ASTM B709 Alloy 28 Sheets & Plates

ASTM B709 Alloy 28 UNS N0828 Plates and Sheets are highly popular metallic products in the manufacturing industry. Amongst their many features, they offer unmatched corrosion resistance properties. Three distinct types of Alloy 28 UNS N0828 Plates are categorized based on their thickness and dimensions. The first type is the hot-rolled plate produced through hot rolling at high temperatures. This type is designed for moderate temperatures and high-pressure applications. The second type is the cold-rolled plate produced through cold rolling. This type has better surface finishing, high precision, and strength. And they have precision rolled plates manufactured using rolling mills and customized precision cutting. This type provides excellent flatness and tight tolerance.
