Frequently Asked Questions

Why is Inconel more expensive than stainless steel?

Inconel contains expensive nickel (50-70%) and other alloying elements like molybdenum and niobium. Its superior high-temperature properties, corrosion resistance, and difficult machining characteristics contribute to higher material and fabrication costs. However, its extended service life in extreme environments provides excellent long-term value.

Which Inconel grade should I choose for my application?

Grade selection depends on operating temperature, corrosive environment, and strength requirements. Inconel 600 suits general high-temperature applications, 625 excels in marine and chemical environments, 718 offers maximum strength for aerospace applications, and X-750 provides excellent spring properties. Our engineers can recommend the optimal grade for your specific needs.

What thicknesses of Inconel sheet can you fabricate?

We work with Inconel sheets ranging from 0.5mm to 10mm thickness. Our specialized equipment handles the material’s work-hardening characteristics across all gauges. For applications requiring thicker material, we can source and fabricate plate stock up to 25mm thickness.

Do you provide material certifications?

Yes, we provide complete material traceability documentation including mill certificates, chemical composition reports, mechanical property test results, and heat treatment certifications. All Inconel material meets ASTM and ASME specifications with full compliance documentation.

Can you weld Inconel to other materials?

Inconel can be welded to certain stainless steels and other nickel alloys using proper filler materials and techniques. Dissimilar metal welding requires careful consideration of thermal expansion differences, galvanic corrosion potential, and operating conditions. Our certified welders have expertise in complex dissimilar metal joints.

What are typical lead times for Inconel fabrication?

Lead times depend on material availability, part complexity, and heat treatment requirements. We provide detailed timelines during the quoting process and maintain transparent communication throughout fabrication. Our experienced planning ensures efficient project execution while maintaining the highest quality standards.
