Technical Questions
Frequently Asked Questions
What is the difference between Inconel 625 and Inconel 718?
Alloy 625 is typically selected for outstanding corrosion resistance and weldability, while Alloy 718 is precipitation hardened and commonly chosen where higher mechanical strength and fatigue performance are required.
Which alloy is best for seawater?
Inconel 625 and Monel 400 are common candidates for marine service. The correct choice depends on temperature, flow conditions, galvanic compatibility, strength and the specific seawater exposure.
Can you manufacture custom fasteners?
Yes. AODSON manufactures drawing-specific bolts, screws, studs, nuts, washers and special fasteners in nickel-based alloys.
Do you provide material certificates?
Yes. Material certificates, heat traceability and additional inspection documentation can be supplied according to the order requirements.
What standards do you support?
We support common ASTM, ASME, DIN, ISO and customer-specific requirements, subject to material, size and manufacturing route.
Can you manufacture according to drawings?
Yes. Send the drawing, alloy specification, quantity and required documentation so our engineering team can review manufacturability and propose the production route.
