Marine-grade stainless steel, also known as marine stainless steel or marine-grade stainless, refers to a specific type of stainless steel that is highly resistant to corrosion in marine environments. The corrosive nature of saltwater and exposure to other harsh conditions make marine-grade stainless steel essential for marine applications.
Here are some grades of marine stainless steel:
316 stainless steel: This is the most widely used marine stainless steel grade. It offers excellent corrosion resistance, high strength, and good weldability. It is suitable for a wide range of marine applications, including boat fittings, marine hardware, and underwater components.
316L stainless steel: Similar to 316 stainless steel, but with lower carbon content to improve corrosion resistance in welded structures. It is often used in welded applications to prevent sensitization to corrosion.
2205 duplex stainless steel: This grade offers a higher level of corrosion resistance compared to 316 stainless steel. It has a dual-phase microstructure and provides excellent strength, making it suitable for offshore and marine applications.
