S700MC High Yield Steel – Properties and Applications

S700MC is a high-strength, low-alloy (HSLA) steel that belongs to the microalloyed steel group. It is also known as S700, S700MC steel, or EN 10149-2 S700MC. Here are some key properties and applications of S700MC high yield steel:

High Yield Strength: S700MC has an exceptionally high yield strength, typically around 700 MPa (MegaPascals). This high yield strength enables it to withstand heavy loads and stresses, making it suitable for structural and load-bearing applications where strong and durable materials are required.

Good Formability: Despite its high strength, S700MC exhibits good formability. It can be cold formed and bent without significant risk of cracking or deformation. This allows for the fabrication of complex shapes and structures, providing design flexibility.

Excellent Weldability: S700MC possesses excellent weldability, allowing it to be easily welded using various welding methods such as conventional welding, laser welding, and spot welding. However, proper welding procedures and precautions should be followed to preserve the steel's mechanical properties.

Low Carbon Equivalent: S700MC has a low carbon equivalent, which contributes to its good weldability and formability. The low carbon content also improves the steels' resistance to brittle fracture and enhances its toughness.

Applications: S700MC high yield steel finds application in various industries such as automotive, construction, lifting equipment, and heavy machinery. It is commonly used in components and structures subjected to high dynamic loads, including cranes, truck frames, chassis, trailers, and agricultural equipment. Its high strength-to-weight ratio makes it an attractive choice for weight-sensitive applications.

It is important to note that specific mechanical properties and composition may vary depending on the manufacturer and product specifications. Therefore, it is advisable to consult the relevant standards or technical documentation when working with S700MC steel.
