Stainless Steel Flat Bar (SST-304, SST-316)

Stainless Type 304 is one of the most versatile and commonly used grades of stainless steel. It is a Chromium-Nickel austenitic alloy containing a minimum of 18% Chromium and 8% Nickel with a max of 0.08% Carbon. It cannot be hardened by heat treatment but cold working can produce higher tensile strengths. The Chromium and Nickel alloy provide Type 304 with corrosion and oxidation resistance far superior to steel or iron. It has lower carbon content than 302 which enable it to minimize chromium carbide precipitation due to welding and intergranular corrosion. It has excellent forming and welding characteristics. Type 304 has an ultimate tensile strength of 51,500 psi, yield strength of 20,500 psi and 40% elongation in 2”. Stainless steel type 304 comes in many different sizes and shapes including bar, angle, rounds, plate, channel and beams.  This steel is used in many industries for many different purposes. Some examples are food processing equipment, kitchen equipment and appliances, paneling, trims, chemical containers, fasteners, springs, etc.

Stainless Type 316 is a standard molybdenum-bearing austenitic stainless steel grade.  It is austenitic, nonmagnetic, and thermally non hardenable. The alloying element of molybdenum gives type 316 more corrosion resistance than steel and iron or even type 304 stainless steel. It is especially resistant to pitting and crevice corrosion in chemical, salt and acidic environments. As a result of these characteristics it is more resistant to marine environment. It has great welding and forming characteristics. The austenitic structure of this steel gives it excellent toughness. Stainless 316 has a tensile strength 80,000psi and elongation is 50%. Stainless steel type 316 comes in many different sizes and shapes including bar, angle, rounds, plate, channel and beams. This type of stainless steel is widely used where metal is exposed to harsh corrosive effects like those found in the textile, pharmaceutical and chemical industries.  It is also used in the nuclear, aerospace and aviation industries.
