Ding Testing & Inspection: Pitting Corrosion Evaluation, Safeguarding the Microscopic Defense of Materials
In the industrial sector, the use of metallic materials is ubiquitous, but they may suffer from pitting corrosion in specific environments. This is a localized and accelerated corrosion process that often develops rapidly under the radar, ultimately leading to material failure. Ding Testing & Inspection's pitting corrosion evaluation service aims to assess the pitting corrosion resistance of metallic materials through professional testing techniques, ensuring their long-term stable operation.
Service Introduction
Since 2023, Ding Testing & Inspection (DTI) has accepted over 500 batches of material inspections and corrosion tests witnessed on-site by internationally renowned inspection agencies each year. Our services are supervised by well-known inspection agencies, recognized by internationally leading users, and endorsed by top-tier manufacturers and engineering firms in the industry!
Pitting corrosion evaluation generally involves assessing samples that have already experienced pitting corrosion, including the degree of corrosion, weight loss, surface location, size, shape, density, uniformity of distribution, depth (average and maximum depth) of pits, and the relative position of pits to microstructure, surfaces, edges, and crevices.
Ding Testing & Inspection's pitting corrosion evaluation service employs internationally recognized testing methods and standards to comprehensively assess the pitting corrosion resistance of metallic materials in various media. Our services include, but are not limited to, laboratory accelerated testing, on-site corrosion monitoring, material selection consultation, and corrosion prevention recommendations. Through precise data analysis and professional technical interpretation, we provide scientific corrosion prevention solutions for our clients.
Industry Pain Points
The occurrence of pitting corrosion is often closely related to the chemical composition, microstructure, and usage environment of the material. Without professional evaluation, the risk of pitting corrosion is difficult to predict and manage. Once it occurs, it may lead to premature equipment replacement, reduced production efficiency, and even safety accidents.
Application Fields
Ding Testing & Inspection's service scope is extensive, covering pitting corrosion evaluation, including but not limited to:
-
Assessment of pitting corrosion sensitivity in stainless steel, aluminum alloys, copper alloys, and other metallic materials
