Steel is undoubtedly one of the most important materials the modern world uses. It comes in many different grades designed to meet specific needs and applications. In this article, we will look at one of those grades – E350 grade steel.
E350 grade steel is a widely used construction material known for its high strength and excellent durability. It is commonly used to construct bridges, buildings, and other large steel structures. This article will provide a comprehensive guide to E350 grade steel, including its chemical composition, properties, and applications.
What is E350 Grade Steel?
E350 grade steel is a medium carbon structural steel type with excellent weldability and formability characteristics. It can be used in applications requiring higher strength than mild steel, such as construction, automotive components and machine parts. It also has a tensile strength of up to 550MPa and yield strength of 350MPa or more, depending on the heat treatment applied. Additionally, it provides good resistance to corrosion and wear due to its good combination of hardness and toughness.
Chemical Composition
E350 grade steel is a low-carbon steel that contains carbon, silicon, and manganese as the primary alloying elements. Carbon imparts strength and hardness to the steel, while silicon and manganese help improve its toughness and workability. Carbon: 0.20%, Silicon: 0.50%, Manganese: 1.50%, Phosphorus: 0.050%, Sulphur: 0.050%
Properties
Properties of E350 Grade Steel
- E350 Grade Steel is a structural steel that belongs to the category of low alloy steels.
- It comprises manganese, phosphorus, sulfur, and silicon as the main alloying elements.
- The tensile strength of E350 Grade Steel ranges from 540 MPa to 770 MPa, and its yield strength ranges from 355 MPas to 430MPa.
- It also has good weldability and high resistance to corrosion, making it ideal for several industrial applications such as shipbuilding, construction of bridges, mechanical manufacturing etc.
- Due to its low cost and superior properties compared to other materials such as iron or aluminum alloys, E350 Grade Steel has become one of the most popular materials for engineers in recent years.
Applications
E350 grade steel is widely used in the construction of buildings, bridges, and other steel structures due to its excellent strength and durability. It is also used in manufacturing automotive parts, pipes, and tubes, as well as in producing agricultural machinery and equipment.
