ASTM A249/ASME SA249 stainless steel tube covers nominal wall thicknesses welded and heavily cold-worked welded pipes made of the following materials

Various grades of austenitic steel for boilers, superheaters, heat exchangers, or condenser pipes.

ASTM A249/ASME SA249 Stainless Steel Tube

YUHONG GROUP provides the best ASTM A249/ASME SA249 Stainless steel tubes including welded austenitic alloy steel boiler tube, superheater and heat exchanger tube, and U bending tube.

ASTM A249/ASME SA249 Stainless Steel Tube

ASTM A249/ASME SA249 stainless steel tube has good plasticity, low strength, and hardness. At the same time, ASTM A 249 also has a certain toughness, but it is not ferromagnetic.
ASTM A249/ASME SA249 stainless steel tube is not only resistant to oxidative acid medium corrosion, but also resistant to sulfuric acid, phosphoric acid, formic acid, acetic acid, urea, etc. if it contains Mo, Cu, and other elements. If the carbon content of ASME SA249/ASTM A249 tubing is less than 0.03% or contains Ti and Ni, the resistance of this SS steel tube to intergranular corrosion can be significantly improved.
