Nickel and alloys - Import export

CuNi3Si alloy with very good bendability, very good hot and cold forming properties, a high strength and a good corrosion resistance. Perfect material for Connectors, bent parts, relays.

Engineered for : • Stainless steel • Heat resistant steels • Cold and hot working steels • Hardened steel up to 1900 N/mm2 • Nickel based alloys • Aluminium-silicon alloys • Copper-nickel alloys • Titanium and titanium alloys • Exotic, hard to cut alloys

Engineered for : • hard and tough materials up to 1700 N/mm2 tensile strength • Stainless steel • heat resistant duplex steel • nickel based alloys • aluminium alloys • titanium bades alloys

Solid wire electrode suitable for joining and surfacing alloys of similar composition with up to 30% nickel as well as non-ferrous alloys and dissimilar steel grades. The deposit weld metal is highly resistant to seawater, typical applications include usage in shipbuilding, oil refineries, food processing industry, the engineering of general corrosion proof vessels and equipment.

Our open-die forging presses play an important part among the forming presses. Siempelkamp supplies complete open-die forging presses equipped with manipulators and ancillary equipment such as lifting turntables and quite a number of additional components. Our presses operate reliably, fast and precisely, operating at pressing forces between 10 and 160 MN. The range of presses available comprise push-down or pull-down designs, two- or fourcolumn designs with oil-hydraulic or water-hydraulic drives. High-stroke frequency contributes to the eciency of these presses. Our customers produce bars, discs, rings, and anges from materials such as steel, high-alloy steel, nickel-based alloys, titanium, and aluminium on these presses. They prefer to order turn-key plants including integrated manipulators, turntable, die magazine, and die-changing system.

With the ring rolling mill Siempelkamp completes its range of products for the manufacture of rings. From forging the pre-forms to manufacturing the ring blanks to ring rolling, we supply everything from a single source. Siempelkamp’s ring rolling mill manufactures seamless rings made of steel and special materials such as nickel-base, titanium, or aluminium alloys using maximum radial and axial pressing forces. The radial pressing force is hydraulically generated and applied to the part via a mandrel roll. Radial rolling is carried out by reducing the roll gap between the driven external roller and the mandrel roll. The axial pressing force is also hydraulically generated and applied to the part via the upper axial roller. Axial rolling is carried out by means of the vertical forward feed of the upper axial roller. A centring device provides for the correct position of the ring during the rolling process.
