Product Introduction
Detection range
Applicable materials: Suitable for various nickel based alloys such as nickel chromium molybdenum corrosion-resistant alloys, nickel copper alloys, nickel chromium iron high-temperature alloys, etc., covering typical grades such as Hastelloy, Inconel, Monel, etc.
Applicable objects: including nickel based alloy plates, rods, pipes, forgings, welded joints, equipment cylinders, pipelines, flanges, and various high-temperature corrosion-resistant service components.
Applicable scenarios: Suitable for testing the intergranular corrosion sensitivity and quality assessment of nickel based alloys after welding, solution treatment, sensitization treatment, and long-term high-temperature service.
Test Item
Sensitivity assessment of intergranular corrosion: Evaluating whether nickel based alloys undergo intergranular corrosion in corrosive media.
Corrosion morphology detection: Macroscopic observation of corrosion state, microscopic inspection of grain boundary corrosion depth and expansion degree.
Bending test detection: Conduct a bending test after corrosion to check for intergranular corrosion cracking on the surface.
Corrosion weight loss test: Determine the weight change of the sample before and after corrosion to assist in evaluating the degree of corrosion.
Special testing of welded joints: detecting the intergranular corrosion tendency of welds and heat affected zones.
