A333 A334 Low Temp Carbon Pipe
A333 and A334 refer to two different specifications for low-temperature carbon steel pipes.
Corten Steel ASTM A242 Pipes are commonly used in construction and outdoor applications where the pipes are exposed to harsh weather conditions. They are also used in bridges, buildings & other structures where their high-strength and corrosion resistance properties are required. Additionally, they can be used for decorative purposes due to their unique rust like appearance.
ASTM A242 Corten Steel Pipes is an alloy steel grade made from iron, carbon, and other elements such as molybdenum, manganese, chromium, nickel, copper, and vanadium. Typically, these pipes feature between 0.25% and 0.50% carbon content, and the remainder are alloyed materials such as those mentioned above. The composition of the alloy steel can vary depending on the desired properties of the pipe itself. There are different grades available including ASTM A423 Grade 1 Pipes, ASTM A709-50W Pipes, etc.
