TCR Engineering in Mumbai supplies high carbon steel based corrosion coupons

TCR Engineering supplies corrosion coupons of various sizes and specifications. Recently for a customer in Nigeria, TCR Engineering has created corrosion coupons based on high carbon steel with carbon in the range of 0.8 to 1.1%.
TCR Engineering created coupons of the size 70 x 30 x 3mm with a 6mm hole at centre of top edge of 30mm side; with centre of hole at 8mm below the surface.

TCR now detects and estimates of High Temperature Hydrogen Attack (HTHA) by Advanced Backscatter Ultrasonic Testing

TCR has designed a procedure based on API 941 for detection and estimation of HTHA by ABUT
High temperature hydrogen attack (HTHA) is observed in steels exposed to high temperature above 200 deg. C. At high temperature atomic hydrogen diffuses in steel. This hydrogen reacts with Carbon of steel and forms CH4. This bubble’s at grain boundary and forms voids at grain boundary.
MC + 4H = M + CH4. These bubbles exert pressure and also coalesce resulting in to fissures. The growth of voids and fissures weakens the metal and the fissures develop in to major crack. This reaction decarburizes the steel, produces micro cracks/fissures and lowers toughness of steel but not necessarily cause loss in thickness. The degree of hydrogen attack depends upon temperature, hydrogen partial pressure, stress level, exposure time, steel composition and structure.

Microstructure shows presence of fissures from ID due to HTHA Depth of Hydrogen Attack can also be calculated
