304 Stainless Steel Flat & Square Bar

304 is in the “Austenitic” group (or chrome-nickel series) of stainless steels. It is not hardenable by heat-treatment and it is not magnetic. Hardness is accomplished by cold-working, which may create some magnetism). Tougher and more ductile than most ordinary steels, 304 (and other austenitic), also has excellent mechanical properties and weldability and good corrosion resistance.

Typical Mechanical Properties – 304 Bar:

Tensile Strength (psi) 90,000
Yield Point (psi) 40,000
Elongation % in 2″ 50
Brinell Hardness 163
