Based in Hyderabad, India, Daksh Sheets and Plates is committed to producing and delivering premium metal sheets and plates that satisfy the various demands of our industrial customers. The SA285 Grade B Boiler Sheet and Plate, which is intended especially for pressure vessel and boiler applications, is one of our best products. SA285 Grade B, which is well-known for its exceptional weldability, moderate strength, and resistance to impact, is the perfect material for fabricating equipment that will be subjected to moderate temperatures and pressures. We offer reliable materials for crucial applications with a strong dedication to quality, accuracy, and performance.
Carbon steel plate SA285 Grade B is designed to be used in boilers and welded pressure vessels. Carbon (0.09–0.15%), manganese (0.30–0.60%), silicon (0.10–0.40%), and phosphorus and sulfur (each ≤0.035%) make up its usual chemical composition. With elongation values of 20% in 200 mm and 23% in 50 mm, this steel grade offers a minimum yield strength of 205 MPa (30,000 psi) and a tensile strength of 380–520 MPa (55,000–75,000 psi). It offers moderate strength, good formability, and excellent weldability, making it suitable for moderate-service conditions.

SA285 Grade B Boiler Sheet and Plate offer several key advantages, making them ideal for pressure vessels and boiler applications. They provide excellent weldability, ensuring strong and reliable joints. The steel’s ability to withstand low to moderate-pressure environments ensures safe operation in boilers and heat exchangers. They have good formability, allowing for easy fabrication into complex shapes. The material’s balance of strength and toughness ensures durability in service, while its cost-effectiveness makes it a popular choice for industrial applications requiring a balance of performance and affordability.
Boiler sheets and plates of SA285 Grade B are frequently used in the construction of boilers, pressure vessels, and associated parts for applications requiring moderate temperatures and pressures. Power generation, chemical processing, and petroleum refining are important industries that depend on this material. It works particularly well for building storage vessels, heat exchangers, tanks, and steam piping—applications where dependability and simplicity of fabrication are essential. Due to its excellent formability, impact resistance, and weldability, the steel offers long-lasting structural integrity, making it a reliable and affordable option for industrial projects requiring moderate performance and safety.
