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.

The product is supplied with 3.1.B inspection certificate, according to the standards EN 10204 and ISO 10474.
Identification and Marking
Steel Pipe are marked in indelible ink, the details being repeated along the entire length of each tube and on a label, as follows:
Manufacturer’s trademark – manufacturing standard – dimensions -steel grade – supply condition – cast no. – item number.
Seamless Steel Pipe Process: Round bar→punched→grinded surface→annealed→grinded surface→acid pickling→cold rolled→annealed→Acid pickling or polished→cutting length→package
Inspection and Test
Chemical, Tensile test, intergranular corrosion, flat test, expand test, nonmetallic inclusion, hydraulic test.
Tubes will bundled by steel strip and not exceed 3 tons each batch. If thin wall thickness, we will put it into wooden case.
