Stainless Steel Metal Investment Casting and Foundry Services Metal Casting

As a specialized manufacturer in precision metal components, we provide comprehensive stainless steel investment casting and foundry services that deliver exceptional dimensional accuracy, superior surface finish, and reliable performance. Our metal casting expertise combines advanced investment casting technology with rigorous quality control to produce complex stainless steel components for demanding applications across various industries.

Material Excellence and Performance Characteristics

We work with a comprehensive range of stainless steel alloys to meet diverse application requirements:

300 Series Austenitic Stainless Steels
Our 304 and 316 stainless steels offer excellent corrosion resistance and good mechanical properties across a wide temperature range. 304 stainless steel provides tensile strength of 515 MPa minimum with outstanding formability and weldability. 316 stainless steel, enhanced with 2-3% molybdenum, delivers superior resistance to chlorides and acidic environments, making it ideal for marine and chemical processing applications.

400 Series Martensitic Stainless Steels
We utilize 410 and 420 stainless steels for applications requiring higher strength and wear resistance. These alloys can be heat treated to achieve tensile strength up to 1650 MPa while maintaining good corrosion resistance. 420 stainless steel, with its higher carbon content (0.15-0.40%), provides enhanced hardness and wear characteristics after heat treatment.

Precipitation-Hardening Grades
For critical applications demanding high strength-to-weight ratios, we offer 17-4PH stainless steel, which can be heat treated to achieve tensile strength of 1310 MPa while maintaining good corrosion resistance and dimensional stability.

Advanced Investment Casting Process

Our manufacturing methodology employs sophisticated investment casting technology:

Precision Pattern Development
We create intricate wax patterns using aluminum injection molds designed with precise shrinkage allowances. Each pattern undergoes meticulous inspection to ensure dimensional conformity before ceramic shell building.

Ceramic Shell Engineering
Multi-layer ceramic shell construction creates robust molds capable of withstanding high pouring temperatures. Our proprietary shell formulation ensures:

• Superior surface finish quality (Ra 3.2 μm or better)

• Tight dimensional tolerances (±0.13 mm per 25 mm)

• Accurate reproduction of complex geometries

• Minimal inclusion defects

Controlled Casting Operations
Our vacuum-assisted pouring and solidification control ensures metallurgical integrity:

• Computerized melting temperature control

• Protective atmosphere pouring

• Directional solidification optimization

• Strategic gating and risering design

Quality Assurance and Certification

We maintain rigorous quality control throughout our manufacturing process:

• Spectrochemical analysis for precise chemical composition control

• X-ray inspection for internal integrity assessment

• Liquid penetrant testing for surface defect detection

• Mechanical property testing to confirm performance specifications

• Compliance with international quality standards including ISO 9001
