S30400 round bar is one of the most widely utilized 18/8 stainless steel alloys in existence. Industrial Metal Supply offers ASTM A479 UNS S30400 Rod in a wide range of diameters to fit your exact application needs. With over 400,000 total square feet of warehouse and storage space in China, the UNS S30400 Round Bar Manufacturer HT PIPE has the capacity and capabilities to service your ASTM A276 Type 304 bar stainless steel needs.

 

304 is the most versatile and widely used of all stainless steels. Its chemical composition, mechanical properties, weldability and corrosion/oxidation resistance provide the best all-round performance stainless steel at relatively low cost. Stainless Steel 304 Round Bar also has excellent low-temperature properties and responds well to hardening by cold working. If the potential for intergranular corrosion in the heat-affected zone exists, 304L is recommended. ASTM A276 304 Stainless Steel Bar is a versatile, anti-rusting and heat resistant steel for general use. And it is used mainly in the building, plumbing and chemical industries.

 

The passivated oxide layer formed on the surface of 304 SS Round Bar prevents decay by oxidation. The free chromium present on the surface of these bars reacts with oxygen to form a self-healing layer on the S30400 round bar, thereby effectively preventing the 304 SS Bar from getting corroded by oxidation. However, amongst all the attractive properties, what really stands out is that the SS 304 Flat Bar can be used in cryogenic environments. Unlike some alloy steels or some stainless steel grades, the 304 SS Flat Bar is able to retain properties such as excellent mechanical strength as well as toughness, despite exposure to cryogenic temperatures.
