304 Stainless Steel
Marco Specialty Steel offers the following products in type 304 stainless steel:
Principal Design Features: 304 stainless steel is one of the most widely used and oldest of the stainless steels. This was originally called 18-8 which stood for its chromium and nickel content. 304 steel possesses an excellent combination of strength, corrosion resistance and is easily fabricated. 304 is available in the widest variety of forms and sizes of any stainless steel.
Applications: The list of 304 stainless steel applications is endless. Almost every conceivable industry uses some of this material in some way. Everything from stovetops to heat exchangers to flatware to grating fasteners to chemical process vessels has been fabricated from 304 stainless steel.
Machinability: Slow speeds and heavy feeds will minimize this alloys tendency to work harden. Due to long stringy chips, the use of chip breakers is advisable. Many companies now offer premium machinability grades, such as CarTech with their Project 70 and 7000 series.
Welding: All fusion and resistance processes have been successfully employed in welding 304. AWS E/ER308 or 312 filler metal is recommended. For cleaner, stronger welds, may users choose 304L stainless steel which has a controlled low carbon content designed to reduce carbide precipitation at the weld boundaries.
