310S stainless steel pipe is preferred over 310 for heat exchangers due to its lower carbon content, offering better weldability and reduced risk of carbide precipitation at high temperatures.

Stainless steel 1.4404 pipe is a low-carbon, molybdenum-alloyed austenitic grade known for excellent corrosion resistance, especially in chloride-rich environments.

The ASTM equivalent of 1.4410 stainless steel is UNS S32750, commonly known as Super Duplex 2507.

316L stainless steel pipe is preferred over 304 in the pharmaceutical industry due to its superior corrosion resistance and lower carbon content, which ensures better purity and weld integrity in high-sanitation environments.

SS 347 stainless steel pipe offers better high-temperature resistance and intergranular corrosion resistance than SS 304, making it ideal for heat-intensive and welded applications.

ASTM A312 TP316L is widely used for subsea and onshore liquid ammonia transportation pipelines due to its excellent corrosion resistance and weldability in harsh environments.
