, and riveting.
Its flexibility and strength make A36 steel suitable for a full variety of applications, including fixtures, rings, forming tanks, bearing plates, cams, and gears, among many others.
Strength and Flexibility
With a tensile yield strength of 36,300 psi and an ultimate tensile strength that ranges from 58,000 to 80,000 psi, A36 steel combines strength with flexibility. A36 steel can maintain its strength at temperatures ranging up to 650°F. This metal is excellent for welding and produces high quality welded joints. While A36 is a strong material, it is more easily bent than materials such as C1018 steel, as it has less yield strength.
The following elements generally compose A36 grade steel:
• 98% Iron
• 0.25% – 0.290% Carbon
• 0.20% Copper
• 1.03% Manganese
• 0.280% Silicon
• 0.040% Phosphorous
• 0.050% Sulfur
