Specification
Product description:
It has the lower nickel content of SS309S compared to SS310S improves resistance to hydrogen sulfide attack at high temperatures.It is tough and ductile and can be readily fabricated and machined.SS309S has the lower carbn than SS309 and is recommended for applications where sensitization and subsequent corrosion by high temperature gases or condensates during shutdown may pose a problem.
309S is used for its high-temperature oxidation resistance to hydrogen sulfide attack for applications such as furnace parts,firebox sheets,high-temperatre containers,catalytic converters,exhaust systems and so on.
Corrosion Resistance:It is difficult to discuss every combination in detail because of many possible variations involved-temperature,corrosive environment,alloy composition,time,operating,practice and so on.So the following data should be used as guideline only.
Annealing:Annealing is achieved by heating to between 1030℃ and 1150℃ for 90 minutes per 25mm thickness followed by water quenching.Annealing will ensure that any carbide preciptitates are takend back into solution.
Welding:SS309 can be satisfactorily welded and brazed by all methods,giving a tough weld.SS309S should be specicied if carbide preciptitation can have derrimental effect on the performance of the steel under operating conditions.
