Tips

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. The more chromium, the more corrosion-resistance.  But chromium is not the only factor in corrosion resistance. Many other elements are added to enhance the properties of a particular grade and type of 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. Austenitic stainless steels are identified by their 300-series designation. Most of the stainless produced today is type 304, a low-carbon variation which is also called 18-8, because it's made of 18% chromium and 8% nickel. Type 304 has good resistance to corrosion by a great number of chemicals. Consequently, it satisfies a broad demand for adequate performance at an affordable price. But there are a number of marine applications where 304 and other 300-series types are inadequate.

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.

Dual Certification

It is common for 304 and 304L to be stocked in "Dual Certified" form, particularly in plate and pipe. These items have chemical and mechanical properties complying with both 304 and 304L specifications. Such dual certified product does not meet 304H specifications and may be unacceptable for high temperature applications.

Applications

Typical applications include:

  Food processing equipment, particularly in beer brewing, milk processing & wine making.

    Kitchen benches, sinks, troughs, equipment and appliances

    Architectural panelling, railings & trim

    Chemical containers, including for transport

    Heat Exchangers

    Woven or welded screens for mining, quarrying & water filtration

    Threaded fasteners

    Springs

 

Types 304 and 304L exhibit excellent resistance to corrosiveenvironments such as the chemical, textile and petroleum industries.Type 304 and 304L are found suitable in the food and dairy industries as well as excelling in rural and industrial atmospheric exposure.By reducing the carbon content in Type 304L, welding operations willnot cause carbide precipitation that can lead to intergranular corrosion. Themaximum temperature  to which Type 304 can be exposed continuously without appreciable scaling is about 1650 °F (899 °C).For intermittent cyclic exposure, the maximum exposure temperature

is about 1500 °F (816 °C).Type 304 is non-hardenable by heat treatment.Annealing: Heat to 1900 – 2050 °F (1038 – 1121 °C), then cool rapidly.Thin strip sections may be air cooled, but heavy sections should be waterquenched to minimize exposure in the carbide precipitation region.Stress Relief Annealing: Cold worked parts should be stress relieved at750 °F (399 °C) for 1/2 to 2 hours.High hardness and strength  are achieved through cold working. In the annealed condition, Types 304 and 304L are very ductile and can be cold worked easily by roll forming, deep drawing, bending, and other common fabricating methods. Since the material work hardens rapidly, in-process annealing may be necessary to restore ductility and to lower hardness.Types 304 and 304L can be readily formed and drawn. The higher nickel versions of  Type 304 are well suited to severe forming applications involving multi-draw operations and forming of complex shapes. This is largely due to its combination of lower strength and lower work hardening rate.  As with all austenitic stainless steels,annealing or stress-relieving can be performed following fabrication.The austenitic class of stainless steels is generally considered to be weldable by the common fusion and resistance techniques. Special consideration is required to avoid weld “hot cracking” by assuring formation of ferrite in the weld deposit. Type 304 and 304L are generally considered to be the most common alloys of this stainless class. When a weld filler is needed, AWS E/ER 308, 308L or 347 are most often specified. Types 304 and 304L Stainless Steels are well known in reference literature and more information can be obtained in the following ways:

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.
