Continuous development may necessitate changes in technical data without notice. This datasheet is only valid for materials under the trademark Kanthal^®.

Kanthal^® SW 030 is a ferritic iron-chromium-aluminum alloy (FeCrAl alloy) for use in arc and flame spray systems. The alloy produces dense, well bonding coatings, resistant to high-temperature oxidation and corrosion.

Typical applications for Kanthal^® SW 030 are bond coats in high-temperature coating systems, protective coatings against sulphur-containing atmospheres and protective coatings against scaling of conventional low alloy steels.

Typical coating properties

Summary of results obtained when spraying with a conventional Arc Spray gun, using varying spraying parameters.

Deposition efficiency (%)	65-75
Hardness HV (300g)	160-270
Surface roughness (µm)	12-17
Porosity (%)	1-6*
Oxides (%)	5-15*

*) These results are obtained when using air as spraying gas. Also nitrogen has been used, resulting in lower rates of porosity and oxides.

Personnel working with thermal spraying should be aware of the hazards connected to the process. They should be familiar with the use of equipment regarding, i.e. eye, skin, hearing and respiratory protection.

Personnel should be familiar with safety regulations regarding the complete process, including spraying and th spray equipment used. This product contains elements, which in certain combinations may be dangerous to your health.
