Isotropic steel can lighten hydraulic components
An
Ovako Steel AB product story
Edited by the Manufacturingtalk editorial team
Feb 4, 2004
Intended for use in the manufacture of highly stressed hydraulic components, an isotropic steel has high impact strength coupled with high yield strength, leading to lighter assembly weight.
Ovako Steel has launched Ovahyd 650, the company's new hydraulic steel, developed mainly for the manufacture of highly stressed hydraulic components.
This new steel has high impact strength coupled with high yield strength.
These properties make it possible to manufacture hydraulic cylinders with thinner walls, creating an opportunity to design and develop much lighter cylinders with superior performance in service.
Ovahyd 650 is the flagship product within Ovako Steel's new trade named range.
Ovako Steel's new Ovahyd 650 hydraulic steel has been developed from existing steels but with an improved yield strength of 650Mpa (94,000 lb/in2), and excellent impact strength down to - 40degC.
Ovahyd 650 is an isotropic steel ensuring that its properties are uniform in all directions.
The high fatigue strength is achieved partly as a result of the superior cleanliness of the steel, making Ovahyd 650 eminently suitable for hard chromium plating.
Developed for the hydraulic industry - "With the introduction of Ovahyd 650, we launch an entirely new family of steels developed specifically for the hydraulic industry", explains Bjorn Olsson of Ovako Steel.
The Ovahyd trade name makes it easier for hydraulic cylinder manufactures to find steel with the mechanical properties best suited to their particular needs.
With fundamental properties based on the advantages of micro-alloyed steels, combined with the characteristics of hardened and tempered steels, Ovahyd 650 provides a cost effective solution to the requirements of the hydraulic industry.
The new steel was developed for the manufacture of hydraulic components subject to high stresses, e.g cylinders and piston rods.
Ovahyd 650 is low carbon steel alloyed with chromium, molybdenum, nickel and vanadium to enable its outstanding strength properties.
The steel is produced according to the same principles that apply for bearing steels with an accurately defined process procedure that gives a very high cleanliness as well as maximum precision and uniformity.
Ovahyd 650 is supplied in the martensitic, high-temperature tempered condition ensuring that, in contrast to today's ferritic-perlitic micro-alloyed steel, the basic structure is always homogeneous.
With the new steel, the hydraulic components can be manufactured with a lower structural weight without sacrificing strength and safety.
- "Ovahyd is the first member of our new family of steels and additional members will be released during 2004", concludes Olsson.
