Tool steel is specialized in the manufacture of a variety of customized gas springs and vibration isolators or similar characteristics of the construction of the key raw materials.

(1) High ductility limit oe and high ductility ratio os/ob to ensure excellent ductility characteristics, i.e. absorbing a lot of ductility without causing plastic deformation;

(2) High fatigue strength, fatigue is one of the most key destruction modes of customized composite elastic yellow, fatigue characteristics in addition to the composition and structure of steel, but also key by steel metallurgical industry quality (such as non-metallic materials) and elastic yellow process performance (such as carburizing) harm;

(2) Sufficient plastic deformation and ductility to avoid impact fracture;

(4) Other characteristics, such as excellent heat treatment process and plastic deformation production and processing characteristics, unique standards under the working temperature or corrosion resistance provisions.

2. Composition characteristics The composition and efficacy of carbon and aluminum alloy in steel are:

1) Medium and high carbon steel generally, carbon tool steel wc=0.6%~0.9%, aluminum alloy tool steel wc=0.45%~0.70%, after heat treatment and medium temperature quenching to obtain quenching trochtenite mechanism, can ensure the characteristics of the single spring.

2) The main use of aluminum alloy alloy tool steel is generally high alloy steel. Customized special-shaped spring main additives for Si, Mn, Cr, etc., its key effect is to improve the cutting performance, strengthen the conventional solution and improve the quenching reliability; Auxiliary additives for Mo, W, V and other strong carburizing elements, the key effect is to avoid carburizing defects from S], Mng caused by overtemperature shortcomings and improve quenching reliability and temperature resistance.

Detergent A into a coarse wear-resistant material, spring stiffness, elastic yellow vibration light decoration machine or hexagonal barrel (elastic yellow and coarse wear-resistant material volume ratio of 1:3, the use of detergent for elastic yellow net weight of 1%-2%) grinding and polishing after cleaning with cold water, elastic yellow surface scratches are gone, improve the smooth surface of elastic yellow.
