Marine Grade - Stainless steel 316 (A4)
316 (A4) fasteners are made from Type 316 stainless steel, which is known for its excellent corrosion resistance, particularly against chloride environments, such as those found in marine and coastal areas. The "A4" designation indicates that these fasteners belong to the A4 series, which is a classification under the ISO metric standard for fasteners, specifically for high corrosion resistance applications.
Key Characteristics of 316 (A4) Fasteners:
- Material Composition: 316 stainless steel includes molybdenum, which enhances its resistance to pitting and corrosion in environments containing chlorides and other harsh chemicals.
- Corrosion Resistance: Highly resistant to rust, oxidation, and corrosion, making them ideal for use in marine environments, chemical processing, and other corrosive applications.
- Mechanical Properties: They offer good strength and toughness, even at elevated temperatures.
- Applications: Commonly used in marine hardware, chemical plants, food processing facilities, and other environments where exposure to corrosive agents is a concern.
- Magnetic Properties: Typically non-magnetic in annealed conditions but may become slightly magnetic when worked or cold-formed.
- Standards: Often conform to ISO, DIN, or ASTM standards, ensuring quality and consistency in industrial applications.
These fasteners come in various forms, including bolts, nuts, screws, and washers, and are available in multiple sizes to suit different applications. They are highly valued for their durability, reliability, and longevity in demanding environments.
