Properties of AISI 330 Stainless Steel

330 SS Cold Forming

SS 330 is quite ductile and forms easily. The addition of molybdenum and nitrogen implies more powerful processing equipment may be necessary when compared with the standard 304/304L grades.

330 SS Hot Forming

Working temperatures of 1652 – 2102°F (900 – 1150°C) are recommended for hot working processes. Do not work this SS below 1742°F (950°C). If the final forming temperature falls below this threshold, a solution anneal of 1976 – 2156°F (1080 – 1180°C) is necessary. Rapid quenching is required.

330 SS Machining

The cold work hardening rate of SS 330 makes it less machinable than 410. Low speeds and constant feeds will minimize this SS's tendency to work harden. Tougher than 304 stainless with a long stringy chip, the use of chip breakers is recommended.

330 SS Welding

SS 330 can be readily welded by most standard processes. A post weld heat treatment is not necessary. All common fusion and resistance methods except oxyacetylene welding have proven successful. Use AWS E/ER 330 filler metal for best results.

330 SS Heat Treatment

330 stainless steel does not respond to heat treatment. Cold work will cause an increase in both hardness and strength. 1850-2050 F (1010-1121 C), followed by rapid cooling.
