ASTM A268 Seamless TP410 Ferritic Martensitic Steel Tubes
TONG CHUANG Group offers ASTM A268 TP410 SMLS/WELDED ferritic martensitic stainless steel tubes and we sell these tubes in more than 70 countries up to now. This specification covers a number of grades of nominal-wall-thickness， stainless steel tubing for general corrosion-resisting and high-temperature service.
Grade TP410 ferritic martensitic stainless steel， with 11.5% chromium， which provide good corrosion resistance properties. What's more， the corrosion resistance of grade 410 steels can be further enhanced by a series of processes such as hardening， tempering and polishing. Quenching and tempering can harden grade 410 steels.However， it doesn't be suitable for highly corrosive environments containing strong acids or chlorides. In such cases， a more corrosion-resistant stainless steel grade， such as TP316 or TP304， may be preferred.
And TP410 this material offers good strength， hardness， and wear resistance， making it suitable for demanding environments.
