A268 TP410 Martensitic Stainless Steel Seamless Tube, For Reheaters In Thermal Power Plants

Overview of TP410 Martensitic Stainless Steel Seamless tube

Through heat treatment can adjust its mechanical properties of stainless steel, in general, is a class of hardenable stainless steel. Typical grades are Cr13 type, such as 2Cr13, 3Cr13, 4Cr13, etc. After quenching, the hardness is high, and different tempering temperatures have different strength and toughness combinations, mainly used for steam turbine blades, tableware, and surgical instruments. According to the differences in chemical composition, martensitic stainless steel can be divided into two categories: martensitic chromium steel and martensitic chromium-nickel steel. According to the differences in organization and strengthening mechanism, it can also be divided into martensitic stainless steel, martensitic and semi-austenitic (or semi-martensitic) precipitation hardening stainless steel and martensitic ageing stainless steel, etc.

Characteristic of TP410 Martensitic Stainless Steel Seamless tube

Grade 410 stainless steel is a general-purpose martensitic stainless steel containing 11.5% chromium, which provides good corrosion resistance. However, the corrosion resistance of Grade 410 steel can be further improved through a number of processes including quenching, tempering and polishing. Quenching and tempering harden Grade 410 steels. They are typically used in applications involving mild corrosion, heat resistance and high strength.
