Shipping is included, so direct purchase without comments is welcome. The composition of SUS316 is: Chromium (Cr) 16.00-18.00%, Nickel (Ni) 10.00-14.00%, Molybdenum (Mo) 2.00-3.00%, and Carbon (C) content is 0.08% or less. SUS316 is a type of austenitic stainless steel, a steel grade that adds nickel and molybdenum to SUS304. Molybdenum has the function of repairing the passive film, so it has better corrosion resistance and pitting corrosion resistance than SUS304. SUS316 is often used in products that require corrosion resistance, such as marine parts, chemical tanks, food equipment, general chemical equipment, and nuclear power applications.
