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.

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.
