New stainless steel material grades

in small spaces, and voltage convertor for both 110 and 220-volt power. The machine has a compact design and weight of only 9kg for easy movement around crowded automotive facilities. In addition, there is excellent performance and consistent high quality cuts, and long lasting consumables that are quickly and easily replaced. Judges found the Powermax30 to be a good value for the money, and the system passed all life tests and presented no problems with durability. The organisation even commended Hypertherm for its user’s manual, which it found was written clearly and contained appropriate information. Hypertherm designs and manufactures advanced plasma cutting systems for use in a variety of industries such as shipbuilding, manufacturing, and automotive repair. Its product line includes handheld and mechanised plasma systems and consumables, as well as CNC motion and height controls.

Sandvik has introduced two new stainless steel grades, Sandvik SAF 2707 HD ® and Sandvik Sanicro ® 25. 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  Sandvik Sanicro ® 25, is designed for use in high efficiency pulverised coal fired steam boilers

general corrosion. At the same time, it 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. Sandvik Sanicro 25 has been developed for use in advanced ultra-supercritical 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°C, helping to boost efficiency. The increased steam temperature contributes to higher efficiency, lower carbon dioxide emissions and reduced fuel consumption, helping to meet the environmental demands of the future.
