The Role of Tungsten on the Phase Transformation Kinetics and its Correlation with the Localized Corrosion Resistance of 25Cr Super Duplex Stainless Steels

May 29, 2020 by Mariano Iannuzzi

This investigation demonstrated 2.1 wt% tungsten drastically reduced the kinetics of tertiary phase precipitation in 25Cr super duplex stainless steels. The slow kinetics resulted in a better overall pitting corrosion resistance.

Maximum allowable service temperatures and the ASTM G48 test

November 29, 2013 by Mariano Iannuzzi

Can we use the ASTM G48 test to establish the maximum allowable temperature of a metal or alloy in an oxidizing environment like seawater?
This post discusses how the ferric chloride electrolyte of the ASTM G48 test compares with other oxidizing environments such as seawater.
