Akor Stainless is a leading manufacturer and supplier located in Abuja, Nigeria, known for crafting high-quality Stainless Steel 436 Nuts that offer outstanding durability and heat resistance. These nuts are specifically engineered for tough industrial and mechanical settings where strength, resistance to corrosion, and thermal stability are crucial. Made from ferritic stainless steel, SS 436 boasts better oxidation and scaling resistance than traditional grades. Akor Stainless guarantees precise threading, accurate dimensions, and a consistent finish across all their products. These nuts find their place in automotive exhaust systems, chemical plants, heat exchangers, and other high-temperature applications that demand reliable fastening performance.
Stainless Steel 436 Nuts generally consist of 16–18% chromium, 0.75–1.25% molybdenum, and a low carbon content (≤0.12%), along with stabilizers like titanium or niobium to enhance corrosion and heat resistance. This ferritic alloy excels in oxidation resistance and provides moderate protection against corrosion in high-temperature environments. The mechanical properties include a tensile strength of about 450–500 MPa, a yield strength of 275 MPa, and an elongation of roughly 22%. SS 436 retains magnetic properties, offers good thermal conductivity, and maintains strong dimensional stability, making it perfect for fasteners in heat-intensive applications.
