ASME SA 387 Gr 91 Plate and Alloy Steel Grade 91 Coil suppliers in India
Grade 91 is a chromium molybdenum alloy steel. As compared to carbon steels, the properties of alloy steels, particularly chromium molybdenum alloy grades such as ASTM A387 Grade 91 Sheet & Plate are suited for pressure purposes. By adding chromium & molybdenum to the steel alloy, the properties of grade 91 go a notch higher. This means the corrosion resistance properties along with resistance to oxidation are also better.

Moreover, the use of deoxidized steel to produce ASTM A387 Grade 91 Sheet also impacts its toughness. Because there are no free air molecules trapped in the alloy, the chances of air bubble formation are drastically reduced. So without any air bubble, the ASTM A387 Grade 91 Alloy Steel Sheet is not porous and there are no weak spots on the material, thus giving rise to a stronger, better product. In order to simplify identification, killed alloy steel SA 387 Gr 91 Plate is marked with the capital letter "K". Grade 91, according to this specification is heat treated. The performance of heat treatment in any form on alloys including the ASTM A387 Grade 91 CL1 plate makes for high quality material, that is able to withstand elevated temperatures. The SA 387 Gr 91 cl2 sheet also exhibits high mechanical strength.
