Alloy Steel Plates

Alloy steel plates are enhanced with alloying elements such as, chromium, nickel, molybdenum and manganese for better performance than regular carbon steel. These elements make it stronger, harder, more resistant to corrosion and more stable at high temperatures. Dhanlaxmi Steel is a reliable alloy steel plates supplier and stockist. We offer high-quality materials made for industries that need accuracy and dependability. We make sure that every product meets international standards for use in power generation, oil and gas, and engineering by guaranteeing on time delivery and high quality.

Each chromoly steel plate grade we offer is designed for demanding high-temperature and high-pressure applications. The 16Mo3 (EN 10028–2) plate work well up to 500°C making it perfect for heat exchangers and boilers. ASTM A387 Grade 11 and Grade 12 are perfect in pressure vessels and pipelines in the oil, gas and petrochemical industries as they are strong and resistant to corrosion. ASME SA 387 Grade 22 is resistant to creep even at 600°C. We also supply SA387 Grade 9 and Grade 5 plates for environments that need better resistance to oxidation and corrosion.
