FERROSAD low-carbon • cast-steel blasting shot •
Metalltechnik Schmidt GmbH + Co. is producing low carbon steel shot since more than 30 years. The 100% family-owned company is located close to Stuttgart and produces approx. 45000 tons of premium low carbon steel shot FERROSAD per year. A further interesting product of Metalltechnik is the aluminium shot ALUSAD
In 1960, after extensive laboratory testing, granules of steel were melted which had a carbon content of less than 0.1%. The liquid melt was heated to 1,700° C in 500 kg induction furnaces and atomised in a specially designed water jet.
The Metalltechnik Schmidt GmbH & Co. company was founded in 1967 at a time when market demand was lively and sales were increasing.
A new blasting shot works, equipped with the most up-to-date induction furnaces and technical facilities, was constructed in 1968 at its present location in Filderstadt-Plattenhardt.
In 1992 and 1998 the melting and processing capacity was replaced, extended and brought into line with the latest state of the art technology.
 | Alusad ALUSAD from Metalltechnik Schmidt is a bright aluminium granulate of spherical shape which is free from slag inclusions. Degassed and refined in a controlled melting operation. Optimum hardness and a long working life are achieved by a tight analytical regime.
ALUSAD cleans, compacts and levels the surfaces of aluminium workpieces.
ALUSAD prevents subsequent corrision of the blasted surfaces.
ALUSAD minimises wear on your blasting installation like no other blasting shot.
You have a choice of pellet size, depending on the type and size of the component, its wall thickness and the required surface finish, or the intended surface appearance: |  | Chilled cast blasting grit Chilled iron media alloyed with Titanium. A rougher abrasive based on alloyed cast iron, not to be confused with the usual, brittle chilled cast blasting grit. The addition of titanium provides the chilled cast grit with a special strength, giving it a better working life and performance.
Characteristics: angular, crack resistant with lower wear because of the compact granules, less dust development during blasting, the least possible wear-and-tear to the installation, low consumption. The surface roughness and condition make it ideal for the following coatings. |  | FERROSAD low-carbon, cast-steel blasting shot FERROSAD low carbon, cast-steel blasting shot is longer lasting and more durable than high-carbon blasting shot because it is resistant to cracking. Low-carbon blasting shot is produced from high-grade, low residual low-carbon scrap.
Consequently, it exhibits a bainitic microstructure, which is both resistant and durable, following the comminution process (isothermal transformation). Tests carried out by customers showed reductions of more than 20% in consumption when compared with high-carbon blasting shot, resulting from the special characteristics of the FERROSAD material. |  | Steel grit for blasting Steel grit is produced by crushing material that has a similar chemical composition to that of high-carbon steel shot. With its broken, sharp edges, steel grit is more abrasive than round shot. In spite of the increased wear-and-tear to the installation resulting from this abrasiveness, it is nonetheless necessary for certain blasting operations, e.g. roll etching or in surface preparation for the metal spraying. | |
