What Grades of Casting Do We Manufacture?
At Castwise, a premier ductile iron manufacturer and cast iron foundry in India, we specialize in producing a wide range of high-quality castings. With extensive experience in green sand molding, we cater to various industrial needs, offering machined castings that meet international standards. Here’s an overview of the casting grades we manufacture:
Grey Cast Iron: Castwise produces several grades of grey cast iron, adhering to established standards. Our common grades include:
- FG25 (EN-GJL-250): Known for its good machinability and wear resistance, suitable for applications requiring moderate strength.
- FG30 (EN-GJL-300): Offers higher strength and hardness, making it ideal for heavy-duty applications.
We also cater to specific customer requirements for other grades such as:
- FG20 (EN-GJL-200): Lower strength but excellent vibration damping properties.
- FG35 (EN-GJL-350): Provides higher strength and hardness for specialized applications.
Ductile Iron (Nodular Iron): As a leading ductile iron manufacturer, we produce various grades of ductile iron, known for their excellent mechanical properties, including high strength, ductility, and impact resistance. Our expertise allows us to deliver castings that meet precise specifications, ensuring high performance and reliability. The grades we manufacture include:
- 600/3 (EN-GJS-600-3): High strength and ductility.
- 500/7 (EN-GJS-500-7): Balanced strength and ductility.
- 450/12 (EN-GJS-450-12): Excellent elongation properties.
- 400/18 (EN-GJS-400-18): Offers outstanding ductility, and we can provide annealing to enhance its properties.
- 550/6 (EN-GJS-550-6): High strength with good ductility.
- 700/2 (EN-GJS-700-2): Exceptional strength, a grade not commonly produced by many foundries.
Case Study: Gauge Wheel Arm: A customer from the USA required the 600/3 (EN-GJS-600-3) grade for their gauge wheel arm component. The standard hardness range for this grade is 180-270 BHN, but the customer needed a harder range of 250-280 BHN without heat treatment. Despite the challenge, our team at Castwise achieved this precise range, meeting the customer's stringent requirements. This close range was achieved through meticulous control of the casting process and raw materials. We continue to supply this component in good numbers, maintaining zero metallurgical rejections.
Austempered Ductile Iron (ADI): At Castwise, we have been manufacturing ADI grades for the past five years, producing all grades from 1 to 5 as per ASTM standards. Our most commonly produced grade is:
- Grade 1 (ASTM A897/897M): Known for high strength and toughness. We successfully converted an investment casting steel product into ADI Grade 1 for the RV industry, creating a bar pivot for towing hitches. This project was delivered in good numbers with no complaints.
- Grade 2 (ASTM A897/897M): Our latest development is for a Russian customer in the bearings sector, supplying to railways operating in sub-zero conditions.
- Grade 3 (ASTM A897/897M): Combines good strength and toughness, used for components requiring a balance of these properties.
- Grade 4 (ASTM A897/897M): Known for higher strength and wear resistance, suitable for parts exposed to heavy loads and abrasion.
- Grade 5 (ASTM A897/897M): Required for high hardness and work hardenability, typically used in wear products. We have successfully achieved hardness levels of 480+ BHN in mass production.
Machining Capabilities: Beyond casting, Castwise excels in providing machined castings through advanced CNC machining. Our facility ensures that every casting meets stringent quality standards, offering precision and accuracy for complex components.
Quality and Export Expertise: We take pride in delivering quality castings from India to customers worldwide. As an exporter of machined castings, we adhere to rigorous quality control measures, ensuring our products meet international standards and customer expectations.
