16GS - 15ga tube, round, rod

16GS - 15ga tube, round, rod

Supplier — AvecGlob Company — offers at a reasonable price from the manufacturer a circle, rod, pipe, which are made of structural steel grade 16GS (15GA). The supplier guarantees the timely delivery of products to any address specified by the consumer /

Technical specifications

Low-carbon steel grade 16GS (in Poland, steel is produced under the brand name 15GA) is a low-alloy steel containing an increased percentage of manganese and silicon. In the USA, this steel is produced according to the ASTM A633 standard and has the designation Gr. B / UNS K01803.

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 16GS (15GA) is widely used for the manufacture of plate, flat, ribbon, sheet and wire reels, square bars, other supporting elements of steel structures, forged casings of large valves, rings, multi-stage shafts with quiet operation. It is often used as a boiler steel (the manufacture of pipelines, auxiliary equipment and heat exchangers for boiler plants).

Chemical composition

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

C Si Mn Ni S P Cr V N Cu As
0.12−0.18 0.7 — 0.8 0.9 — 1.2 up to 0.3 up to 0.035 to 0.03 up to 0.3 up to 0.12 up to 0.008 up to 0.3 up to 0.08

When smelting steel is deoxidized by aluminum in a volume of 0.02… 0.06%.

Physical and mechanical properties

  • density, kg / m 3 — 7840;
  • melting point, 0 С -1520;
  • coefficient of thermal expansion in the temperature range 20… 100 0 С, μm / deg — 14;
  • modulus of elasticity, GPa — 192;
  • coefficient of thermal conductivity in the temperature range 20… 100 0 С, W / mgrad — 23;
  • Specific heat, J / kggrad — 411;
  • hardness according to Vickers, НV — not less than 345;
  • limit of temporary resistance, MPa — not less than 530;
  • yield strength, MPa — 350… 430 (depending on the assortment);
  • Relative narrowing of the cross-sectional area. % — 33;
  • permissible tensile elongation,% — 23.

Assortment and application features

Circle, pipe and rod of low-alloy steel 16GS (15GA) are produced in a wide range of cross-sections and lengths. Mechanical machinability and weldability — without restrictions. The critical range of pressures at which the material does not lose its integrity is up to 35 MPa. The ductility of steel at room temperatures is satisfactory (only the separation operations). The temperature range of forging is 820… 1200 0 С.

Supplier — AvekGlob Company — offers to buy a rod, pipe or a circle of structural low-alloy steel 14G2 (17Mn4, P295GH) 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.
