What material is required for nameplates on ASME containers manufactured after November 1, 1994?

The correct answer is stainless steel, which is mandated for nameplates on ASME containers manufactured after November 1, 1994, due to its durability, corrosion resistance, and ability to withstand harsh environmental conditions. Stainless steel ensures that the labeling remains legible and intact over time, which is crucial for safety and compliance with regulatory standards.

This requirement helps ensure that vital information about the container, including its specifications, capacity, and regulatory compliance, remains protected against wear and tear, thereby enhancing safety in the handling and transportation of compressed natural gas. Other materials, while they may offer some benefits, do not provide the same level of longevity and resistance to degradation that stainless steel does, making it the superior choice for this application.
