Enhanced machineability SS hollow bar size grows
Enhanced machinability stainless steel hollow bar for makers of valves, pumps and so on - and available in over 100 different sizes - is now stocked in sizes up to 420mm outside diameter.
Super thin SS conveyor belts are stronger
A breakthrough in steel belt processing technology has enabled a steel producer to launch a range of strong, super thin stainless steel conveyor belts to replace weaker plastics ones.
The company will be showing two new grades, Sandvik SAF 2707 HD and Sandvik Sanicro 25.
* Hyper-duplex stainless steel - the Sandvik SAF 2707 HD is a hyper-duplex stainless steel, specially developed for service in highly corrosive conditions, such as seawater cooled heat exchangers.
It is particularly suited to aggressive, chloride-containing environments and displays excellent resistance to pitting and crevice corrosion, stress corrosion cracking and general corrosion.
Sandvik told manufacturingtalk.com that at the same time, the SS has high mechanical strength and good weldability.
Particularly aimed at the chemical, petrochemical and refinery industries, Sandvik SAF 2707 HD has been developed to meet higher industry demands on performance whilst maintaining the reliability and safety of equipment.
* Creep resistant austenitic SS - also being shown for the first time is Sandvik Sanicro 25 for use in advanced ultra-super-critical coal fired steam boilers, destined for the next generation of power stations.
Specially designed for reheater and superheater tubes, Sandvik Sanicro 25 is a creep resistant austenitic material that allows for material temperatures up to 700 deg C, helping to boost efficiency.
The increased steam temperature contributes to higher efficiency, lower carbon dioxide emissions and reduced fuel consumption.
This gives valuable help towards meeting the environmental demands of the future, said Sandvik.
