16G2AF - p460n - s420n pipe, round, rod
Supplier — AvekGlob Company — offers at a reasonable price from the manufacturer a circle, bar, pipe, which are made of structural steel grade 16G2AF (P460N, S420N). The supplier guarantees the timely delivery of products to any address specified by the consumer.
Low-carbon steel grade 16G2AF (the closest foreign analogues — steel P460N, S420N) is a high-quality structural steel that contains an increased percentage of manganese and vanadium. According to the standard, DIN EN has the designation 1.8905.
The presence of vanadium gives the steel increased characteristics of ductility and toughness. In the absence of contact with aggressive chemical media, this steel retains its macrostructure and strength characteristics in a wide range of temperatures — from -75 0 С to +350 0 С.
Urgency of application
Steel grade 16G2AF (P460N, S420N) is widely used for the manufacture of boilers, pressure vessels and pipelines transporting hot liquids. In construction it is used for the production of welded structures operating over a wide range of temperatures, including negative ones (up to -30 ° C).
According to the technical requirements of GOST 19281−2014, 16G2AF steel comprises the following elements (numerical data — in percentages):
|0.14−0.20||0.3 — 0.6||1.3 — 1.7||up to 0.3||up to 0.035||to 0.03||up to 0.4||0.08−0.14||up to 0.3||up to 0.08|
During smelting, steel is saturated with bound nitrogen in an amount from 0.015 to 0.025%.
