ASTM A268 TP410 Seamless Tubing has good corrosion resistance along with high strength and hardness. In the annealed condition, SS 410 Tubing is ductile and may be formed. ASTM A268 TP410 Polish Tubes are suitable in environments containing weak or diluted acetic acid, naptha, nitric acid and sulfuric acid. SS 410 Seamless Tube is best machined in the annealed condition at surface speeds of 60 – 80 feet (18.3 – 24.4m) per minute.
Product Standard: ASTM A268
Main steel grades: TP405,TP409,TP410
Application: It is generally used for applications which involve mild corrosion, high strength, and heat resistance.
