Common Grades

Non-Hardening, Chrome Nickel Steels

303 - A free machining version of 304 with only slightly less corrosion resistance and physical properties.

304 - The most popular type of stainless, exhibiting good corrosion resistance, formability, and ease of welding by all common methods.

304L - Lower carbon version of 304. Used to minimize carbide precipitation during welding. Physical properties somewhat less than 304.

310 - Heat resistant. Good resistance to thermal fatigue due to cyclic heating; resists scaling up to 2050F.

316 - Superior corrosion resistance and higher strength at elevated temperatures than 304. Frequently used in marine applications. Resistant to creep at high temperatures.

316L - Lower carbon version of 316. Used to minimize carbide precipitation during welding.

Sheet & Plate Finishes

No. 1 - Hot-rolled, annealed, and descaled. Generally used in (HRAP) applications in which resistance to corrosion and heat is more important than smoothness or finish appearance.

No. 2B - Annealed, descaled and cold-rolled with a bright finish. Commonly used for all but difficult deep drawing applications. This finish is more readily polished than No. 1.

No. 4 - General purpose, polished finish one side. Widely used in applications requiring a superior cosmetic finish, such as restaurant and kitchen equipment, dairy equipment, etc.

No. 8 - The most refective finish commonly available. Surface is essentially free of grit lines from preliminary grinding operations. Commonly used for press plates, as well as small mirrors and reflectors.
