Is 22 HRC the right threshold for TMCP large diameter pipes in severe sour environment?

Product Number: 51323-18943-SG

The manufacturing and field experience of high strength low alloy (HSLA) steel plates produced by Thermo-Mechanical Controlled Process (TMCP) are well defined in industry standards and literature. The TMCP method consists of a well-prescribed rolling pass schedule followed by accelerated cooling that leads to a fine-grain microstructure with the desired mechanical properties of the produced plates.
Quite recently, this TMCP process resulted in detrimental local variations with hidden hardness variations on pipe ID, so-called Local hard Zones (LHZ).

Local Hard Zones On TMCP Large Diameter Line Pipes: What Do We Know?

Product Number: 51322-17565-SG

Author: Hervé Marchebois, Bruce Cowe, Thierry Cassagne

Publication Date: 2022

The current paper deals with a thorough analysis of these newly recognized LHZ with Scanning Electron Microscope (SEM) and Electron Back Scattering Diffraction (EBSD) investigations through the wall thickness of pipes. Internal diameter (ID) surface, intermediate zone and bulk metal microstructures showed an increase of a strong misorientation while approaching the ID. Thus, LHZ is characterized by the presence of lath and especially lower bainite type microstructures associated to high local hardness above the NACE MR 0175 / ISO 15156 limits for sour service applications.

Long-Term Aging Behavior Of Cold-Worked Alloy 690 In Simulated PWR Primary Water

Product Number: ED22-18358-SG

Author: Ziqing Zhai, Matthew J. Olszta, Mychailo B. Toloczko

Publication Date: 2022

Alloy 690 has been utilized since the late 1980s as a replacement for Alloy 600 in pressurized water reactors (PWR) pressure boundary components due to laboratory data indicating higher resistance to stress corrosion cracking (SCC). Although to date no SCC incidents have been reported on Alloy 690 components in service, the growing interest of extending the operation life of PWRs beyond 60 or even 80 years has raised concerns for the potential occurrence of long-range ordering (LRO) in Alloy 690 and its compatible weld metals.

Optimized Hardness Measurements for Micrometric Coatings in Disc Brake Components

Product Number: 51324-20993-SG

Publication Date: 2024

The manuscript describes an optimized analytical protocol for the measurement of hardness and Young’s modulus in micrometric Sol-Gel coatings for brake components. In particular, two different hybrid organic-inorganic coatings with different functional properties are presented as example. The work pays particular attention in developing and optimizing reliable hardness measurements procedures by coupling Focus Ion Beam Scanning Electron Microscopy (FIB-SEM) and Nano-Indentation (NI) probes. In particular, FIB-SEM is used to directly assess the actual coating thickness, avoiding any eventual damaging and artifact in thin layers possibly due to classical metallographic sample preparation. Once the thickness of the investigated coating is determined, then it is used as input parameter to calculate proper indentation penetration depth and load for NI measurements, thus avoiding any influence of the substrate in the obtained results. Finally, it is demonstrated that the proposed analytical protocol provides stable, reproducible and reliable hardness measurements in thin Sol-Gel coatings.
