Khaled Stainless, located in Cairo, Egypt, is a trusted manufacturer and supplier of Stainless Steel 436 nuts, designed for industrial applications that require resistance to corrosion and high temperatures. These nuts are crafted from ferritic stainless steel, featuring controlled chemistry and precision machining, which ensures they deliver consistent quality, accurate dimensions, and a long lifespan. Khaled Stainless provides SS 436 nuts to various sectors, including automotive, exhaust systems, heat exchangers, power generation, and general industry, both within Egypt and for export. By adhering to ASTM and EN standards and offering customization in size and threading, they guarantee reliable fastening solutions for even the most demanding conditions.
Stainless Steel 436 is a ferritic stainless steel that contains around 16–18% chromium, along with a touch of molybdenum to boost its resistance to corrosion and pitting. This unique composition not only enhances oxidation resistance but also improves performance compared to standard ferritic grades. SS 436 nuts have moderate tensile strength, good thermal stability, and low thermal expansion, which helps prevent loosening when temperatures fluctuate. They are magnetic and resistant to stress corrosion cracking. While their ductility and toughness may not match those of austenitic grades, they still maintain reliable mechanical stability for industrial applications.

Stainless Steel 436 nuts are ideal for situations where you need corrosion resistance and thermal performance without the higher costs associated with nickel-based alloys. You’ll commonly find them in exhaust systems, heat exchangers, boilers, furnaces, flue gas equipment, automotive parts, and power plant assemblies. They work well in industrial machinery that operates in oxidizing or mildly corrosive environments. However, it’s worth noting that SS 436 nuts aren’t suitable for marine or highly acidic conditions, but they excel in cost-effective thermal and industrial fastening applications.
