ASTM A789 UNS S32750 is a super duplex stainless steel widely used in applications requiring high strength and corrosion resistance.

A333 and A334 refer to two different specifications for low-temperature carbon steel pipes.

The composition of 12Cr1MoV alloy steel usually includes 0.08-0.15% carbon, 0.40-0.70% silicon, 0.40-0.70% manganese, 0.30-0.60% molybdenum, 0.40-0.55% chromium, 0.15-0.25% vanadium and a small amount of elements. Other alloying elements.

ASTM A847 weathering steel pipe is a cold-formed welded and seamless high-strength, low-alloy round, square, rectangular or special-shaped structural pipe.
