A286 bolts belong to which material?
A286 material is also known as A286 stainless steel. It is a precipitation hardening alloy primarily composed of Fe, Ni, and Cr, with trace amounts of Ti, Mo, and V. This alloy offers excellent mechanical properties, high strength and exceptional corrosion resistance, especially in elevated temperature environments.
A286 bolts are manufactured by heating the material and then it is formed into a desirable shape. Reputed manufacturers offer different types of fasteners like A286 screws, threaded rods, bolts, studs, etc. to meet your needs.

Where can you install A286 bolts? What are the limitations and temperature range?
Looking to buy A286 stainless steel bolts for high temperature applications? Check corrosion resistance and other features
Bolts made of A256 material can be installed in applications where high strength, corrosion resistance and temperature resistance are required. Thus, they are found in industries like aerospace, automotive and other industrial applications.
Talking about the limitations and temperature range, here are a few things to consider:
- NAS A286 bolts can withstand elevated temperatures up to 704°C approximately. They also show good creep resistance and mechanical strength at high temperatures.
- A286 hex bolts might experience reduced toughness and embrittlement at temperatures below -196°C.
- A286 hex head bolts show excellent corrosion resistance, especially in oxidizing and mildly reducing environments. But, they might be unsuitable for highly corrosive or chloride-rich environments.
What is the corrosion resistance of A286 nuts and bolts?
Want to know how to increase A286 bolts strength? Compare A286 stainless steel bolts, nuts and screws from other stainless steel alloys
A286 nuts and bolts offer excellent corrosion resistance in various environments. They can withstand oxidizing, mildly reducing, sulphuric acid, chloride and alkaline conditions. Consider the specific A286 bolts strength in resisting corrosion and then choose it for your application. Factors like temperature, concentration and presence of other corrosive agents can affect the overall corrosion performance.
Are A286 fasteners magnetic?
A286 fasteners are generally magnetic. EN 1.4980 hex bolts are Fe based alloy that contains significant amounts of Fe, Ni, and Cr. The presence of Fe in the alloy makes them susceptible to magnetism.
When and why should you go for A286 bolts heat treatment?
Bolts made of A286 can undergo heat treatment for several reasons:
- Solution Annealing- to enhance their mechanical properties and remove any residual stresses.
- Age Hardening- to further enhance their strength and hardness of A286 socket head cap screws and bolts.
- Stress Relief- to reduce residual stresses arising from manufacturing processes or prior use.
