Product Description

The "T12" designation refers to Grade T12, a low-alloy steel containing 1.25% chromium and 0.5% molybdenum, offering excellent high-temperature strength.

Provides superior resistance to creep and oxidation, making it ideal for demanding power plant applications.

Chromium and molybdenum content enhances corrosion resistance in high-temperature environments.

Serrated fins increase surface area for optimal heat dissipation or absorption.

High-frequency welding process ensures cost-effectiveness and production efficiency.
