Total Materia has allowed us to solve in a definite way all problems we had for the search of alternate materials in foreign countries. Thanks to Total Materia we have issued real "international" specs for purchase of steels in foreign countries.
Total Materia remains the only tool which will be used for this purpose.

Known also by a range of synonyms, Stress-Relief Cracking (SRC) is intergranular cracking in the heat affected zone (HAZ) or weld metal that occurs during exposure to in-service temperatures or post-weld heat treatments.
Identified by the appearance of liquid films along grain boundaries or to another location in the material structure, hot cracking can be divided into several categories.
Superalloys have been developed for key applications which typically require a combination of high temperature strength, toughness, and resistance to degradation in corrosive or oxidizing environments.
