Description
Heat resistant steel. The strength of this steel is a combination of good strength and corrosion resistance in temperatures up to 1149oC. Due to its relatively high chromium and nickel content it is superior in most environments to 304 or 309 stainless. Shows excellent sesistance to carburizing & nitriding.

Applications
Parts for heating furnaces, carburizing boxes, emission purifiers, annealing boxes, nitric acid industry.

Physical properties (avarage values) at ambient temperature
Modulus of elasticity [103 x N/mm2]: 190-210
Density [g/cm3]: 7.7-8.03
Thermal conductivity [W/m.K]: 14.2

Coefficient of Linear Thermal Expansion 10-6 oC-1

20-100oC 20-315oC 20-540oC 20-650oC 20-980oC
15.8 16.2 16.9 17.5 19.1

Soft Annealing
Heat to 1038-1121oC, water quench.

Hardening
This alloy does not respond to heat treatment. Cold work will cause an increase in both hardness and strength.

Forging
Hot forming temperature: 1170-950oC.

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
Good resistance to both reducing and oxidizing environments up to 1149oC. Also resistant to atmospheric and marine corrodants, molten, drawing, tempering, high speed and cyaniding salts.

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 310.

Cold working
Although this alloy has a high work hardening rate, it can be drawn, headed, upset, and stamped. Full annealing is required after cold work to remove internal stress.
