copper perforated sheet 

Perforated Stainless Steel

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

Perforated Inconel and Monel

Inconel refers to a family of high strength nickel-chromium-iron alloys, e.g. Inconel 600 contains 72% nickel, 16% chromium and 8% iron. Other versions of Inconel exist, e.g. Inconel 750 has a small percentage of titanium and aluminum added for hardenability.

These alloys have exceptional anti-corrosion and heat-resistance properties and are used for a variety of extreme applications such as chemical processing, aerospace and marine engineering, pollution-control equipment, and nuclear reactors.

Another high nickel content alloy is Monel, its composition is 65-70% nickel, 20-29% copper and it further contains a/o iron and manganese

Monel is highly corrosion resistant and some alloys can withstand a fire in pure oxygen. Monel is used for marine engineering, chemical and hydrocarbon processing equipment, valves, pumps, shafts, fittings, fasteners, and heat exchangers. It is also used as part of metal instruments and frames of eyeglasses. Some alloys are completely non-magnetic and are used for anchor cable aboard minesweepers, housing magnetic field measurement equipment, and have applications in the oil drilling industry.

Due to the high nickel content in Inconel and Monel, these alloys are more expensive than stainless steel.
