HC surface treatment network news: steel blackening agent is the use of workpiece tempering residual heat black, process environmental protection, energy saving, is a traditional alkaline blackening alternative. Steel blackening agent can be used for black cast iron, various carbon steel, alloy steel, and mechanical parts such as powder metallurgy.

It is used for rust and blackening of various mechanical parts such as carbon steel, cast iron, alloy steel, and powder metallurgy. Widely used in the blackening of various steel parts such as standard parts, fasteners, screws, nuts, chains, springs, spring pads, bicycle parts, auto parts, machine parts, hydraulic parts, engineering machinery parts, railway equipment.

    Product advantages:
    1. Water-soluble emulsion, environmentally friendly and safe;
    2. It is produced in line with the heat treatment mesh belt furnace, which is efficient and energy-saving;
    3. The processing process forms a continuous operation, so that the tempering is blacked out once;
    4. After the blackening, the workpiece has luster, corrosion resistance and strong rust resistance;
    5. Reduce labor intensity and improve production environment;
    6. Save energy, reduce costs and increase productivity;
    7, no need to pickling before blackening, no need to rinse after blackening, no three waste discharge;
    8. The workpiece has no hydrogen embrittlement pinholes and burrs after blackening;
    9. Completely replace traditional alkaline blackening and eliminate pollution;
    10, Jinhu brand blackening agent greatly reduces the processing cost of parts.
