The SZ-Steel family of steel grades features low impurity levels and controlled grain sizes, and is proven to retain its properties in temperatures down to –40°C, and in extreme cases, has been tested to withstand temperatures as low as –101°C, according to the manufacturer. The specific design properties of the steel help to reduce risks of embrittlement and fracturing. SZ-Steel grades meet key international safety standards, and their capabilities are proven in many applications, including stud bolts, hydraulic equipment, drilling tools, axles and valves that are used in the oil-and-gas industry, mining and energy generation. — Ovako AB, Stockholm, Sweden
