TP410
Material
TP410, S41000, 1.4006, X12Cr13, 1Cr13
Overview
TP410 is a martensitic stainless steel that provides good corrosion resistance, high thermal strength, hardness, toughness and cold deformation properties. Its shock absorption is also very good. It is magnetic in both the annealed and hardened conditions. A wide of properties can be achieved with different heat treatments. Applications requiring moderate corrosion resistance and high mechanical properties are ideal for this stainless steel.
Characteristics
TP410 stainless steel has good corrosion resistance and machinability.
The “straight-chromium” type tubing is characterized by being ferromagnetic. TP410 is amenable to hardening by heat treatment, and the high-chromium, ferritic alloys are sensitive to notch-brittleness on slow cooling to ordinary temperatures. These features should be recognized in the use of this materials.
Application
TP410, commonly known as “straight-chromium” type stainless steel tubing, is for general corrosion resisting and high temperature service.
TP410 is usually used for the production of weak corrosion resistance medium and load bearing parts, mainly used for higher toughness, certain corrosion resistance and impact load bearing parts, can also be made in the normal temperature conditions of weak corrosion resistance medium equipment and parts.

Heat treatment and hardness
TP410 can be hardened by cold working and heat treating.
High temperature or low temperature tempering is required, but tempering should be avoided between 370 and 560℃.
As a final heat treatment, tubes shall be reheated to a temperature of 1200 °F [650 °C] or higher and cooled (as appropriate for the grade) to meet the requirements of this specification.
Hardness: max. 207 HBW or 95 HRB
