What is Stainless Steel 309/309S Flanges ?
Stainless steel 309/309S flanges are extremely ductile and strong. The chemical composition of these flanges is extremely robust and tough. The alloy 309 has less carbon content which improves the stability and weldability of the grade. Stainless steel 309/309S flanges are commonly used as boilers and heat exchangers because of their excellent chemical and mechanical properties. The only difference between grade 309 and 309S is its carbon content.
The tensile strength and yield strength of these flanges is extremely high. The minimum tensile strength of these flanges is 620 MPa (89000 psi) whereas the yield strength of these flanges is 310 MPa ( 45000 Psi). These flanges are commonly applicable in industries like Aerospace, Petroleum refineries, Chemical Processing, Oil & Gas, Pharmaceutical, Thermal Processing, etc. Grade 309/309S is capable of bearing high heat, bad weather conditions and chloride involved environment.
