D2 carbon steel, this steel is very used by professional craftsmen to manufacture all kinds of knives.

 

Its main features:

-High resistance to wear.

-High edge retention.

-Low oxidation.

-Moderate toughness.

-Up to 64 HRC.

 

This is due to its high content in chrome.

 

Chemical composition (%):

C: 1.55, Si: 0.30, Mn: 0.30, Cr: 12, Mo: 0.75, V: 0.75

 

This steel is not recommended for beginners, its degree of difficulty of work is medium - high.

Annealed (soft), it is provided to facilitate the work, since tempered once is very difficult work.


Heat treatment:

- Forging : 850-1050 ° C. Preheat to 930 ° C for 10 to 20 minutes. Very slow furnace cooling or insulating materials (sand, salt, mica) forging not recommend unless experienced craftsmen. Cracks tend to suffer when working outside the range of temperature or cooled quickly.

- Normalizing : 650 to 700 º C. To eliminate the structural stresses caused by forging or stock removal. Recommended time 1 hour.

- Hardening ( oil ) : 1020-1050 ºC. Pre- heating at 815 - 850 °C, the temperature stabilized, thermal quenching temperature jump, ever, keep at least 1 minute per millimeter. Quenching in oil at 210-250 ° C to reduce thermal shock and to keep cooling for 15 to 30 minutes. Hardness of 58-62 HRC.

- Tempering : Slow heating to the tempering temperature (see temperature chart). Maintain the temperature reached 10 minutes per millimeter, the minimum recommended time is 1 hour.

It is recommended that the quenched and tempered in conservative atmosphere, see foil tempered.

This heat treatment is preferred. It can vary temperatures, times or embodiment thereof, depending on your needs or experience in the process.

Buen material a dureza óptima para mecanizado

Estoy muy satisfecho con la compra, la dureza del metal recocido favorece el corte y desbaste. Muy robusto. Compré la lámina de 1 metro con 5.5mm de espesor. Como indica la descripción no es perfectamente plano, hay una pequeña curvatura que no afecta a la rectitud de las piezas cortadas, sólo apreciable al observar la lámina entera.

J'aime vraiment cet acier pour fabriquer des couteaux, 5mm est parfait pour une survie de petite taille, sont plus résistants à frapper, couper, hacher.
Remarquable, la livraison rapide, est sorti le même jour.

Formato pequeño

Gracias por añadir un formato mas chico, para los que hacemos algun cuchillo de vez en cuando una barra entera es mucho, pero este miniformato tiene la medida justa.

Calidad y Precio

Llevaba tiempo con ganas de comprarlo, pero me parecia muy barato el precio para 1metro, pensaba que seria un acero de mala calidad o algo asi, porque este acero lo compraba en otro sitio y me cobraban casi lo mismo por 25cm. El acero es acojonante, de muy buena calidad, diria que hasta mejor que donde lo compraba.
