Stainless steel 316 is a highly corrosion-resistant and versatile stainless steel alloy. It belongs to the austenitic class of stainless steels, which are known for their excellent corrosion resistance, high ductility, and low carbon content.

The composition of stainless steel 316 typically includes around 16-18% chromium, 10-14% nickel, and 2-3% molybdenum. The addition of molybdenum enhances its resistance to pitting and crevice corrosion, especially in chloride-containing environments, making it suitable for use in marine environments and applications involving exposure to corrosive chemicals.

Stainless steel 316 offers excellent strength and toughness, good formability, and weldability. It is widely used in various industries, including marine, chemical processing, pharmaceuticals, food and beverage, medical devices, and architecture. It is often used in applications such as marine equipment, valves, pumps, heat exchangers, surgical instruments, and architectural components.

Compared to stainless steel 202, stainless steel 316 provides superior corrosion resistance, particularly in aggressive environments. It is considered one of the most corrosion-resistant stainless steel grades available.
