What are S690QL plates?
S690QL Plates are high-strength structural steel plates that offer excellent strength, toughness, and weldability. They are primarily used in heavy machinery, construction equipment, mining, and offshore industries.
What is the chemical composition of S690QL plates?
The chemical composition of S690QL plates typically includes elements such as carbon, manganese, silicon, phosphorus, sulfur, chromium, molybdenum, boron, and nickel. The specific composition may vary slightly depending on the manufacturer and standard.
What is the yield strength of S690QL plates?
S690QL plates have a minimum yield strength of 690 MPa (megapascals) or 100 ksi (kilo-pounds per square inch). This high yield strength makes them suitable for applications that require exceptional load-bearing capacity.
What are the benefits of using S690QL plates?
Some key benefits of using S690QL plates include:
What are the typical applications of S690QL plates?
S690QL plates are commonly used in various industries, including:
What is the hardness range of S690QL plates?
S690QL plates generally have a hardness range of 270-340 HB (Brinell hardness). This hardness level provides good resistance to wear and abrasion, making them suitable for applications exposed to harsh operating conditions
