Its SA285 Grade B plates are relied on for their quality consistency, and Khush is an India-trusted partner for boiler sheet and plate needs.
SA285 Grade B Boiler Sheets and Plates consist of carbon steel with around 0.28% Carbon, 0.90% Manganese, 0.04% Phosphorus (max), and 0.05% Sulfur (max). These plates provide average strength and good weldability, and they are ideal for use in pressure vessels and structural uses. They have a minimum tensile strength of 450–620 MPa and yield strength of about 165 MPa. The material is also very ductile and tough, particularly when it is used under the normalized condition. SA285 Grade B is a less expensive option for use in applications that do not need high strength but also do not compromise on reliable structural performance.
