Sub-zero reliability
Published:  25 March, 2015

OVAKO says as companies push the limits of performance in cold climates and harsh sub-zero Arctic environments, demand for strong, safe and well-proven materials is on the rise. Components like pipeline bolts, hydraulic parts and offshore lifting devices must offer greater reliability at -50°C or lower sub-zero temperatures.

Ovako says its SZ-Steel is proven to retain its properties in temperatures down to -40°C and beyond and, in extreme cases, is well-tested to withstand temperatures down to -101°C. As one of the Ovako attribute brands, SZ-Steel designates a grouping of steel grades across a range of products in the company’s portfolio including BQ-Steel, IQ-Steel, M-Steel and WR-Steel.

SZ-Steel, which stands for sub-zero, is a family of steel grades with low impurity levels and controlled grain size that are specifically developed, designed and produced for use in extreme environments.
