2520 heat-resistant steel: Why it’s the ideal choice for long-lasting and high-performance W-type radiant tubes

In the manufacturing of W-shaped radiant tubes—a core component of high-temperature industrial furnaces—the choice of material directly determines their lifespan, energy efficiency, and reliability. This article will provide an in-depth analysis of why 2520 heat-resistant steel (310S) has become the industry standard material for handling demanding operating conditions, due to

Are there zinc dross or streaks on the surface of the hot-dip galvanized sheet? The problem might be with the operation of the galvanizing bath

The surface quality of hot-dip galvanized steel sheets is a core indicator of their quality, and zinc dross and streaks are the two most common and significant types of defects. These defects not only damage the product’s appearance but also significantly weaken the corrosion resistance and adhesion of the coating.
