16G2AF - p460n - s420n pipe, round, rod

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.

Technical specifications

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).

Chemical composition

According to the technical requirements of GOST 19281−2014, 16G2AF steel comprises the following elements (numerical data — in percentages):

C Si Mn Ni S P Cr V Cu As
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%.

  • hardness in Brinell, HB — no more than 433;
  • limit of temporary resistance, MPa — 510… 600;
  • yield strength, MPa — 390… 450;
  • Relative narrowing of the cross-sectional area. % — 20;
  • permissible tensile elongation,% — not less than 11.

Assortment and application features

The circle, pipe and rod of construction low-alloy steel 16G2AF (P460N, S420N) are produced in a wide range of cross-sections and lengths. It is not recommended to use this steel in the production of complex non-spillable joints. Mechanical machinability and weldability — without restrictions. The temperature range of forging is 800… 1200 0 С.

Supplier — AvekGlob Company — offers to purchase a rod, pipe or a circle of low-alloyed structural steel 16G2AF (P460N, S420N) in the required assortment of cross sections and length. Products can be bought at a price formed on the basis of European and world standards of production. Implementation is possible in bulk and retail, for regular customers, a flexible system of discounts operates.
