    Heat Treatment

    Vacuum Heat Treatment Furnace Imported Japan

    Resume:
    The vacuum quenching furnace adopts anoxic treatment, has no carburization and decarburization, and uses vacuum, being safe and pollution-free. It is computer-controlled, has uniform structure and hardness as well as good repeatability, and can meet the heat treatment requirements for all kinds of steel. The greatest feature of the furnace is that it can automatically run and continuously treat without moving the treated object from the beginning of quenching to the end of tempering.

    Gas Quenching Furnace Manufactured by NACHI

    Resume:
    The gas quenching furnace adopts anoxic treatment, has no carburization and decarburization, and uses neutral gas, being safe and pollution-free. It is computer-controlled, has uniform structure and hardness as well as good repeatability, and can meet the quenching requirements for all kinds of steel.

    Tempering Furnace Manufactured by NACHI

    Resume:
    The tempering furnace is suitable for all kinds of quenched steel. The reflector plate is arranged in the furnace to make rectification and wind speed uniform and prevent the influence of radiation, the temperature distribution is uniform in the furnace, and the furnace is computer-controlled and has uniform structure and hardness as well as good repeatability.

    Quality Characteristics of Heat-treated Product

    The quenching and tempering furnaces of the company can conduct heat treatment for various kinds of steel. Taking high-speed steel (W6Mo5Cr4V2) as an example, the quality characteristics of the quenched and tempered product are shown in the following figure:

    Quenching

    The hardness is more than HRC64.

    Tempering

    The hardness is between HRC61~65.

    Nitriding

    Multinite Furnace Manufactured by TECHNO

    Resume:
    NM gases (H2S, etc.) make the surface of the product activated before nitrification and make the sulfide diffused on the surface of the product while nitriding. The initial adaptability and friction properties (through solid lubrication) are improved by the formation of sulfur compounds (sulfide) at the outermost surface of the product. The furnace is computer-controlled, and has uniform structure, hardness and nitriding layer as well as good repeatability.

    Features and Advantages of Multinite

    The raw materials for Multinite include N2, NH3 and NM gas, the nitriding temperature is 400-620℃, and the treatment time is 3-5 hours.
    Multinite has the following advantages: good abrasion resistance, ablation resistance, occluding resistance, fatigue strength, corrosion resistance and vibration control.

    Evaluation of product section (SKH51 + high-temperature Multinite)

    Depth of Nitride Layer

    Position Compound Layer Diffusion Layer
    Value(μm) 12.0 140.0

    Section Hardness(HMv-100g)

    Section Depth (μm) Surface 20 30 40 50 60 70 80 Core
    Hardness(HMv) 1255 1213 1205 1170 1143 1136 1120 1099 771

    Result:

    ①The thickness of the compound layer is about 12 μm, which is more than predicted thickness (SUS).

    ②Depth: surface layer to 80μm, Hardness: 1,000HMv.

    Detecting Instrument

    The company has a full set of imported testing equipment for quality confirmation after heat treatment, including Surface Mirror Polishing Machine, Metal Microscope, Rockwell Hardness Tester, Vickers Hardness Tester (the photos are shown as follows), etc., having complete testing means.The structure can be clearly observed, and the surface hardness of the product can be accurately measured.
