Chanchai Stainless produces and supplies Stainless Steel 440C Pipes in Bangkok, Thailand, recognized for their exceptional hardness, wear resistance, and strength. This martensitic stainless steel offers one of the highest carbon levels among stainless steels, ensuring excellent mechanical performance. These pipes resist corrosion in mild environments while retaining impressive strength. Stainless Steel 440C is ideal where hardness and toughness matter, making it suitable for high-performance industrial and mechanical applications. Chanchai Stainless focuses on precision manufacturing, ensuring these pipes are dependable for industries that need robust, long-lasting, and efficient piping solutions.
Stainless Steel 440C pipes contain a high carbon content (0.95–1.2%), chromium (16–18%), and small amounts of manganese, silicon, and molybdenum. This composition grants them outstanding hardness, reaching up to 60 HRC when heat-treated, making them one of the hardest stainless steels. Their tensile strength is around 760 MPa and yield strength is roughly 450 MPa. While toughness decreases compared to other stainless grades, they still have adequate ductility. The alloy offers moderate corrosion resistance, which can improve with polishing. These properties make 440C suitable for applications that require exceptional wear resistance, high hardness, and strength.
