Kohlenstoffstahlguss

With excellent mechanical properties, carbon steel castings are more cost-effective than stainless steel castings, offering a perfect balance of performance and affordability. The carbon content is a key factor in determining the toughness of steel. After heat treatment, higher carbon content makes the steel stronger and more wear-resistant, making it the preferred choice for demanding industries such as construction, mining, and heavy machinery.
As an experienced carbon steel casting manufacturer, we specialize in producing high-quality carbon steel castings with superior strength, toughness, and wear resistance. Our advanced production processes and rigorous quality control ensure that each casting meets industry standards and delivers outstanding performance. Whether for industrial equipment, automotive components, or structural applications, our carbon steel castings provide reliable and durable solutions tailored to meet the needs of our clients.

Available Carbon Steel Casting Processes

Carbon Steel Investment Casting
Carbon steel investment casting uses the traditional lost wax casting process to produce carbon steel components. In recent years, we have undertaken extensive upgrades, incorporating advanced silica sol shell-making technology. Additionally, we have introduced an innovative process that combines coated sand with shell-making, optimizing production time and improving surface finish. Common carbon steel investment casting parts include railway components and automotive parts.
Carbon Steel Sand Casting
Carbon steel castings produced using the sand casting process are known as carbon steel sand castings. In this process, different foundries select various sand materials based on performance requirements, such as silica sand, resin sand, ceramic sand, and expandable sand. We primarily use resin sand and ceramic sand, both known for their uniform granularity and excellent refractory properties, making them ideal for high-temperature, high-performance casting applications.
Carbon Steel Shell Casting
Carbon steel shell casting is an advanced shell molding process used to produce high-quality carbon steel components. Our fully automated production line ensures efficiency and consistent quality, with a monthly capacity of 800 tons and the ability to manufacture castings weighing up to 200 kg. This process delivers precise dimensions, excellent surface finishes, and intricate designs, making it ideal for industries such as automotive, construction, and heavy machinery. We provide durable, reliable, and cost-effective carbon steel shell castings tailored to meet the diverse needs of our clients.

Carbon Steel Casting Cleaning
Carbon steel investment casting, also known as lost wax casting, is a precision casting process that uses wax patterns to create high-accuracy, intricate shapes. This method provides excellent surface finish, tight tolerances, and minimal post-processing, making it ideal for complex components in automotive, aerospace, and industrial machinery. After casting, thorough cleaning is essential to remove any residual mold materials, scale, or impurities. Our cleaning process ensures that each carbon steel casting meets the highest standards of quality and readiness for further treatment or assembly.
Carbon Steel Casting Machining
Our machining facility houses over 30 CNC machines, providing exceptional flexibility for machining carbon steel castings according to customer drawings. Our skilled technicians, with years of experience, ensure high precision and efficiency in every operation. By maintaining in-house machining capabilities, we reduce the complexity of working with multiple suppliers and minimize lead times. Whether it’s turning, milling, drilling, or grinding, we deliver carbon steel castings with exact specifications and superior surface finishes, ready for immediate use.
Carbon Steel Casting Inspection
Quality assurance is a critical part of our process. We employ various inspection methods, including dimensional checks using CMM (Coordinate Measuring Machine), visual inspections, and non-destructive testing (NDT) techniques like ultrasonic and magnetic particle testing. These methods ensure that every carbon steel casting meets the required specifications and performance standards. Additionally, we apply surface treatments such as rust-proof oil coating, painting, sandblasting, chemical treatment, anodizing, and electrophoresis to achieve corrosion resistance, enhance wear resistance, and improve appearance. Our rigorous inspection and treatment processes guarantee that our carbon steel castings deliver reliability and durability in even the most demanding applications.
Anpassbare Oberflächenbehandlungsoptionen
Kugelstrahlen
Kugelstrahlen ist ein Oberflächenbehandlungsverfahren, bei dem abrasive Materialien mit hoher Geschwindigkeit geschleudert werden, um Oberflächenverunreinigungen, Zunder oder Rost zu entfernen. Dieses Verfahren verbessert die Oberflächenhaftung für nachfolgende Beschichtungen und erhöht die Ermüdungsbeständigkeit.
Bearbeitung
Die spanende Fertigung ist ein Präzisionsverfahren, das zur Erzielung enger Toleranzen und glatter Oberflächen eingesetzt wird. Es umfasst Fräsen, Drehen, Bohren und Schleifen, um spezifische Maß- und Funktionsanforderungen zu erfüllen.
Lackierung
Eine Lackbeschichtung verleiht legierten Stahloberflächen ein schützendes und dekoratives Finish. Sie erhöht die Korrosionsbeständigkeit und ermöglicht verschiedene Farb- und Strukturoptionen. Dadurch eignet sie sich ideal für ästhetische und funktionale Zwecke.
Pulverbeschichtung
Pulverbeschichtung ist ein Trockenveredelungsverfahren, das eine langlebige, verschleißfeste und korrosionsbeständige Oberfläche erzeugt. Sie bietet ein einheitliches Erscheinungsbild und ist in verschiedenen Farben und Texturen erhältlich.
Verzinkte Beschichtung
Beim Galvanisieren wird eine Zinkschicht auf die Stahloberfläche aufgetragen, die einen hervorragenden Korrosionsschutz bietet. Feuerverzinken und galvanisches Verzinken sind gängige Verfahren, um die Lebensdauer von Stahlbauteilen zu verlängern.
Schwarze Oxidbeschichtung
Die Schwarzoxidbehandlung erzeugt eine dünne, schwarze Schutzschicht auf der Stahloberfläche, die die Korrosionsbeständigkeit verbessert und die Lichtreflexion reduziert. Sie wird häufig in der Automobil-, Luft- und Raumfahrt- und Werkzeugindustrie eingesetzt.
