D6AC steel enables stainless steel piping and fittings to withstand extreme conditions.This medium-carbon, low-alloy, ultra-high-strength steel offers strength up to 280,000 psi, excellent flexural strength ratios and good ductility.
With notch toughness down to -210°F (-134°C), D6AC is a key player in critical applications such as aerospace.It is produced using a vacuum arc remelting process that ensures cleanliness and optimal structure for optimal performance.

Core Advantages of D6AC
With an excellent strength-to-weight ratio, thinner, lighter tubing can be manufactured without compromising on durability. Ideally suited for aerospace applications to reduce weight while ensuring system safety.
Resists impacts and stops fittings from cracking in cold or high pressure conditions. Remains indestructible in temperatures as low as -134 degrees Celsius. Ensures that pipes work in the harshest environments.
Thanks to the presence of chromium and molybdenum, a natural rust barrier is created to protect the pipe from moisture or chemical corrosion, and its durability lasts for decades.
Fast welding speeds accelerate the production of stainless steel fittings without tedious preparation. Its strong, seamless welds effortlessly reduce rework and maintenance costs.
