S690Q Hot-Rolled Steel Plate vs S700MC High Yield Structural Steel Plate

S690Q and S700MC are both high-strength steels, but they differ in their specific mechanical properties and production methods.

S690Q is a quenched and tempered (Q&T) steel with a minimum yield strength of 690 MPa and is used for heavy-duty applications like bridges and cranes where weight savings are important.

S700MC is a thermomechanically rolled (MC) steel with a higher minimum yield strength of 700 MPa, known for its excellent formability and weldability, making it suitable for applications requiring complex shapes.

S700mc(1.8974) Vs S690ql(1.8928)

The S700MC Steel is basically a structural steel plate developed especially for applications requiring high yield strength. They are used for several load bearing applications.

The S690ql is a low alloy structural steel which is high in strength and comes with good weldability. They also possess good bending properties. They are a highly versatile product which are mostly used for reducing the weight from various structures.

What is the difference between S700MC and S690ql?

The S700MC Steel is basically a structural steel plate developed especially for applications requiring high yield strength. They are used for several load bearing applications. The S690ql is a low alloy structural steel which is high in strength and comes with good weldability.

What is equivalent to S700MC material?

The equivalent grades of S700MC steel are SEW092 QStE 690TM, NFA36-231 E690D, ASTM A514, BS1449 75F70.

What is the equivalent of S690ql?

S690ql is a structural high-strength grade. The ASTM En 10025 6 S690ql Equivalent Astm is the Q345 grade. The grade exhibits outstanding cold stamping and low-temperature properties

What is S700MC grade steel?

Thanks to its fine-grained microstructure and high degree of purity, grade S700MC is well suited for cold bending, folding and cold flanging without cracking. The name of grade S700MC refers to its upper yield strength. This is 700 MPa.

What is the difference between S690Q and S690QL?

S690Q: Minimum impact toughness tested at -20°C (30J average). → Typical Use: Cranes in temperate climates, quarry equipment. S690QL: Certified for -40°C and below (≥40J impact toughness). → Critical Use: Arctic pipelines, offshore platforms, mining vehicles in Siberia.

What is the ASTM equivalent of S700mc steel?

ASTM A514 grade

Equivalent Astm of S700mc Steel

The versatile high yield strength S700mc Steel Equivalent Astm grade is the ASTM A514 grade.

What is the heat treatment of S700mc?

The heat treatment processes of S700MC significantly influence its microstructure and mechanical properties. Normalizing refines the grain structure, while quenching increases hardness. Tempering is essential to reduce brittleness and enhance toughness, making it suitable for dynamic loading applications.
