From 6Mo To Ni-Base – Characterizing The Corrosion Performance Of Two Important Material Groups

Product Number: 51322-17935-SG

Author: Björn Helmersson

Publication Date: 2022

$20.00

Stainless steels and Ni-base alloys are often considered as construction materials in applications where highly corrosive conditions are expected. High levels of halides, low pH and high temperatures are factors that often contribute to the selection of such materials.

Ten different alloys have been included in this work, representing a range of highly alloyed stainless steels and Ni-base alloys. The purpose has been to evaluate the corrosion resistance of stainless steels with alloying content in the 6Mo range or higher, and competing Ni-base materials. The austenitic grade N08904 and two super-duplex grades have also been included for reference.

How Fluoropolymers Resist Chemical Attack across the pH Spectrum

Product Number: 51324-20603-SG

Author: Jason Knapp

Publication Date: 2024

$40.00

When chemical process systems require extremely harsh or demanding environments, material selection is critical for providing longevity and preventing downtime. For systems utilizing exceedingly low or high pH chemicals, fluoropolymers are often an excellent choice to prevent corrosion in a system. The strong carbon-fluorine bond allows fluoropolymers to thrive in areas where other materials would be subject to failures. Strong acids are handled exceptionally well by many fluoropolymers, and certain copolymerization reactions with materials such as PVDF can provide a material that holds up to even more challenging situations. This paper will summarize the most commonly used fluoropolymers in the industry, as well as discuss applications where fluoropolymers are used. The paper will also detail why fluoropolymers can resist exceptionally aggressive chemicals, and how PVDF-HFP copolymers improve the corrosion resistance of both low and high pH environments. Case studies will also be provided.

Nonmetallic Materials of Construction for the Mining and Mineral Processing Industry

Product Number: 51323-18921-SG

Author: Alexandra Peters

Publication Date: 2023

$20.00

Mining is the essential process of extracting materials from the earth. It dates back to prehistoric times when the earliest humans mined flint, copper and gold. These basic materials were then used for tools, weapons, currency. Today, there is a wide array of mined products from the extraction of valuable materials. Mining is a growing industry with many varied processes and system designs depending on the extraction requirements, processing techniques, and restoration of the land after a mind is closed.

Uniform Corrosion Characterization of UNS N08935

Product Number: 51323-19294-SG

Author: Björn Helmersson, Marie Almén

Publication Date: 2023

$20.00

Highly alloyed stainless steels and Ni-based alloys may be used in a wide range of different chemical environments. By investigating how different alloys are affected by environmental changes – be it chemical composition, temperature, contaminants or others – it is possible to learn more about how material selection can be optimized to improve both cost efficiency and longevity of a system.

UNS N08935 is a highly alloyed austenitic material in the borderland between stainless steels and Ni-based alloys
