316L Stainless Steel Square Bar

Designed for use in tanks, supports and frames, enclosures, housings, engine, machinery components, and marine applications.

Product Description

The 316L stainless steel square bar is a grade of metal that is alloyed with high instances of chromium, nickel and molybdenum. This combination makes this stainless steel very strong and resistant to corrosion. In this area, 316L stainless steels are better than 304 stainless steels. The 316L version is also tougher than the 316 alloys. It is a non-magnetic metal, allowing it to be used for moving parts and instruments. It is easy to forge, machine and cold work. 316L steels have excellent drawability, formability and weldability. Because of its ease of use and durability, it is commonly used in industries, such as food, paper, chemical, dyeing, boating, pharmaceutical and architecture.

Some of the applications that this steel is frequently used for include boat fittings, valves, heat exchangers, condensers, pollution control equipment, food prep equipment and chemical processing equipment. It is typically resistant to pitting and crevice corrosion, except for in warm chloride environments that are over 122 degrees F. It is, however, resistant to potable water with ambient temperatures that has no more than 1000g of chloride. It is resistant to warm salt water, which is why it’s considered marine grade stainless steel.

This grade of metal is also has good oxidation resistance when receiving intermittent service no higher than 1600 degrees F and in continuous service at no higher than 1700 degrees F. Compared to other grades of stainless steel, 316L steels have a higher resistance to carbide precipitation.
Standard fusion methods of welding can be used for 316L stainless steel. Filler metals can be used during the welding process. No post-weld annealing is needed to maintain corrosion resistance.
