Description:
309S stainless steel pipe is an austenitic stainless steel with a high proportion of chromium and nickel, which has excellent oxidation resistance and heat resistance. Compared with ordinary stainless steel, 309S stainless steel pipe can maintain good mechanical properties at high temperatures and has strong resistance to oxidation and corrosion.
The difference between stainless steel 309 and 309S is the carbon content. Alloy 309S has significantly less carbon content, which reduces carbide precipitation and improves weldability.

Performance characteristics of 309S stainless steel pipe:
High temperature resistance: 309S stainless steel pipe can maintain stable strength and oxidation resistance at temperatures up to 1000-1100°C, and is suitable for high-temperature heating equipment.
Oxidation resistance: Due to its high chromium content, 309S stainless steel can resist oxidation corrosion in high temperature environments.
Corrosion resistance: 309S stainless steel pipe has good resistance to general corrosion, especially in high-temperature sulfur-containing environments, its corrosion resistance is more significant.
Processability: 309S stainless steel pipe has good weldability and processability, and is suitable for cutting, welding and forming.
Applications:
309s stainless steel is mainly used to make furnace materials, and is also widely used in important fields such as boilers, energy (nuclear power, thermal power, fuel cells), industrial furnaces, incinerators, heating furnaces, chemicals, petrochemicals, etc.
