Technical FAQs — Zeron 100 MTC Certificate
Why are Copper (Cu) and Tungsten (W) highlighted on this MTC?
Zeron 100 (UNS S32760) is a highly alloyed Super Duplex stainless steel. Unlike standard 2205 or other Super Duplex grades (like 2507), S32760 requires specific additions of Copper and Tungsten (both 0.50% to 1.00%). As verified in the MTC, these additions act synergistically to greatly enhance the alloy's resistance to strong reducing acids (like sulfuric and hydrochloric) and localized corrosion in marine environments.
What heat treatment methodology is tracked on this certificate?
The MTC logs a Solution Annealing phase followed by a rapid Water Quench. Because Zeron 100 is highly alloyed, a very fast quench is critical to avoid the precipitation of detrimental intermetallic phases (like sigma phase) and to maintain the ideal 50/50 austenite-to-ferrite microstructural balance.
Are the materials free from radioactive contamination?
Yes, the document strictly states that the material is free from radioactive contamination and undergoes a 100% visual inspection to ensure it is free from defects.
