ASTM A249 TUBING FEATURES
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 SA249pipe stainless 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.
