Designation GOST Latin 06X1F
Transliteration 06H1F
By chemical elements 06Cr1V

Description

06Х1Ф steel is used: for the manufacture of pipes with diameter from 57 to 168 mm for use in the system of gas pipelines, oil and gas pipelines, technological pipelines, transporting oil and oil products, as well as in the systems of reservoir pressure maintenance in terms of climatic zones with temperature of the transported medium from +5° C to +40° C.

Note

Structural micro-alloyed steel of higher corrosion resistance and cold-resistance. The pipes are from gas & oil pipes standard high cold resistance, high resistance to General and pitting corrosion, resistance to sulfide corrosion cracking and hydrogen cracking.
