These steps ensure that 9260 spring steel maintains its resilience and ability to absorb shocks without failing.

T10 steel, with its high carbon and tungsten content, requires careful heat treatment to avoid brittleness. The process typically involves austenitizing, heating the steel to transform its microstructure to austenite, followed by quenching to form martensite and significantly increase hardness. Tempering is then carried out to achieve the desired balance between hardness and toughness.

Forging and Tempering

Forging and tempering are essential for shaping and enhancing the properties of both 9260 spring steel and T10 steel.

Forging involves heating 9260 spring steel to a high temperature and then hammering or pressing it into the desired shape, refining the grain structure and enhancing toughness and ductility. Post-forging, tempering is done to relieve stresses and adjust hardness, ensuring it can withstand heavy impacts without fracturing.

T10 steel is also heated and shaped through hammering or pressing. Due to its high hardness, careful control is necessary to prevent cracking during forging. Following forging, tempering is crucial to reduce brittleness and improve edge durability, allowing the steel to maintain a sharp edge without chipping.
