Ham-Let Introduces PuRight [Professional Services Close - Up]

(Professional Services Close - Up Via Acquire Media NewsEdge) Ham-Let reported it launched PuRight - a new, enhanced stainless steel 316L material at Semicon West.

According to a Company release, PuRight material - an enhanced version of 316L Stainless Steel - offers, lower inclusion content, low Carbon content for enhanced welding, low Sulfur content for enhanced electro-polishing and better corrosion resistance achieved by modification of key elements, such as: chromium (Cr), Molybdenum (Mo) and Nickel (Ni).

"Our newly-developed PuRight material is far more resistant to corrosion than previously available materials and less likely to pit than conventional 316L stainless steel," said Felix Shestatski, VP Quality, Engineering and R&D at HAM-LET. "PuRight material is designed to achieve optimum surface quality after mechanical or electro-polishing processes. It is compatible with the SEMI-F20 standard, as well as with ASTM-A276 and ASTM-A479/ASME SA479 standards".

The Company noted that the new product features resistance to pitting and crevice corrosion - especially in the presence of free- Chloride (Cl-) ions - and with its inherent properties, demonstrates improved performance in strongly-oxidizing acid media.

"This uniquely-designed alloy has a clear advantage in use for pressure or flow control devices, such as valves, fittings etc. With its excellent welding characteristics and meaningfully-high values of CPT, as well as high ratios of Cr/Fe and CrOx/FeOx, PuRight material should prove highly attractive to manufacturers of Ultra High Purity (UHP) products and is particularly well suited for use in the semiconductor industry," Shestatski concluded.

Ham-Let Group specializes in the design, development production and marketing of instrumentation valves and fittings.
