Product Description

SA387 Gr.11 Gr.22 Class 1 Alloy Steel Plate 

ASME SA387 Grade 11 Class 2 is Chrome-Moly steel plate used for welding boilers and pressure vessels designed for high temperature service, nominal chrome content at 1.00% to 1.50%, and Moly 0.45% to 0.65% for SA387 GRADE 11 material. There are two classes available according to tensile strength levels: Class 1 and Class 2.
In the lower end of the temperature range SA 387 Gr 11 (1150 °F min tempering temperature) , and SA 387 Gr 22  (1250 °F min tempering temperature) are used.  These grades can be specified in either class 1 or 2 and can also be provided in the Normalized & Tempered or Quenched and Tempered. For more severe environments we can perform API 934 Testing to supplement this grade.
Provided in Normalized and Tempered or Quenched and Tempered
Supplemental testing available to simulate application and environment conditions
Elevated temper to accommodate API 934
