Ovako Steel has developed a new steel for the manufacture of highly stressed hydraulic components. The steel, called Ovahyd 650, is intended for use in the manufacture of hydraulic components subject to high stresses, for example cylinders and piston rods. The new steel allows hydraulic components to be manufactured with a lower structural weight without sacrificing strength and safety.

Ovahyd 650 is a low-carbon steel alloyed with chromium, molybdenum, nickel and vanadium hydraulic steel, with a yield strength of 650 Mpa and an impact strength down to -40° C. An isotropic steel, Ovahyd 650’s properties are uniform in all directions.

The high fatigue strength is achieved partly as a result of the cleanliness of the steel, making Ovahyd 650 suitable for hard chromium plating.

“With the introduction of Ovahyd 650, we launch an entirely new family of steels developed specifically for the hydraulic industry,” says Björn Olsson of Ovako Steel.
