Markal 81922 Solid Paint Crayon Heat Treating Marker Red

Product Description

The MARKAL 81922 is a solid oil-base paint crayon designed for marking metal surfaces during annealing and heat-treating operations. The round-tip crayon lays down a bold red mark that remains legible on steel, iron, and aluminum through the thermal cycles common in metal fabrication and treatment processes. It is a single-unit marker with a compact form factor, weighing approximately 0.009 pounds, making it easy to keep on a workbench or in a tool pouch. Fabricators, welders, and heat-treat technicians use this crayon to mark parts before and during high-temperature processing where standard markers or ink-based markers would fail or burn off prematurely.

This crayon is suited for industrial and fabrication shop environments where metal components require clear identification through annealing, case hardening, or other heat-treating procedures. It works directly on steel, iron, and aluminum surfaces without surface prep. The oil-base formula is intended for use on bare metal in high-heat marking applications, making it a standard consumable in metalworking and manufacturing facilities.

Key Features

• Oil-base solid paint formula rated for annealing and heat-treating applications
• Round tip delivers consistent, visible marks on metal surfaces
• Red color family provides high contrast on steel, iron, and aluminum
• Compact single-unit crayon format fits easily in a tool pouch or bench drawer
• No cap or ink reservoir to dry out — solid paint construction for reliable use

Compatibility

Designed for use on steel, iron, and aluminum surfaces in annealing and heat-treating applications.

Installation Notes

This product is a marking consumable used by fabricators, welders, and heat-treat technicians. Apply marks directly to clean or mill-scale metal surfaces prior to or during thermal processing. Keep away from open flame when not in use. Store in a cool, dry location to maintain marking consistency.
