The 316L stainless steel wide flange beam is an austenitic metal. It is an alloy made up with high concentrations of molybdenum, chromium and nickel. This combination makes this grade of steel very tough and corrosion resistant, especially in regard to crevice corrosion and pitting when in chloride environments. It also has great tensile, creep and stress-rupture strengths when placed in high temperatures. This grade of steel can be formed using a variety of methods, such as welding, machining, cold forming and forging. Heat treatment cannot be used to harden 316 steels.
This product can be used in a variety of applications, including chemical process equipment, condensers, pollution control equipment, heat exchangers, evaporators, paper machinery, boat trimmings and lab equipment. It’s frequently used in a warm sea water environment because it is a “marine grade stainless steel”. In general, 316 stainless steels are more resistant to atmospheric environments than 304 alloys because it has more molybdenum and chromium. This metal has a great level of oxidation resistance when being continuously serviced at 1700 degrees F and intermittently at 1600 degrees F.
The weldability of the 316 stainless steel wide flange beam is excellent. All methods of standard fusion welding can be used either without or with filler metals. The sections that have been heavily welded should be post-weld annealed to achieve max corrosion resistance. The temperature range that should be for annealing is between 1900 and 2100 degrees F. This process can’t be used to harden 316 alloys. The forging temperature that should be used for 316 alloys should be between 2100 and 2300 degrees F. Forging should be done at a temperature below 1700 degrees F.
