Overview
S31254 is an austenitic steel designed for maximum resistance to pitting and crevice corrosion. With high levels of chromium, molybdenum and nitrogen, It is especially suited for high chloride environments such as brackish water, seawater, pulp mill bleach plants and other high-chloride process streams. In new construction, S31254 has been found in many cases to be technically adequate and much less costly substitute for nickel-based alloys and titanium. It is readily fabricated and welded.
Application
1. Ocean: marine structures, seawater desalination, seawater farming, seawater heat exchange, etc.
2. Environmental protection field: flue gas desulfurization device for thermal power generation, waste water treatment, etc.
3. Energy field: nuclear power generation, comprehensive utilization of coal, tidal power generation, etc.
4. Petrochemical field: oil refining, chemical and chemical equipment, etc.
5. Food field: salt making, soy sauce brewing, etc.
6. High concentration chloride ion environment: paper industry, various bleaching devices

Annealing
Annealing of this material should be performed at 1149-1204°C (2100-2200°F), which should be followed by a water quench.
Hot Working
Forging, upsetting and other operations relating to this material can be performed at 982 - 1149°C (1800 - 2100°F). It is recommended that temperatures do not exceed this range as it would result in scaling and reduction in the workability of the material. To re-attain maximum corrosion resistant properties, it is advisable to perform post-process annealing.
Cold Working
Cold working can be carried out using all the traditional methods; however the process would be tough due to its high work hardening rate. The result will provide the material with increased strength and toughness.
Package Process
1.with plastic cap to protect both ends
2.weaving bag wrapped outside the pipe
3.then pack into wooden case.
