SPECIAL FLANGE 36" 600 REINFORCED LWN RF L=697mm WITH PAD CONNECTION
Material Specification
Material: A350 LF2 CL.1 - Carbon Steel
Product Overview
ASTM A350 Grade LF2 is a general carbon steel typically supplied in Normalised, Normalised and Tempered, or Quench and Tempered condition. This material features moderate strength and impact toughness, making it ideal for flange and fitting manufacturing, as well as applications requiring cold temperature service where corrosion resistance is not critical.
Standards
ASME B16.5, EN1092
Material
ASTM A105, A350, A266 etc
Size
1/2" - 24"
Surface Treatment
Anti-rust oil, clear lacquer, Black lacquer, Yellow lacquer, Hot-dipped Galvanized
Manufacturing Process
Forging
Forging temperature range: 900 – 1200°C. Soak times should be minimized to prevent heavy scaling while ensuring the center reaches furnace temperature. Post-forging, pieces should cool in still air.
Heat Treatment
Normalising: Heat to 860-920°C for duration based on ruling section, then air cool (if required)
Hardening: Heat to 890-960°C for duration based on ruling section, then water quench
Tempering: Re-heat to minimum 590°C as required for final properties. Hold for duration based on ruling section and cool in still air
Machinability
ASTM A350 LF2 offers good to very good machinability depending on condition. Standard machining operations including sawing, turning, broaching, and milling can be performed effectively using manufacturer-recommended speeds and feeds.
Weldability
ASTM A350 LF2 is readily weldable using any standard welding technique.
