A572 Steel Angle Description

A572 steel angle is a kind of high strength low alloy (HSLA) structural steel, which is widely used in many fields because of its excellent mechanical properties and good weldability. It has high yield strength and tensile strength, and has good impact toughness. Common grades are A572 Gr.42, A572 Gr.50 and A572 Gr.60, which correspond to different yield strength values.

Steel grade: A572.

Specification: ASTM A572.

Technology: hot rolled.

Type: equal & unequal.

Length: as your request.

(1).Equal angle:

Size: 20 × 20 – 200 × 200.

Thickness: 3 to 22 mm.

A572 Steel Angle Properties

1.Chemical Composition

Item Element Content Effect on steel properties
A572 Steel Angle Carbon <0.23% Carbon is the main hardening element in steel, but excessive carbon content will reduce the weldability and toughness of steel.
Manganese ≈1.35% Manganese can significantly improve the strength, hardness and hardenability of steel, while improving the corrosion resistance of steel.
Silicon ≤0.40% Silicon helps to improve the strength and hardness of steel, but also helps to improve the oxidation resistance and corrosion resistance of steel.
Phosphorus <0.040% Phosphorus is a harmful element in steel because it reduces the plasticity and toughness of steel.
Sulphur <0.050% Sulfur causes the “hot brittleness” of steel, which means that steel becomes brittle at high temperatures.

ASTM A572 Steel Angle

Application Field

  1. Construction industry
  • Structural support:

Because of its high strength characteristics, A572 Angle steel is often used for structural support of buildings, such as beams, columns, frames, etc. It can withstand large loads while maintaining the stability and safety of the structure.

  • Bridge construction:

In bridge construction, Angle steel is often used in bridge main beams, piers and support structures.

  • Steel structure plant:

Because of its good workability and weldability, this steel is widely used in the construction of steel structure plants. It can meet the structural strength and stability requirements of the plant, while reducing the construction cost.

  1. Mechanical manufacturing
  • Heavy machinery:

Because of its high strength and wear resistance, it can manufacture heavy machinery equipment, such as excavators, cranes, etc. These devices need to withstand large workloads, and the A572 Angle steel can meet their performance requirements.

  • Auto parts:

It can also manufacture auto parts, such as frames, suspension systems, etc. It can improve the carrying capacity and safety of the vehicle, while reducing the weight of the entire vehicle.

  1. Transportation
  • Railway Facilities:

Manufacturing tracks, Bridges and support structures. It can ensure the stability and safety of railway facilities and improve the efficiency of railway transportation.

  • Shipbuilding:

In shipbuilding, it is often used for hull structure, deck support and so on. It can withstand the corrosion of seawater and various loads during the operation of the ship to ensure the navigation safety of the ship.

  1. Other areas
  • Oil and gas:

Manufacturing drilling platforms, pipeline supports, etc. It can withstand harsh environmental conditions and high pressure and high temperature working environment to ensure the safety and efficiency of oil and gas production.

  • Agricultural equipment:

Manufacture agricultural equipment, such as tractors, harvesters, etc. These devices need to withstand large workloads and harsh working environments, and this steel can meet their performance requirements.
