SEMI-FINISHED PRODUCTS: A NOTCH ABOVE
Zapp provides consistent product quality for smooth production at your site.
Corrosion and high-temperature resistance are the two essential requirements for materials in the chemical process industry.
You can choose between our stainless steels, Ni-Mo, Ni-Cr, and Ni-Cu alloys, as well as high-temperature materials – directly from stock or according to your specifications.
We supply you with reliable sheets and plates for your containers and equipment. Thanks to our large service center in Schwerte, we can often send your material within 24 hours.
A large selection of nickel alloy materials is available to you. We are also happy to supply you with the right welding filler metal. This saves you time and effort.
Our material is provided with the most important specifications according to ASTM, NACE, and DIN.
Test reports acc. to EN 10204 / 3.1 are available for all semi-finished products.
Rupture disks
Nickel-based alloys are suitable for rupture disks for pressure protection in chemical plants. You can get our sheets and strips from production or from stock as required. We ensure the highest quality with demanding specifications.
You will receive a factory certificate according to EN 10204 / 3.1 for all materials.
Seals
We supply thin sheet and strip for metallic seals in chemical plants.
Our materials are available on short delivery times
Alloy C-4, C-22, C-276,
Alloy 201, 400, 600, K-500, 625, X750, 718,
austenitic materials 1.4301, 1.4404, 1.4310
more on request
They are available from a thickness of 0.025 mm. Secure short delivery times from our strip and sheet metal warehouses in Unna and Schwerte. Our production also offers individual solutions.
Expansion joints
We have thin strips and sheet made of nickel alloys for expansion joints. In the chemical process industry, we supply semi-finished products according to specification from a thickness of 0.01 inch.
Alloy C-4, Alloy C-22, Alloy C-276
Alloy 201, Alloy 400, Alloy K-500
Alloy 625/ 625LCF
Titanium Grade 2
We are happy to offer further testing services such as tensile tests or ultrasonic tests. Alternatively, the material can also be shipped to an external testing company. You decide! We deliver strip from our own production or from stock as required.
Solenoid valves
Reliably switching (solenoid) valves are essential for the control of fluids in chemical process engineering. The stainless steel 1.4105 is an example of this reliability. This and other materials are used in corrosive media. With their excellent magnetic properties, they support the design of small and energy saving valves such as micro valves.
You can also get bars made of nickel-based alloys for light and heavy valve series at short notice from stock in Germany. You get multi-specified semi-finished products according to ASTM, NACE, or DIN in diameters from 0.236 – 15.748 inch.
Many common materials such as Alloy 59, 201, 400, K-500, 625, 718, C-4, C-22, C-276, C-2000 are among them. We are happy to make TÜV approvals or upgrades possible.
Whether as a bar for shafts or sheets for housings, we supply all nickel and titanium materials in accordance with the international standards ASTM, NACE, or DIN. The world's leading pump manufacturers trust our materials for their most demanding applications.
Agitators
Bars and sheets for the production of industrial agitators are one of our core applications. We have a large selection of nickel alloys in our service center.
In sheet thicknesses from 0.02 to 1.97 inch and bar diameters from 0.236 to 15.748 inch, we maintain a stock for your needs, among other things:
Alloy C-4 (2.4610)
Alloy C-22 (2.4602)
Alloy C-276 (2.4819)
Alloy 625 (2.4658) or
Pure Titanium Grade 2 (3.7035)
Forged semi-finished products
Our area of expertise is finished forged semi-finished products in nickel and titanium alloys according to your drawing and individual specification. We are happy to advise you on the selection.
They are available as:
bars, rings, disks
drawing parts
Approvals by external test companies are possible in the materials 2.4600, 2.4602, 2.4605, 2.4610, 2.4668, 2.4856, 3.7035, and 3.7164. We also deliver within 24 hours.
Connecting parts
Temperature resistance and high tensile strength are extremely important here, because connecting parts are often used in the most demanding environments. We would be happy to support you with our bars made of nickel and titanium alloys.
All materials are available in dimensions between 0.236 – 15.748 inch.
