When we talk about S690 steel, most people don’t exactly know what it is. S690 steel is the substructure of many constructions, crane equipment, and offshore drilling platforms. The steel’s high yield strength and toughness make it well-suited for these demanding applications. Delta Heat Services is experienced in preheating steel, including S690 steel. Are you interested in preheating S690 steel? Then, definitely stay on this page.

More about S690 steel

S690 steel is a high-strength, low-alloy structural steel that is part of the group of steels defined by their yield strength, in this case, 690 megapascals (MPa). This type of steel is known for its exceptional strength and is used in applications where high strength and weight reduction are important. Here are some key aspects of S690 steel:

  • High yield strength: The defining characteristic of S690 steel is its high yield strength, which is typically around 690 MPa. It means the steel can withstand significant stress before it begins to deform permanently.
  • Weldability: Despite its high strength, S690 steel is known for its good weldability. This makes it easier to use in the construction of complex structures where welding is a necessary part of the assembly process.
  • Toughness: In addition to its strength, S690 steel also has good toughness, which makes it resistant to fracture, especially in environments where there might be a combination of high stress and dynamic loads.

Based on the above strengths you can deduce that S690 steel is a very strong material which makes it very popular in various sectors. Especially in construction and heavy machinery manufacturing. Its ability to reduce weight while maintaining structural integrity is a key factor in its widespread use.

The preheating process of S690 steel

S690 steel is perfect for welding, but is it also easy to preheat? The answer is: yes. When you’re about to preheat the S690 you need to be careful about the process. That’s also important when you’re about to weld it. Both processes require specific knowledge and skills to maintain the high quality and performance of the steel. It is always advisable to work with professionals who have experience with this type of advanced steel material.

It’s because the excessive temperatures can alter the microstructure of the steel, which can lead to a reduction in mechanical properties such as toughness, strength, and ductility. Therefore, it is important to carefully control the heating processes and follow the recommended temperature limits.
