Yaman Steel has built a solid reputation as a reliable manufacturer and supplier based in Mumbai, India, specializing in high-quality Stainless Steel 420 Pipes. These pipes are perfect for applications that demand strength, hardness, and a bit of corrosion resistance. Crafted with cutting-edge processes and rigorous quality checks, they’re designed to perform reliably even in tough conditions. Yaman Steel offers these pipes in a variety of sizes, schedules, and finishes, all adhering to international standards. With a strong commitment to quality, durability, and prompt delivery, the company caters to a wide range of industries both locally and globally.
Stainless Steel 420 Pipes are made from martensitic stainless steel alloys, featuring about 12–14% chromium and a higher carbon content than grade 410. This unique blend allows for heat treatment, enhancing their hardness and strength. On the mechanical side, these pipes boast impressive tensile strength, excellent hardness, good wear resistance, and decent toughness when properly heat-treated. They also provide moderate corrosion resistance, maintaining their structural integrity in mildly corrosive environments.
