READILY MACHINABLE STAINLESS STEEL
Benefitting from being the most machinable of all austenitic stainless steels available today, Type 303 stainless steel’s machinability is improved due to the presence of sulphur in the alloying process. However, the presence of sulphur slightly reduces the alloys overall toughness and results in a decrease in corrosion resistance. Used in a variety of engineering applications, Type 303, as with most austenitic grades, has excellent toughness though weldability is poor.
Corrosion resistance of the alloy is good in mild environments.
Typical commercial applications for Type 303 stainless steel alloy include:
- Electrical switchgear components
- Aircraft components
- Gears, bushes, shafts, fastenings
- Very good machinability but reduced formability
- Welding not recommended
- Lower corrosion resistance than 1.4301
- Excellent toughness
