We manufacture screws, customised bolts, special screws, fasteners, CNC precision turned parts, CNC precision milled parts as well as standard parts from a variety of materials and special materials in all grades. In order to offer short delivery times, we maintain an extensive input material stock.
These stainless austenitic steels are characterized by high strength and corrosion resistance also against salt water and are on account of the alloying with manganese or molybdenum not magnetizable. Non-magnetizable steel is also referred to as a submarine-steel. Typical material numbers are
Heat resistant steels
Heat-resistant ferritic steel is thermically highly resilient and retains its good strength properties on account of the alloying with chromium, silicon and aluminium under the action of hot gases and combustion products. Typical material numbers are
Rust and acid resistant steels
Referred to as rust-and acid-resistant, are chromium-nickel-steels that are due to their high strength and corrosion resistance counted as one of the most important fasteners made out of stainless steel. Typical material numbers are
Very high heat resistant steels
Very high heat resistant steel is specially alloyed and distinguished by the fact that even at high temperatures; its material properties (strength, elasticity) are largely maintained. Typical material numbers are
Engineering steel is used where higher strength is required (e.g. chromium-molybdenum steel) and / or to replace steel grades that are to be protected from corrosion through galvanic protection, zinc coating or painting. Typical material numbers are
Non-ferrous metals refer to metals that do not entail iron as a main element. Common representatives are, for example, copper alloys, aluminium alloys or magnesium alloys. Typical material numbers are
Typical of many special materials is the extremely high resistance to specific challenges. Their operating temperatures are often higher than that of steel. Accordingly challenging is the processing of these super alloys that requires extensive know-how and adapted CNC technology.
Examples of special materials
Hastelloy is the brand name of high-resistance alloys with high nickel content. Depending on the alloy, the material is optimized in the direction of heat resistance or corrosion resistance.
Incoloy is the brand name of special nickel-iron-chromium alloys that are in particular used in the chemical and petrochemical process technology.
Inconel is a brand name of corrosion-resistant nickel-based alloys, which are suitable for applications in extreme environments.
Monel is a brand name of nickel-copper alloys with high strength and excellent corrosion resistance, as compared to sea water, hydrofluoric acid, or sulphuric acid.
Nimonic is a brand name of high tensile strength nickel-chromium alloys with high corrosion and oxidation resistance. Typical material numbers of special materials are
Titanium is characterized through low weight by high strength and corrosion resistance.
