To provide more detailed specifications for Forged Stainless Steel Flanges, please clarify what specific information you are looking for. "More specifications" could include:

• Pressure Class/Rating: What pressure ratings are available (e.g., ASME Class 150, 300, 600; PN10, PN16, PN25 etc. for EN/DIN)?
• Facing Type: What type of flange face is required (e.g., Raised Face (RF), Flat Face (FF), Ring Type Joint (RTJ), Lap Joint (LJ))?
• Drilling/Bolt Hole Patterns: Details on bolt circle diameter, number of holes, and hole size specific to pressure classes and sizes.
• Surface Finish of Facing: Roughness requirements.
• Dimensions: Detailed dimensions for each flange type and size (e.g., outside diameter, bolt circle diameter, hub diameter, thickness). This is usually found in the respective standards (e.g., ASME B16.5 tables).
• Material Chemical Composition: Specific percentage ranges for elements like Carbon, Chromium, Nickel, Molybdenum, Nitrogen for each stainless steel grade.
• Mechanical Properties: Minimum tensile strength, yield strength, elongation, and hardness for each grade.
• Corrosion Resistance: Specific test methods or ratings for intergranular corrosion, pitting resistance equivalent number (PREN) for duplex grades.
• Testing Requirements: Hydrostatic testing, non-destructive testing (NDT) like liquid penetrant (PT) or ultrasonic (UT), impact testing.
• Heat Treatment: Specific heat treatment requirements (e.g., solution annealing for austenitic stainless steels).
• Marking Requirements: How flanges are marked with grade, size, pressure class, manufacturer.
• Quality Control/Inspection
