Irfan Pipes and Tubes, based in Istanbul, Turkey, has built a solid reputation as a reliable manufacturer and supplier of top-notch Stainless Steel 420 Pipes. These pipes are specifically designed for applications that demand high hardness, decent corrosion resistance, and long-lasting durability. The 420 grade is a martensitic stainless steel known for its impressive mechanical strength and wear resistance. Crafted with precision and in line with international standards, these pipes boast consistent dimensions, smooth surfaces, and dependable performance. They’re perfect for industrial, tooling, chemical, and structural applications where hardness, strength, and corrosion resistance are essential for enduring service in moderately aggressive environments.
Stainless Steel 420 Pipes mainly consist of iron, along with 12–14% chromium, 0.15–0.4% carbon, and trace amounts of manganese and silicon. Thanks to their martensitic structure, they deliver outstanding hardness, tensile strength, and wear resistance. These pipes provide moderate corrosion resistance in both atmospheric and mildly corrosive settings, while also maintaining good dimensional stability under mechanical stress. They demonstrate solid toughness, ductility, and fatigue resistance. 420 pipes are ideal for situations where mechanical strength and wear resistance are crucial, especially when corrosion exposure is limited or managed, making them a dependable choice for industrial, tooling, and structural applications.
