A209 T1B Seamless Alloy Boiler Pipe
GNEE sells over 1,500 tons of seamless and welded steel pipes annually to various engineering industries. Our goal is to ensure that our customers have the highest expectations for the delivery and product quality of ASTM A209 T1 B Alloy Seamless Steel Pipe.
SA209 T1b grade alloy steel seamless pipe is a carbon steel pipe with subsequent addition of chromium, molybdenum and sometimes vanadium, known as chrome molybdenum pipe. ASTM specification alloy steel pipe is used for high temperature service applications. According to SA209 T1B grade, this SA209 T1B seamless pipe has a minimum tensile strength of 415 MPa and a minimum yield strength of 220 MPa.
SA209 T1b boiler pipe has excellent mechanical properties and corrosion resistance, and is widely used in boilers, boiler flues, superheaters and other fields.
