QS25T Sanyo Ferritic Heat-resisting Stainless Steel Seamless Pipe for heater tube

QS25T Sanyo Ferritic Heat-resisting Stainless Steel Seamless Pipe for heater tube

1.Applications:

Ferritic grades have been developed to provide a group of stainless steel to resist corrosion and oxidation, while being highly resistant to stress corrosion cracking. These steels are magnetic but cannot be hardened or strengthened by heat treatment. They can be cold worked and softened by annealing. As a group, they are more corrosive resistant than the martensitic grades, but generally inferior to the austenitic grades. Like martensitic grades, these are straight chromium steels with no nickel. They are used for decorative trim, sinks, and automotive applications, particularly exhaust systems.
