END USES
AISI 430 is currently the most used ferritic stainless steel grade in the world. The steel is ferromagnetic at ambient temperature and cannot be tempered. This steel contains an average content of Chromium and as such presents average resistance to corrosion.
The grade is used in a vast range of applications, especially for indoors. The presence of small amounts of sulphur can help the workability of this type of steel in mechanical machining for chip removal. Welding ability is reduced, because the material crystalline grain expands at high temperature in the welding points.
Some possible uses are: equipment for bars-restaurants, parts for the food industry, architectural decorative elements, parts for household appliances, vehicle accessories, parts for burners.
