Welcome to BBN High Strength Steels Factory
ASTM A387 Grade 91 EN10025 S690QL properties is a high level steel grade for outstanding heat and anti corrosion and oxidation resistance characteristics, it EN10025 S690QL properties satisifies most applications in fierce working environment with higher requirements.
The company adheres to the people-oriented concept and takes "learning, sharing, gratitude, integrity, respect and responsibility" as the enterprise values. Advanced equipment, scientific standardized management, strict quality assurance system and high-quality team are the core competitiveness of the company. The company will continue to provide customers with EN10025 S690QL properties high-quality, timely and perfect steel products and services under the guidance of the mission of "striving for perfection to meet customer needs".
Punchability refers to the performance of metal without cracks and other defects after stamping deformation. Many steel products are manufactured through a stamping process. In order to ensure the quality of the products and the smooth progress of the process, the EN10025 S690QL properties, steel plates and strips used for stamping must have qualified stamping performance.
Different from EN10025 S690QL properties, the alloy wear-resistant layer of alloy plate is mainly chromium alloy, and other alloy components such as manganese, molybdenum, niobium, nickel are also added. The carbides in the metallurgical structure are distributed in a fibrous shape, and the fiber direction is perpendicular to the surface. Carbide microhardness can reach HV1700-2000 and surface hardness can reach HRC58-62. Alloy carbides have strong stability at high temperatures, maintain high hardness, and also have good anti-oxidation properties. They are fully used within 500°C.
After the order is finished, our after-sales service center will send an email to make a feedback about our steel products' quality. We have phone service every three months to remind our customers of the possible problems and collect advices or suggestions in quality and service. Upon the collection of advices or suggestions, our after-sales service will quickly make technical solutions to wipe out the customer problem.
