Emilio Stainless stands out as a top-notch manufacturer and supplier located in Manila, Philippines, specializing in high-quality stainless steel products, including Stainless Steel 422 Nuts. With years of experience under their belt and a strong dedication to excellence, this company delivers durable and precision-engineered fastening solutions that adhere to international standards. Emilio Stainless has built a reputation for reliability, technical know-how, and a customer-centric approach. Their Stainless Steel 422 Nuts are highly regarded for their impressive strength, resistance to corrosion, and ability to withstand heat, making them perfect for tough environments where performance, safety, and longevity are crucial.
These Stainless Steel 422 Nuts are crafted from a martensitic stainless steel alloy primarily made up of iron, chromium (12–14%), molybdenum, and trace amounts of carbon, manganese, silicon, and nickel. This unique blend offers remarkable mechanical strength, hardness, and oxidation resistance. The material boasts a tensile strength between 620–850 MPa, along with solid creep and fatigue resistance at higher temperatures. Plus, Stainless Steel 422 can be heat-treated to boost its hardness and wear resistance, making it a dependable choice for high-stress applications that require both strength and protection against corrosion.
