ASME SA 387 GRADE 11 Class 2
Our alloy steel SA 387 GR. 5 CL. 1/2 plates are expertly crafted for deployment in steel pressure vessels operating at high temperatures and challenging environments. The core composition of this alloy steel incorporates molybdenum, imparting remarkable tensile strength and impressive resistance to corrosion. These plates adhere strictly to the guidelines of ASME SA387, an industry-standard specification governing the production of welded molybdenum steel plates. Their prominence is especially notable in applications requiring performance in elevated temperature conditions.
