We have years of experience in the field and are experts in creating robust, precisely designed flanges for a range of industrial uses, such as the petrochemical, power generation, and oil and gas industries. We are a reputable brand in the Middle East market thanks to our dedication to quality, prompt delivery, and client satisfaction. Jinay Metals guarantees that each AISI 4140 flange is expertly crafted to provide exceptional strength, resistance to corrosion, and dependable performance.
AISI 4140 flanges are made from a chromium-molybdenum alloy steel known for its excellent strength, toughness, and wear resistance. The typical chemical composition includes Carbon (0.38–0.43%), Chromium (0.8–1.1%), Molybdenum (0.15–0.25%), Manganese (0.75–1.0%), and Silicon (0.15–0.30%). Mechanically, AISI 4140 offers a tensile strength of 655–1080 MPa, yield strength of 415–930 MPa, and elongation of 20%. It maintains high hardness and impact resistance, making it ideal for heavy-duty applications where strength and fatigue resistance are crucial, such as flanges in high-pressure systems.
