Surface marking melts a thin layer and leaves a light or dark contrast with no measurable depth. Annealing marking heats stainless or titanium below the melting point so a black oxide forms; the surface stays smooth and corrosion resistance is preserved, which matters for food and medical parts. Engraving vaporises material in repeated passes and leaves a groove you can feel. Ablation removes a coating, paint, anodised layer or powder coat to reveal the base metal underneath.","Choose annealing for stainless nameplates and surgical instruments, engraving for parts that will be painted or that face sand abrasion in the Gulf, and ablation for backlit control panels and anodised aluminium plates.",{"headers":20,"rows":26},[21,22,23,24,25],"Process","Depth","Contrast","Cycle time for 30 mm text","Best material",[27,33,39,45],[28,29,30,31,32],"Surface marking","0.001 to 0.01 mm","light or dark grey","2 to 5 s","steel, aluminium, brass",[34,35,36,37,38],"Annealing marking","0 mm (oxide only)","black","10 to 30 s","1.4301 (304), 1.4404 (316L), Ti Grade 5",[40,41,42,43,44],"Deep engraving","0.05 to 0.5 mm","recessed, may be paint filled","30 to 300 s","steel, brass, aluminium",[46,47,48,49,50],"Ablation","coating thickness","base metal on coloured ground","2 to 10 s","anodised aluminium, powder-coated steel",null,{"heading":53,"paragraphs":54,"table":57,"bullets":51},"Materials and laser type",[55,56],"Fiber lasers at 1064 nm mark all metals and most dark engineering plastics.
