S700MC High Yield Steel – Properties and Applications

S700MC: The Star of High-Strength Steel

• Powerhouse Properties: With a yield strength starting at 700 MPa, S700MC is a lightweight champion, keeping structures robust without the bulk.
• Resilient and Ready: This steel shines in the cold and under impact, a must for tough environments.
• Shape-Shifter: High strength doesn't mean rigid—S700MC bends, welds, and machines into a variety of shapes with ease.
• Welding Friendly: It maintains its power when welded, as long as you follow the right procedures.

Where S700MC Shines

• Building Blocks: From crane booms to heavy machinery, S700MC builds the backbone of the industry.
• On the Move: In transport, it's the framework for trucks and trailers that demand durability.
• Dirt and Digging: Earthmoving equipment, like excavators and bulldozers, rely on its strength under pressure.
• Ocean and Sky: It's at home in offshore rigs and reaching for the skies in high-rise construction.
• Storage Solutions: S700MC is the key to strong, tough storage tanks and pressure vessels.
• Heavy Lifting: In mining, agriculture, and more, it's the muscle behind the machinery.

S700MC vs. S690QL: The Steel Showdown

• Standards and Specs: S700MC follows the EN 10149-2 standard for cold-formed components, while S690QL adheres to the EN 10025-6 standard for structural steel plates.
• Chemical Clues: S700MC keeps carbon levels below 0.12% and manganese between 1.40% and 2.10%. S690QL ups the carbon to 0.20% and adds chromium, boron, and molybdenum to the mix.
• Strength Showdown: S700MC starts with a 700 MPa yield strength, perfect for bearing big loads. S690QL, with 690 MPa, is a tough and weldable option for dynamic loads.
• Real-World Roles: S700MC is your go-to for formability in cranes and bridges. S690QL is a strong, tough choice for construction, mining, and energy applications.
• Welding Wisdom: S700MC welds easily, but S690QL may require preheating and specific welding procedures to maintain its high strength.

The Bottom Line

• S700MC: The high-yield steel for lighter, stronger structures that can take a hit.
• S690QL: The high-strength steel for applications that need toughness and can handle a bit of Welding preheating.
