Our Products
Extensively used in the high temperature conditions for welded boilers and pressure vessels, our Low Alloy Steel Plate (ASTM A-SA-387) has huge demand in the market. Our company stands tall among the reliable Suppliers, Importers and Exporters of Low Alloy Steel Plate (ASTM A-SA-387) from Maharashtra. Owing to our reliable logistics network, we are capable of delivering bulk orders of the Low Alloy Steel Plates.
Plates Are Available Under These Specifications In Several Grades Each Having Different Nominal Chromium (Cr) And Molybdenum (Mo) Contents As Follows:
| Grade | Nominal Cr Content (%) | Nominal Mo Content (%) |
| 2 | 0.5 | 0.5 |
| 12 | 1 | 0.5 |
| 11 | 1.25 | 0.5 |
| 22, 22L | 2.25 | 1 |
| 21, 21L | 3 | 1 |
| 5 | 5 | 0.5 |
| 9, 91 | 9 | 1 |
Each grade except Grades 21L, 22L, and 91 is available in two classes of tensile strength described as Class 1 and Class 2. The most regularly specified grades and hence those that are most readily available from stock are Grades 12, 11, 22, 5, and 9 and in most case stock plates will be produced to the tensile requirements of Class 2.
