The round tip delivers a consistent mark on metal surfaces, even in shop environments where liquid markers fail or smear. The solid paint formula bonds to bare metal and leaves a visible yellow line that survives handling prior to heat processing. This marker is a single-piece consumable used by heat-treat technicians, weld inspectors, and fabrication shop personnel who need a reliable, heat-process-compatible marking solution.\u003c\/p\u003e\n\u003cp\u003eThis marker is suited for ferrous and non-ferrous metal fabrication environments, including job shops, heat-treat facilities, forge operations, and structural steel fabrication floors. It applies directly to steel, iron, and aluminum workpieces before they enter furnaces, induction coils, or other heat-treating equipment. The compact solid-stick format makes it easy to store and carry on the shop floor.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid oil-base paint formula designed for pre-heat-treat and annealing marking applications\u003c\/li\u003e\n  \u003cli\u003eRound tip for consistent line deposit on flat and curved metal surfaces\u003c\/li\u003e\n  \u003cli\u003eYellow color provides high contrast against bare steel, iron, and aluminum\u003c\/li\u003e\n  \u003cli\u003eCompatible with steel, iron, and aluminum substrates\u003c\/li\u003e\n  \u003cli\u003eCompact single-stick format for easy handling and storage\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use on steel, iron, and aluminum surfaces in annealing and heat-treating applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eNo installation is required for this consumable marking product. Apply the marker directly to the workpiece surface before heat processing. Ensure the surface is reasonably free of heavy grease or scale for best mark adhesion.
