Designation
Description
12Г2МФТ steel is used: for the manufacture of electro-welded anchor chains increased accuracy; details of railway bridges North of execution.
Note
Rolled steel 12Г2МФТ thickness up to 40 mm is characterized by not only higher strength but also higher performance of fracture toughness in a wide temperature range.
Standards
Chemical composition
Fe is the basis.
According to TU 3-867-85 the chemical composition is presented for steel grade 12Г2МФТ-СШ. In the finished bars, with all the requirements of technical specifications, deviations in chemical composition are allowed: by carbon +0.010%, for silicon ± 0.050%, for manganese ± 0.050%, for titanium ± 0.020%.
