The common metals in life are relatively active in oxidation reaction, and once the reaction occurs, the original mechanical properties of the metal will be lost. In order to maintain the mechanical properties of the metal for a longer period of time, the metal surface is generally treated accordingly. Metal surface treatment technology uses chemical, electrochemical, physical, mechanical, and composite methods to form a structure on the metal surface that is different from the base material of the metal itself, so as to resist oxidation and corrosion in humid, high temperature, acid and other environments. Thereby extending the service life of the metal itself. However, the metal surface treatment does not change the properties of the metal itself. It just adds a special protective film on the metal surface, so that the metal after the surface treatment has different characteristics such as wear resistance, corrosion resistance, or high temperature resistance.

DISGO is a special metal surface treatment technology. Disco is completely environmentally friendly and complies with the EU ROHS (Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment). Disco has further developed a chromic acid-free ultra-thin film thick corrosion-resistant surface treatment technology for the phenomenon of hydrogen embrittlement caused by hot rust treatment. The products after Disco surface treatment avoid hydrogen embrittlement due to the protection of high-grade non-chromic acid.

Disco's metal surface treatment technology has the following characteristics:

1. High corrosion resistance-salt spray test reaches more than 2000 hours

2. No hydrogen embrittlement——————No pickling in the treatment process

3. Low temperature treatment————The low temperature treatment process of 200℃ will not cause material changes

4. Drug resistance——————Strongly resistant to acid rain

5. Heat resistance——————Heat resistance to 300℃

Jiaxing Hebang Machinery Technology adopts Japanese Disco surface treatment technology, and the processed fasteners are corrosion-resistant and high-temperature resistant.
