Simulation
Computer-aided filling and solidification simulation supports the development of casting-oriented component designs at an early stage. This allows Pleissner Guss to review mould filling, solidification behaviour and potential production risks before casting begins. As a result, prototypes and series components can be developed more efficiently, with improved casting quality and optimized production processes.

Industries & Applications
Our castings serve a broad spread of demanding sectors, ranging from valves and turbines to shipbuilding, rail and defence. The examples below show typical applications, materials and representative component weights.
Valves & Pumps
Industrial valves and pumps operating in demanding process environments rely on cast components in unalloyed, martensitic, duplex and super duplex grades, a combination of corrosion resistance, weldability and dependable mechanical performance.
Reference example: suction casing in G20Mn5 QT, 600 kg.
Energy & Turbomachinery
Steam turbines, gas turbines and hydropower systems call for castings that hold up under both high and low service temperatures. For advanced high-temperature applications, we process COST grades developed for increased creep resistance.
Reference example: steam turbine housing in G17CrMoV5-10 (upper part 2,800 kg, lower part 2,400 kg).
Oil & Gas
For the oil and gas industry we cast high-pressure valve and fitting bodies in duplex, super duplex and nickel-based grades. These materials pair strong pitting-corrosion resistance with high mechanical strength for offshore and sour-service conditions.
LNG & Compressor Technology
LNG compressors and compressor systems use austenitic nodular cast iron (EN-GJSA-XNi35), which brings together excellent low-temperature toughness and high corrosion resistance for cryogenic service.
We also supply block and round castings as preforms (ingots) for downstream forging, ring-rolling and electroslag remelting (ESR).
Mechanical & Plant Engineering
Support frames, structural castings and process equipment for mechanical and special-purpose machinery are produced to customer specification, supplied either as-cast or fully machined and ready to install.
Reference example: CNC-machined support frame in G20Mn5 QT, 4,000 kg.
Shipbuilding, Offshore & Chemical Industry
Marine environments and chemically aggressive processes demand corrosion-resistant castings in duplex, super duplex and nickel-based alloys. These applications are backed by manufacturer approvals from leading classification societies for shipbuilding and offshore technology, as well as approvals for pressure vessel components. All standard testing requirements are fulfilled in-house by qualified personnel according to ASNT and EN standards.
Railway Industry
Safety-relevant cast components for railway vehicles are covered by a complete in-house testing chain, including surface crack, ultrasonic and radiographic testing plus dimensional inspection, meeting the demanding quality and documentation requirements of the railway industry.
Further Areas of Application
Further areas of application include wind energy and defence technology, where robust cast components are required for demanding industrial and safety-relevant systems

Frequently Asked Questions
What are steel castings?
Steel castings are components manufactured by pouring molten steel into sand moulds. This manufacturing process enables the production of complex geometries that are difficult or uneconomical to achieve with forged or welded components.
Compared with cast iron, steel castings offer higher toughness, excellent weldability and high mechanical strength, making them suitable for demanding applications in energy technology, valves, pumps and mechanical engineering.
What is the difference between steel castings and cast iron?
Steel castings contain less than 2% carbon and are characterized by high strength, ductility and weldability. Cast iron has a higher carbon content and offers excellent vibration damping but is generally not weldable.
Pleissner Guss manufactures both steel castings in a wide range of alloy grades and austenitic nodular cast iron (Ni-Resist) according to EN 13835 and ASTM A 469.
Which steel casting standards does Pleissner Guss manufacture?
Pleissner Guss produces steel castings in accordance with EN 10213, EN 10293, EN 10340 and EN 10283, as well as ASTM A 216, ASTM A 217, ASTM A 351, ASTM A 352, ASTM A 487, ASTM A 743, ASTM A 744 and ASTM A 890/995.
Nickel-based alloy castings are manufactured according to ASTM A 494. Equivalent materials and customer-specific grades are available on request.
Can Pleissner Guss manufacture prototype steel castings?
Yes. Computer-aided filling and solidification simulation allows component geometry and casting processes to be optimized before production begins. This enables the efficient manufacture of prototypes and single components while reducing development time.
In which delivery condition are steel castings supplied?
Steel castings can be supplied as-cast after heat treatment and testing or as fully machined, ready-to-install components. Our in-house capabilities include CNC machining, production welding and construction welding.
What is casting-oriented design?
Casting-oriented design optimizes component geometry and wall thicknesses to support reliable mould filling and solidification while minimizing the risk of shrinkage cavities, cracks and residual stresses.
Pleissner Guss uses modern simulation software to optimize component design during the planning phase.
Is Pleissner Guss ISO certified?
Yes. Pleissner Guss is certified according to:
ISO 9001:2015 – Quality Management
ISO 14001:2015 – Environmental Management
ISO 50001:2018 – Energy Management
All certifications have been issued by DNV Business Assurance.
In addition, Pleissner Guss holds manufacturer approvals for pressure vessel components, nuclear technology, railway applications, shipbuilding and offshore technology.
Does Pleissner Guss manufacture sustainable steel castings?
As part of GMH Gruppe, Pleissner Guss produces steel from recycled scrap in electric arc furnaces. Across GMH Gruppe’s electric-arc sites this cuts CO₂ emissions by a factor of five compared with conventional blast-furnace production, supporting a circular-economy approach and a lower CO₂ footprint for our customers.
