2.304L Stainless Steel escription
Alloys 304L exhibits excellent corrosion resistance and has a high ease of fabrication, outstanding formability.
The austenitic stainless steels are also considered to be the most weldable of the high-alloy steels and can be welded
by all fusion and resistance welding processes.
Alloy 304L Stainless Steel is used in a wide variety of home and commercial applications, including:
- Food processing equipment, particularly in beer brewing, milk processing, and wine making
- Kitchen benches, sinks, troughs, equipment, and appliances
- Architectural trim and molding
- Automotive and aerospace structural use
- Construction material in large buildings
- Chemical containers, including for transport
- Heat exchangers
- Nuts, bolts, screws, and other fasteners in the marine environment
- Dyeing industry
- Woven or welded screens for mining, quarrying & water filtration
3.304L Stainless Steel BLIND Flange Packaging
Steel flanges must be packed with seaworthy packing method then delivery to customers, usually the
packing way include wooden box, wooden pallet, iron & steel cage, iron & steel pallet etc.
Because of the normal wooden boxes or wooden pallets have to do fumigation treatment, we usually
use plywood pallet or plywood case or box to pack steel flanges without fumigation treatment.
Whatever plywood or iron & steel packing way, they must be seaworthy, strong, waterproof and easy for
loading and unloading.
