Self-Locking Wire Thread Inserts - High Strength Solutions from China Suppliers and Factory
Locking wire thread inserts require extremely high elasticity, strength, and fatigue resistance, resulting in a very specific material selection:
Cr-Ni stainless steel
The absolute mainstream and preferred material.
1Cr18Ni9 (304 / A2)
The most commonly used, offering excellent corrosion resistance, strength, and elasticity, suitable for most working conditions.
00Cr17Ni14Mo2 (316 / A4)
Molybdenum alloyed, with higher resistance to chemical corrosion and pitting, suitable for harsher environments such as marine and chemical industries.
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
What are the key material requirements for locking wire thread inserts?
Locking wire thread inserts require materials that offer extremely high elasticity, strength, and fatigue resistance to ensure reliable performance under stress.
Which material is the absolute mainstream choice for wire thread inserts?
Cr-Ni stainless steel is the absolute mainstream and preferred material selection for manufacturing locking wire thread inserts.
Why is 1Cr18Ni9 (304 / A2) stainless steel so widely used?
1Cr18Ni9 (304 / A2) is the most commonly used material because it offers excellent corrosion resistance, strength, and elasticity, making it highly suitable for most standard working conditions.
When should I choose 00Cr17Ni14Mo2 (316 / A4) over standard 304 stainless steel?
You should choose 00Cr17Ni14Mo2 (316 / A4) for harsher environments, such as marine and chemical industries, because it is molybdenum-alloyed and provides higher resistance to chemical corrosion and pitting.
What materials are used for wire thread inserts in extreme high-temperature environments?
High-temperature alloys, such as Inconel X 750, are used in extreme high-temperature applications like aircraft engines, though they are usually not provided as standard sets.
