Stainless Steel Decorative Armillary Sphere

304 Stainless Steel

304 stainless steel has a high resistance to rust. It will withstand corrosion from most oxidizing acids and is often used for kitchen and food applications. Nowadays, it is also used in decorative stainless steel products, both for indoor and outdoor application.However, it is susceptible to corrosion from chloride solutions (notably saline environments with high amounts of sodium chloride).

304 grade is the most common form of stainless steel used around the world. It contains between 16 and 24 percent chromium and up to 35 percent nickel—as well as small amounts of carbon and manganese. The most common form of 304 stainless steel is 18-8, or 18/8, stainless steel, which contains 18 percent chromium and 8 percent nickel.

316 Stainless Steel

316 grade is the second-most common form of stainless steel. It has almost the same physical and mechanical properties as 304 stainless steel and contains a similar material make-up. The difference is that 316 stainless steel incorporates about 2 to 3 percent molybdenum, which increases corrosion resistance—particularly against chlorides and other industrial solvents. Alternative 300-series grades can contain up to 7 percent molybdenum.

316 stainless steel is commonly used in many industrial applications involving processing chemicals, as well as high-saline environments such as coastal regions and outdoor areas where de-icing salts are common. Due to its non-reactive qualities, 316 stainless steel is also used in the manufacture of medical surgical instruments.

Versatile applications

Both 304 and 316 stainless steels (as well as other 300-series grades) use nickel to maintain an austenitic composition at lower temperatures. Austenitic steels ensure a versatile balance of strength, workability and corrosion resistance, making them ideal for outdoor architectural and landscape applications. The benefits of stainless steel include a long service life that will retain an attractive, clean finish with low maintenance cost. It also maintains a high value if and when equipment and parts need to be decommissioned.

Reliance Foundry offers a selection of stainless steel bollards that can be mounted for various fixed, removable, fold-down and retractable applications. Our stainless steel products use only 316 grade material for the best performance in almost any North American environment.

Mechanical properties of 304 grade stainless steel

What is the Difference Between 304 and 316 SS?

In a nutshell, type 316, is more resistant to corrosion from salt water, making it the best material for use on and near the ocean. 

Stainless steel is an alloy that contains at least 50% iron and 10% chromium. The chromium inhibits corrosion and thus plays a part in defining stainless steel.

Stainless steel alloys are grouped according to the structure of their crystals. Adding nickel creates the structure used in marine applications, called austenitic.

By adding more nickel and 2% molybdenum to 304 stainless, you get type 316, which has the best corrosion resistance among standard stainless steels. It resists pitting and corrosion by most chemicals, and is particularly resistant to salt water corrosion.

SHIPPING

Modes of  Shippment

Ground, Ship and Air

Ground:

Land or "ground" shipping can be by train or by truck. Ground transport is typically more affordable than air, but more expensive than sea especially in developing countries like India, where inland infrastructure is not efficient.

Shipment of cargo by trucks, directly from the shipper's place to the destination, is known as a door to door shipment and more formally as multimodal transport. Trucks and trains make deliveries to sea and air ports where cargo is moved in bulk.

Ship:

Much shipping is done aboard by actual ships. On rivers and canals, barges are often used to carry bulk cargo.

Air:

Cargo was transported by air in specialized cargo aircraft and in the luggage compartments of passenger aircraft. Air freight is typically the fastest mode for long distance freight transport, but also the most expensive.
