General Descriptions:

Type 302 - A slightly higher carbon version of type 304, most commonly found in strip and wire forms. More corrosion resistant than 301 due to higher nickel content. Non-magnetic in annealed form, slightly magnetic when cold formed.

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 nickel content. It possesses an excellent combination of strength,

Type 316 - This austenitic stainless steel has an added molybdenum content 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.

Type 17-4PH - General purpose, precipitation-hardening stainless steel, Low temperature (1000 deg F approx) “age hardening” produces superior hardness/strength without distortion or scaling.
