| Melting Practice | Alloy shall be produced by electron beam cold hearth or plasma arc cold hearth melting method, or multiple melted with the final melting cycle under vacuum. When multiple melts occur, the first melt shall be made using a vacuum consumable electrode, non-consumable electrode, electron beam cold hearth, or plasma arc cold hearth melting practice. The subsequent melt or melts shall be made using vacuum arc remelting (VAR) practice. Alloy additions are not permitted in the final remelt cycle. |
| Condition | Sheet and Strip: Hot rolled with or without subsequent cold reduction, annealed, descaled, and leveled, having a surface appearance comparable to a commercial corrosion-resistant steel No. 2D finish. Plate: Hot rolled, annealed, descaled, and flattened, having a surface appearance comparable to a commercial corrosion-resistant steel No. 1 finish. Plate products shall be produced using standard industry practices designed strictly for producing plate stock to the procured thickness. Bar, billet, forgings, or forging stock shall not be supplied in lieu of plate. |

Key Properties
Excellent Corrosion Resistance: Especially in seawater and oxidizing environments.
Good Formability: Allows for easy fabrication and shaping into complex parts.
Weldability: Can be readily welded using appropriate techniques.
Biocompatible: Suitable for medical implants and instruments.
Good Strength-to-Weight Ratio: Offers strength and lightweight properties.
Packing
Packed on plywood pallets or in boxes.
Application
Heat exchangers: Its resistance to seawater corrosion makes it ideal for heat exchanger tubing and plates in desalination plants, offshore platforms, and marine vessels.
Marine hardware: This material is used for boat fittings, fasteners, and rigging components due to its corrosion resistance and lightweight properties.
Piping systems: Ideal for seawater piping systems and other marine applications where corrosion resistance is crucial.
Chemical tanks and vessels: Its resistance to various acids and chemicals makes it suitable for storage and processing equipment in the chemical industry.
Process piping: Used for piping systems handling corrosive fluids and chemicals.
Reactor vessels: Its corrosion resistance and high-temperature capabilities make it worthwhile for chemical reactor vessels.
Medical instruments: Due to their biocompatibility and corrosion resistance, they are used for surgical instruments, implants, and dental tools.
Orthopedic implants: Though less common than Ti-6Al-4V ELI, Grade 2 can be used for less load-bearing applications like suture anchors or as coatings on other implant materials.
Architectural cladding and roofing: Its aesthetic appeal, corrosion resistance, and durability make it suitable for architectural applications.
Automotive exhaust systems: Used for exhaust pipes and mufflers due to their high temperature and corrosion resistance.
Power generation: Due to its corrosion resistance and heat transfer properties, it is used in power plants’ condenser tubing and other components.
