Type 304
One of the most widely used and oldest of the stainless steels. This was originally called 18-8 which stood for its chromium and nickle content. It possess an excellent combination of strenght, corrosion resistence and fabricability.

Type 316
This austenitic has an added molybdenumcontent to increase its resistance to corrosion, when compared to other 300 series alloys. It will resist scaling at temperatures up to 1600 F. 316 is used in the marine industry for its resistance to corrosion. It is widely used in the marine/ pharmaceutical and laboratories

Type 430
Is a simple corrosion and heat resisting grade and finds application in areas where a mildly corrosive conditions occur or where scaling resistance at moderate temperatures is required.
