What is SUS316 stainless steel?
SUS316 is a molybdenum-containing austenitic stainless steel second only to SUS304 in its application range. Its corrosion resistance is generally superior to SUS304, especially in chloride-containing environments, and it offers strong resistance to pitting and crevice corrosion. GNEE offers SUS316 in various product forms, including SUS316 stainless steel plate, SUS316 stainless steel pipe, and SUS316 stainless steel coil. Custom specifications are also available.

Heat Resistance:
SS 316 can withstand high temperatures, offering resistance to oxidation up to 870°C (intermittent) and 925°C (continuous). However, it's not recommended for long-term use at higher temperatures in corrosive environments.
Weldability:
SS 316 is generally considered weldable, though the specific welding process may vary depending on the application.
Machinability:
SS 316 has moderate machinability, but it's not as readily machinable as some other stainless steel grades.
What is the difference between 304 and SUS316?
The primary difference between 304 and 316 stainless steel lies in their molybdenum content. 316 stainless steel contains molybdenum, which enhances its corrosion resistance, particularly in chloride-rich environments like saltwater. While both are austenitic stainless steels, 316 generally offers superior resistance to corrosion and pitting, making it suitable for more demanding applications.
What is the price of SUS316 stainless steel?
SUS316 stainless steel products come in a variety of forms, including SUS316 plates (hot-rolled and cold-rolled), SUS316 bars (round and square bars), and SUS316 pipes (seamless and welded). Prices vary depending on price fluctuations of raw materials like nickel, chromium, and molybdenum, product specifications (such as dimensional tolerances), processing complexity (such as special surface treatments), and market supply and demand.
