6-14 A286 Inconel Petrochemical Shoulder Bolt High Temperature High load-bearing capacity
1,Description:
Shoulder screws are also referred to as shaft shoulder screws, stop screws, stop bolts, brake bolts, equal-height screws, among other names. The shoulder screw works together with the bolt pull rod and serves primarily as a mold component to regulate the opening stroke between the fixed mold base plate, the runner stripper plate, and the stationary mold plate in three-plate molds.
Since it can be positioned on the mold parting surface, the mold design can be made more compact. This product type exhibits elevated hardness, superior toughness, outstanding abrasion resistance, and thermal stability. It is well-suited for high-precision molds and can substantially prolong their service life. In particular, the thermal expansion of precision molds is effectively managed, rendering it appropriate for molds operating in elevated-temperature conditions. Its specification follows ISO 7379. The material for the 12.9 grade plug screw is SCM435 alloy steel, with a comprehensive hardness of HRC40°.
The shoulder screw operates in combination with the bolt pull rod and functions chiefly as a mold accessory to govern the opening distance between the fixed mold seat plate, the sprue ejector plate, and the fixed mold template in three-plate mold configurations.
Owing to its ability to be mounted on the mold parting surface, the mold architecture can be downsized. This category of product demonstrates high rigidity and ductility, coupled with excellent wear endurance and heat tolerance. It is appropriate for precision tooling and contributes to extending their operational lifespan, notably exerting a certain influence on managing the thermal distortion of precision molds. It is applicable to tooling utilized in high-temperature working settings.
2,Applications:
Screws are widely used in the industrial field. From large items like spaceships and aircraft to small ones like mobile phones and tables and chairs, they are indispensable. Therefore, they are also known as the "rice of industry".
How important is that tiny screw to an aircraft? According to the data, the Boeing 747There are approximately over 6 million parts in the series of aircraft, and among these parts, fastenersThe proportion accounts for half.There are also quite a few flight safety accidents caused by screw problemsIf experts analyze that one of the reasons for the emergency landing of Sichuan Airlines Flight 3U8633 is very likely to be that the screws of the windshield were substandard or excessive force was applied during installation, which led to cracks in the windshield. It finally falls off.
A286 bolts have obvious advantages over bolts made of other materials: 4.1 High strength: Its high strength characteristic enables it to perform better under heavy loads or high pressure, reducing the risk of equipment failure caused by bolt fracture. 4.2 High-temperature resistance: It can maintain excellent mechanical properties in high-temperature environments and is suitable for high-temperature applications in industries such as aviation and petroleum. 4.3 Corrosion resistance: Its excellent corrosion resistance makes it less prone to corrosion when used in harsh environments such as chemical engineering and Marine environments, thereby extending the service life of the equipment.
3,Technical Advantages
A286 is a nickel-based superalloy with Fe-25Ni-15Cr as the matrix, featuring high high-temperature strength, resistance to high-temperature oxidation and excellent processing performance.
Chemical composition and strengthening elements
A286 (Incoloy A-286) is A precipitation-hardening superalloy based on Fe-Ni-Cr. Its main components and functions are as follows:
• Iron (Fe) : A matrix element, accounting for approximately 55%, providing structural support.
• Nickel (Ni) : approximately 25%, enhancing high-temperature strength and corrosion resistance.
• Chromium (Cr) : Approximately 15%, enhancing oxidation resistance and corrosion resistance.
• Titanium (Ti) : approximately 2%, used for age hardening.
• Aluminum (Al) : approximately 0.2%, enhancing antioxidant performance.
Molybdenum (Mo) and vanadium (V) : Enhance high-temperature strength and creep strength.
• Trace amounts of boron (B) : Refine grains and enhance toughness.
• Carbon (C) : approximately 0.04%, controlling hardness and strength.
