With a strong focus on excellence, innovation, and customer satisfaction, Chanchai Stainless guarantees that each product adheres to international standards for durability and performance. Our Stainless Steel 309 Pipes are crafted to endure high temperatures and corrosive conditions, making them a reliable choice for industrial applications. As a well-regarded supplier in Thailand, we deliver precision-engineered pipes that meet the diverse needs of various industries, ensuring lasting strength, quality, and cost-effective solutions.
Stainless Steel 309 Pipes are mainly made up of chromium (22–24%) and nickel (12–15%), which provide exceptional resistance to oxidation and heat. They also include controlled amounts of carbon, manganese, silicon, phosphorus, and sulfur, which enhance their mechanical and corrosion-resistant characteristics. With a tensile strength of about 620 MPa and a yield strength of roughly 310 MPa, these pipes demonstrate remarkable toughness and durability, even at high temperatures. Their density is 7.9 g/cm³, and they offer good elongation, making them perfect for challenging environments where strength, stability, and high-temperature resistance are crucial.
