*Grade 304 Stainless Steel
Grade 304 is very versatile and is widely used in a variety of outdoor applications including electrical enclosures, auto moulding and trim, kitchen appliances, storage tanks, and piping.
Its combination of 18% chromium and 8% nickel also give it good resistance to moderately acidic or caustic solutions, making it suitable for non-severe applications such as kitchen and food environments. It’s a product that is easy to fabricate, easy to clean and comes in a variety of finishes and appearances.
**Marine Grade 316 Stainless Steel
Marine grade 316 stainless steel is similar to Grade 304 with one notable exception. As well as chromium and nickel, Marine grade 316 also contains 2% to 3% of molybdenum, a hard, silver white metallic element used to toughen steels and increase corrosion-resistance in nickel alloys.
The addition of this ingredient gives Marine grade 316 superior corrosion resistance to other chromium-nickel steels when exposed to chemical corrosives such as seawater and brine solutions. Like Grade 304, it is also durable, easy to fabricate, clean, weld and finish, but unlike Grade 304, it provides greater protection from salt spray and brine.
Marine grade 316 is also much more resistant to solutions of sulfuric acid, chlorides, bromides, iodides, and fatty acids at high temperature and is commonly used in industrial applications involving chemical processing. Due to its non-reactive qualities, it is also used in the manufacture of medical surgical instruments and in the manufacture of pharmaceuticals where excessive metallic contamination must be avoided.
