general characteristics

Nickel alloy composed HN65MV significantly reduces the critical quenching rate. Nickel began to acquire the ability to pass-through tempered, even for large sizes of the product. Nickel improves the toughness, yield strength and strength at the same time does not reduce the viscosity. At equal strength nickel steel is always more malleable. Effect on the mechanical properties of nickel range amplified after quenching and tempering treatment. Additive increase molybdenum gives resistance to acids. Circle HN65MV extremely corrosion-resistant, can withstand 48 hours in boiling 30% sulfuric acid with the addition of ferrous sulphate. The combination of exceptional corrosion resistance, high ductility, reliability, performance over a wide temperature range, simple welding — make a circle indispensable in many branches of modern industry.

The chemical composition of the circle HN65MV

Treatment

Welded by electric arc or argon-arc way. At the same time as a filler material or wire HN65MV HN65MVU. The welding seam is resistant to corrosion and cracking.

disadvantages

Addiction circle HN65MV to work hardening, require low cutting speeds, with obligatory use of tools, equipped with plates from high-speed steel, have such a range of high production costs. However, considering a high strength and, consequently, durability, possibility of recycling the material — it reduces the high cost of practically long term investment. Contamination iron alloy, carbon and silicon causes intergranular corrosion. In addition to reducing the content of these elements other means no corrosion control.

application

Production of welded chemical equipment. intended to operate in the most corrosive environments at t ° from -70 to + 500 ° C. Such terms are commonly used in the pulp and paper industry, mechanical engineering, nuclear power. It is claimed for the manufacture of machines and installations for the production of synthetic non-metallic materials such as glass, fiberglass, plastic and the like. D., Fertilizers and others. Chemical products, it is indispensable for the medium with hydrochloric, sulfuric, nitric or phosphoric acid.
