troless nickel plating. Processing ferrous parts in a molten salt bath imfatigue proves metal hardness, strength, wear properties, and corrosion resistance. The SBN treatment produces two distinct microstructural zones-on the surface a shallow, hard, ductile case of epsilon iron nitride is formed; beneath it lies a much deeper nitrogen diffusion zone. Low operating temperatures and controlled cooling during SBN processing produces distortion-free results, allowing machining to be performed prior to SBN processing.
distribution of hot air at a stable temperature that will not improve important lubricants. It is particularly useful for batch drying or for drying small, delicate, or intricate items.

L&R’s Industrial Dryer is designed to dry items quickly and thoroughly, eliminating spots, preventing rust and corrosion, and saving time. The convection air flow from L&R’s customdesigned heat deflector creates an even
offers a uniform, highly protective coating for cyanide, alkaline noncyanide, and chloride zinc deposits. It performs effectively in operations where dip times of up to 90 seconds are indicated by equipment requirements. Because is does not contain hexavalent chromium, the use of this single-component liquid concentrate results in easy waste treatment processes.
