Is the flange forged or cast？
Characteristics of Forged Flanges
1. Superior mechanical properties
Forged flanges eliminate the defects of steel ingots (such as segregation and porosity) by hamming the tube billets. They have a dense structure and good streamlined shape, and possess higher strength, pressure resistance and temperature resistance, making them particularly suitable for high-pressure and high-temperature environments. Its carbon content is usually low and it is not prone to rust.
2. The production process is complex
It needs to go through processes such as cutting, heating and forging (free forging/die forging), which is relatively costly, but it can avoid common defects in casting such as pores and cracks. Die forgings have higher precision and are suitable for mass production.
3. Main materials and standards
Commonly used materials include carbon steel, alloy steel and stainless steel, which comply with various standards such as national standards and American standards. Anti-corrosion treatments include oiling and galvanizing.
Characteristics of Cast Flanges
1. Cost and efficiency advantage
The casting flange blanks have precise dimensions, small processing volume and low production cost, making them suitable for mass production. However, there may be defects such as pores and inclusions, and the internal structure has a poor streamlined shape.
2. Application scenarios
It is mostly used in medium and low pressure environments with low strength requirements, such as ordinary pipe connections. Centrifugal cast flanges have higher quality and finer structure.
All of our precision custom investment cast parts are made according to customer's design, our work flow chart is as belows:
Excellent material properties: CF8M stainless steel castings
Corrosion Resistance : CF8M (similar to 316L stainless steel) performs exceptionally well in harsh environments (chemical, Marine, pharmaceutical), resisting chloride ion corrosion and acidic media, and extending the lifespan of parts.
High strength and high temperature resistance : Suitable for high-temperature and high-pressure scenarios (such as valves and pump bodies), reducing the risk of deformation and failure.
Customized Casting : Investment casting technology enables complex geometric shapes, thin-walled structures and fine details, reducing subsequent processing costs.
CNC Precision Machining: Precise matching of strict requirements
Micron-level accuracy : Ensure dimensional consistency of complex parts (such as medical devices, aviation components) and reduce assembly errors.
Flexible Production: Supports small-batch customization to large-batch delivery, and flexibly responds to design changes and urgent orders.
Quality Control System: Full-process SPC monitoring, three-dimensional detection and material batch traceability to ensure compliance with standards such as AS9100 and ISO 9001.
Cost Reduction and Efficiency improvement: Reduce the demand for secondary processing, optimize the utilization rate of raw materials, and shorten the supply chain cycle of customers.
One-stop solution: Time-saving, labor-saving and cost-saving
End-to-end service : The entire process from casting, machining to surface treatment is independently completed, avoiding the risk of multi-supplier collaboration.
Rapid Response: The technical team provides DFM (Design for Manufacturability) optimization suggestions to shorten the product development cycle.
Industry-recognized and reliable cooperation
Complete certifications : Certifications such as ISO 9001, AS9100, etc., ensure that the products comply with international standards.
After-sales Guarantee : Provide quality commitment, technical support and rapid after-sales response, and establish long-term partnerships.
When you choose our company's products, you will obtain:
✅ Longer service life (Double guarantee of materials and workmanship)
✅ Lower combined cost (reduced maintenance, replacement and downtime losses)
✅ Higher compliance (to meet multi-industry certification and audit requirements)
✅ Stronger competitiveness (improve word-of-mouth in the end market with high precision and reliable products)
1Q: Why choose CF8M stainless steel for investment cast parts?
1A: CF8M (similar to 316L stainless steel) offers exceptional corrosion resistance in harsh environments, high-temperature stability, and compliance with strict industry standards. It’s ideal for applications requiring durability and hygiene, such as medical devices or marine components.
