    Product Details

    Locking wire thread inserts require extremely high elasticity, strength, and fatigue resistance, resulting in a very specific material selection:
    Cr-Ni stainless steel

    Cr-Ni stainless steel

    The absolute mainstream and preferred material.
    advantage-2
    1Cr18Ni9 (304 / A2)

    1Cr18Ni9 (304 / A2)

    The most commonly used, offering excellent corrosion resistance, strength, and elasticity, suitable for most working conditions.
    advantage-2
    00Cr17Ni14Mo2 (316 / A4)

    00Cr17Ni14Mo2 (316 / A4)

    Molybdenum alloyed, with higher resistance to chemical corrosion and pitting, suitable for harsher environments such as marine and chemical industries.
    advantage-2
    High-temperature alloys

    High-temperature alloys

    Such as Inconel X 750, used in extreme high-temperature environments (such as aircraft engines), but usually not provided as standard sets.

    Frequently Asked Questions

    Q: What materials are typically used for locking wire thread inserts?

    Locking wire thread inserts are mainly made of Cr-Ni stainless steels, including 1Cr18Ni9 (304 / A2) and 00Cr17Ni14Mo2 (316 / A4), as well as high-temperature alloys like Inconel X 750 for specialized applications.

    Q: Why is 304 (1Cr18Ni9) stainless steel the most commonly used material?

    304 (A2) stainless steel is the preferred standard material because it offers excellent corrosion resistance, high tensile strength, and superior elasticity, making it suitable for the majority of industrial working environments.

    Q: When should I choose 316 (00Cr17Ni14Mo2) stainless steel inserts?

    You should choose 316 (A4) stainless steel when your application is exposed to harsh environments, such as marine operations or chemical processing, due to its molybdenum alloy content which provides higher chemical corrosion and pitting resistance.

    Q: What are high-temperature alloy inserts like Inconel X 750 used for?

    High-temperature alloys like Inconel X 750 are designed for extreme thermal conditions, such as inside aircraft engines. Because of their specialized nature, they are typically not supplied in standard sets.

    Q: Why do locking wire thread inserts require highly specific materials?

    These inserts require materials with extremely high elasticity, strength, and fatigue resistance to maintain secure thread locking performance under vibration, thermal cycles, and mechanical stress.
