Perforated stainless steel sheet is stainless steel sheet that has been punched with a several holes to give you a nominated pattern. The pattern can vary depending on the hole size, distance between holes and the thickness of the material.

Perforated stainless steel sheet has many various uses, it can be used for oil filters, or the raw material of metal basket especial the sterilization trays, as fencing screen for expressway, railway and other construction facilities used in workshops as well as other constructions as sound isolation sheet decorative sheet for stairs, environmental tables and chairs sifting in grains, feed and mines also used in making of kitchenware such as fruit basket, food cover.

Perforated stainless steel sheet is essentially a low carbon steel which contains chromium at 10% or more by weight. The chromium content of the steel allows the formation of a rough, adherent, invisible, corrosion-resisting chromium oxide film on the steel surface. If damaged mechanically or chemically, this film is self-healing, providing that oxygen, even in very small amounts, is present.

Stainless steels can be divided into three basic groups based on their crystalline structure: austenitic, ferritic, and martensitic.

- 304 Low carbon modification of type 302 for restriction of carbide precipitation during welding.

- 304L Extra-low carbon modification of type 304 for further restriction of carbide precipitation during welding.

- 316 Higher corrosion resistance than types 302 and 304, high creep strength.

- 316L Extra low carbon modification of types 316, used in welded construction where intergranular carbide precipitation must be avoided.

- 321 Stabilized for welds subject to severe corrosive conditions and for service from 800 to 1600F.
