Oil & Gas: Used in downhole and surface equipment, as well as in offshore drilling platforms.
Marine Engineering: Perfect for seawater cooling systems, marine exhaust systems, and underwater structures.
Pollution Control: Employed in scrubbers, flue-gas desulfurization systems, and other pollution control equipment.
Nuclear Industry: Used in fuel reprocessing and other highly corrosive nuclear environments.
Advantages
Long Service Life: Durability in harsh environments translates to reduced maintenance and downtime.
Versatility: Suitable for a wide range of industrial applications due to its comprehensive resistance to corrosion.
Cost-Effective: Although an advanced material, its longevity and reliability make it a cost-effective choice in the long run.
Customization: Available in various thicknesses and sizes to meet specific project requirements.
Manufacturing Process
Melting: The alloy is melted using vacuum induction melting (VIM) or electric arc furnace (EAF) techniques to ensure purity.
Casting: The molten alloy is cast into slabs or ingots, depending on the required product form.
Hot Rolling: The ingots are hot-rolled into plates of varying thicknesses.
Annealing: Plates undergo annealing to relieve internal stresses and enhance ductility.
Pickling: The plates are pickled to remove surface oxides and impurities.
Inspection: Final inspection for dimensional accuracy, surface quality, and mechanical properties.
Operating Instructions
Handling: Use appropriate handling tools to avoid surface damage.
Welding: Use standard welding techniques like TIG or MIG. Preheat the plate to prevent cracking.
Machining: Employ carbide tools for machining, maintaining a slow feed rate to avoid work hardening.
Forming: Cold forming is possible but requires careful handling to avoid cracking.
Precautions
Storage: Store in a dry environment to prevent surface oxidation before use.
Welding: Avoid contamination by ensuring cleanliness in the welding area.
Machining: Use adequate coolant to prevent overheating.
Safety: Use protective gear when handling and processing the material to avoid injuries.
