Ding Testing & Inspection: Pitting Corrosion Testing, Precise Assessment of Material Corrosion Resistance

In industrial applications, corrosion of metallic materials has always been one of the main causes of equipment failure and production interruptions. Pitting corrosion, as a form of localized corrosion, forms small pits on the metal surface that rapidly penetrate the material, causing irreversible damage. Ding Testing & Inspection's pitting corrosion testing service focuses on assessing and preventing this potential corrosion risk to ensure the long-term stability and safety of materials.

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 testing, also known as pitting corrosion, is a form of localized corrosion where corrosion is concentrated in small areas on the metal surface and penetrates deeply into the metal, potentially causing perforation.

Ding Testing & Inspection's pitting corrosion testing service employs a range of standardized testing methods, such as ASTM G48 "Stanard Test Methods for Pitting and Crevice Corrosion Resistance of Stainless Steels and Related Alloys Using Ferric Chloride Solution," to comprehensively assess the pitting corrosion resistance of materials in specific environments. Our services include not only laboratory testing but also on-site corrosion monitoring, material selection consultation, and corrosion prevention scheme design, helping clients control corrosion risks at the source.

Industry Pain Points

Pitting corrosion typically occurs in passivating metals or alloys and often happens under conditions where aggressive anions and oxidizers coexist, such as in stainless steel, titanium, and titanium alloys. In nearly neutral chloride-containing aqueous solutions or other specific media, localized dissolution can occur, forming pitting corrosion. When metals are under stress, pitting corrosion can easily become the source of stress corrosion cracking or fatigue corrosion.

The occurrence of pitting corrosion is often hidden and difficult to detect initially, but once formed, it develops rapidly and can be destructive to the material. This not only increases maintenance costs but can also lead to safety accidents, severely affecting the operation and reputation of enterprises.
