Steel S30900 (Mat.No. 1.4828*, AISI 309)
Designation by Standards
Chemical Composition (in weight %)
Description
This steel is known for good strength and oxidation resistance in continuous service temperatures up to 1093oC. It is superior to 304 stainless in both strength and corrosion resistance.
Applications
Oven linings, boiler baffles, fire box sheets, furnace components and other high temperature containers, parts for steam boiler lining, and their operation.
Physical properties (avarage values) at ambient temperature
Modulus of elasticity [103x N/mm2]: 200
Density [g/cm3]: 8.0
Thermal conductivity [W/m.K]: 15.6
Electric resistivity [Ohm mm2/m]: 0.78
Specific heat capacity[J/g.K]: 0.50
Magnetisable: No
Coefficient of Linear Thermal Expansion 10-6oC-1
Soft Annealing
Heat to 1050-1150oC, then quenching in water. Structure is austenite.
Hardening
This alloy does not respond to heat treatment. Cold work will cause an increase in both hardness and strength.
Forging
Hot forming temperature: 1150-950oC.
Machinability
This alloy machines similarly to type 304 stainless. Its chips are stringy and it will work harden rapidly. It is necessary to keep the tool cutting at all times and use chip breakers.
Corrosion Resistance
This steel is slightly more resistant to corrosion than 304 stainless. It will resist nitric, nitric-sulfuric, acetic, lactic and citric acids in mild dilutions. It is recommended for use in oxidizing but not reducing compounds.
Welding
Most of the austenitic stainless steels can be readily welded using fusion or resistance methods. Oxyacetylene welding is not recommended. Filler metal should be AWS E/ER 309 or 309L.
