Introduction:
300 Series stainless steels
are classified as austenitic, and are hardenable only by cold working methods.
These grades of stainless have chromium (approx. 18 to 30%) and nickel (approx.
6 to 20%) as their major alloying additions. Type 304 is the most widely
used alloy of all stainless steels. 300 Series Stainless steel alloys resist
corrosion, maintain their strength at high temperatures and are easy to
maintain.
300
series grades are inventoried in in stainless steel plate, sheet, bar, pipe, tube and structural products.
Austenitic
Stainless Steel are mainly used in the following industries:
- Heat exchanger, Fertilizer Industry
- Chemical and petrochemical industry,
- Power generation and Environmental technologies
- Ship Making, Oil and gas applications,
- Mechanical and plant engineering and
- Construction and Building, Automotive industry
- Nuclear industry , Shipping industry
- Food processing industry , Coal gasification
- Fertilizer production, Environmental protection, Aerospace industry
The 300
Series Stainless Steel offers several advantages:
- one of
the most common steels, with the ability to be used in a variety of
applications.
- superior
corrosion resistant properties
- developed
for applications requiring extensive machining operations
- non-magnetic
properties
- scratch
resistant
- many
Finishing options: polishing, beveling, etc
