ASME SA213 T5 Alloy Steel Tube Seamless Hot Rolled for Boiler Heat Exchanger Application
ASME SA213 T5 Alloy Steel Tube Seamless Hot Rolled for Boiler and Heat Exchanger Application
ASTM A213 is a standard for seamless ferritic/austenitic alloy steel tubes for boilers, superheaters, and heat exchangers, and T5 is the specific material grade under this standard. T5 belongs to medium chromium molybdenum alloy steel, which has high temperature oxidation resistance and creep resistance, and is suitable for high-pressure and high-temperature environments.
Specification
Outside diameter:3.18-810mm
Wall thickness:0.2-40mm
Max.Length; 50m
Surface:Pickling and annealing,pickling and annealing+polishing+ EP(Electricity polish)
The core advantages of ASME SA213 T5 alloy seamless tubes lie mainly in their excellent high-temperature strength and creep resistance, good oxidation and corrosion resistance, good structural stability and tempering stability, and good thermal conductivity.
