Description

What is 309S Stainless Steel ?

309S stainless steel has better corrosion resistance and high temperature resistance. It can withstand repeated heating below 980 ℃, and has high high temperature strength, oxidation resistance and carburization resistance.

It is widely used in boilers, energy (nuclear power, thermal power, fuel cells), industrial furnaces, incinerators, heating furnaces, chemical, petrochemical and other important fields.

309S Stainless Steel Welding:

Grade 309S stainless steel can be welded using most of the resistance and fusion methods. Oxyacetylene welding is not preferred for this steel.


309S Stainless Steel Hot Working:

Hot working of grade 309S stainless steel can be done at 1177°C (2150°F) and reheated at 982°C (1800°F). This process is followed by rapid cooling to obtain maximum corrosion resistance.


309S Stainless Steel Cold Working:

Grade 309S stainless steel can be drawn, headed, upset and stamped, although this steel has high work hardening rate. However, it has be fully annealed after cold-working to reduce internal stress.


309S Stainless Steel Annealing:

Grade 309S stainless steel can be annealed at temperature ranging from 1038 to 1121°C (1900 to 2050°F) and then quenched with water.


309S Stainless Steel Hardening:

Grade 309S stainless steel is unresponsive to heat treatment. The hardness and strength of the steel can be increased through cold working.


309S Stainless Steel Applications:

The following are the major applications of grade 309S stainless steel:

Oven linings, Boiler baffles, Fire box sheets, Furnace components, Other high temperature containers.
