The company Electrocentury-steel offers to buy pipe, round, rod of low carbon alloy steels 12KH2N4A, and 1.5752 15NiCr13. The supplier guarantees the best price from the manufacturer. Ensured compliance with the assortment of supply and prompt delivery of goods to the point specified by the user.
Properties and applications
Steel under consideration belong to the group of nitride, which provides high strength high content of nitrides in their microstructure. Therefore, these steels are manufactured of high-strength parts of hoisting machines and mechanisms that require the optimum combination of high surface hardness with the necessary toughness of the core. Such parts include worm and regular shafts, couplings, Cams, rods etc. Welding of steels 12KH2N4A, 15NiCr13 1.5752 and should be performed under the flux layer, and machining lead using carbide tools.
Basic physical and mechanical properties after hardening:
- Tensile strength, MPa — 1150;
- Yield strength, MPa — 950;
- Elongation, percent — 15;
- The relative narrowing, % — 50;
- Impact strength, kJ/m2 — 800.
To by pipe, rod, circle of structural alloyed steel grades 12KH2N4A, and 1.5752 15NiCr13, the company offers Electrocentury-steel. The price is from the manufacturer. The supplier guarantees the implementation of the range supplies products, as well as their prompt transportation to the consumer.
