646.SA

The 646.SA from Ideal-Tek is an anti-magnetic anti-acid stainless steel general purpose tweezer. This tweezer is handcrafted to have perfect tip symmetry and balance along with polished edges and superior no-scratch/antiglare satin finish. It contains from 16.5 to 18.5 wt% chromium and has important quantities of nickel and molybdenum as additional alloying elements. This tweezer is generally used where corrosion resistance and toughness are primary requirements. It is used by electronic industry, watchmakers, jewellers, microscopy, laboratory and medical applications in moderately aggressive chemical environments.
