What is ISO 9154 – Nickel alloy bolts for aerospace about?  
Aerospace components are exposed to extreme conditions. Materials used for aerospace components need to have the ability to withstand extreme temperatures without damage. Nickel-based alloys are known for their excellent corrosion resistance and strength. They are suitable for high-temperature environments due to their superior heat resistance. 
ISO 9154 specifies the characteristics and quality assurance requirements for MJ threads bolts made of heat-resisting nickel-base alloy, of strength class 1 550 MPa, for aerospace construction.
ISO 9154 is applicable whenever it is referenced in a definition document.
Who is ISO 9154 - Nickel alloy bolts for aerospace for?  
ISO 9154 on nickel alloy bolts for aerospace is useful for: 
- Manufacturers and suppliers of bolts for aerospace applications
- Product design engineers 
- Quality control personnel 
- Aviation, Aerospace and Defence Industries 
Why should you use ISO 9154:2019 - Nickel alloy bolts for aerospace?  
Bolts are used in aircraft construction in areas where high strength is needed. MJ threads are ‘Metric threads for Aerospace’ used in aircraft, rockets, and space stations. ISO 9154 aids in the selection and testing of bolts with MJ threads and provides procurement specifications. 
ISO 9154 provides a clear description of aerospace bolts that can hold up to a specific strain and heat level, depending on its type. 
ISO 9154 helps you to understand and follow best practices for aerospace nickel alloy bolts, which contributes towards the maintenance of your quality management system.
Using ISO 9154 guidelines, you contribute towards safer flights and expeditions as well as longevity for the carrier.
