SA302 Gr.D Plates Application

1. Industrial boilers, pressure vessels are made from Alloy Steel plates like SA302 Grade D Alloy Steel plates; containing Manganese- Molybdenum, they promote heat dissipation not amounting to deformation in their hard surfaces.

2. ASME SA A302 D Alloy Steel plates are instrumental in building rust free ship hulls and submarines; they are made from fully killed steel, devoid of oxidation, with chromium adding a dash of corrosion proofing from constant contact with sea waters.

3.  Ducting and pipe works, Rail and metal fabricators, automotive and aerospace fabrication, etc. require being hard as nails, with BS 1503-243B Alloy Steel plates providing them with that quality.
