15X - 15Cr3 - aisi 5115 circle, rod, forging

15X - 15Cr3 - aisi 5115 circle, rod, forging

Supplier — the company Avecho offers at affordable prices from the producer circle, rod, forgings, which are made of steel 15KH (15Сг3, AISI 5115). Supplier guaranteed timely delivery at any address specified by the consumer.

Technical characteristic

Low carbon steel brand 15X (the closest foreign analogues — 15Сг3 steel, AISI 5115) is a structural steel, alloy chrome. Steel is not prone to intergranular corrosion, its high ductility in hot and cold metal forming suitable for the production of prefabricated steel structures of complex shapes. Hardenability of the material is negligible. Has good heat resistance and wear resistance at moderate sliding speeds.

The urgency of the application

Due to its high machinability, wear and heat resistance steel 15KH (15Сг3, AISI 5115) used in the technologies of automatic lathe production of bolts and nuts, used in decorative architectural details, units for railway vehicles, conveyor steel belts, fittings, items of household boilers and heat exchangers.

Chemical composition

According to the technical requirements of the standard GOST 4543−91 in the composition of steel 15KH includes the following elements (numerical data in %):

C Si Mn Ni S P Cr Cu
0.12 — 0.18 0.17 — 0.37 0.4 — 0.7 To 0.3 up to 0.035 up to 0.035 0.7 — 1.1 to 0.3

Assortment and application of

Round, rod and forgings of alloy steel 15KH (15Сг3, AISI 5115) are produced in a wide range of cross-sections and configurations. Machinability and weldability is good, however the material is not recommended for use in formoizmeneniya operations of cold forming. In the presence of carbon dioxide compounds, the corrosion resistance is markedly reduced. Temperature range of forging — 820 1200…Zero C.

Supplier — the company Alekhlas — offers to buy rod, circle, or forgings of low carbon structural steel 15KH (15Сг3, AISI 5115) in the required range of cross sections, weight and configuration. Products can be purchased at a price formed on the basis of European and world standards of production. Possible, wholesale and retail, for regular customers a flexible system of discounts.
