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 Thickness’ from 3/16” – 10” Supplemental testing available to simulate application and environment conditions Elevated temper to accommodate API 934 In the tables use SA 387 Gr 11 and SA 387 Gr 22 Chemical Requirements *Elements represented in percentage Element Composition % SA 387 Grade 11 SA 387 Grade 22 Carbon, max: Heat analysis 0.05-0.17 0.05-0.15A Product analysis 0.04-0.17 0.04-0.15A Manganese, max: Heat analysis 0.40-0.65 0.30-0.60 Product analysis 0.35-0.73 0.25-0.66 Phosphorus, max: Heat analysis 0.025 0.025 Product analysis 0.025 0.025 Sulfur, max: Heat analysis 0.025 0.025 Product analysis 0.025 0.025 Silicon: Heat analysis 0.50-0.80 0.50 max Product analysis 0.44-0.86 0.50 max Chromium: Heat analysis 1.00-1.50 2.00-2.50 Product analysis 0.94-1.56 1.88-2.62 Molybdenum: Heat analysis 0.45-0.65 0.90-1.10 Product analysis 0.40-0.70 0.85-1.15 Tensile Requirements For Class 1 Plates SA 387 Grade 11 SA 387 Grade 22 Tensile strength, ksi [MPa] 60 to 85 [415 to 585] 60 to 85 [415 to 585] Yield strength min. ksi [MPa] 35 30 Elongation in 8 in.
