Andre Stainless is a trusted name in the manufacturing and supply of Stainless Steel 420 Pipes in Pulau Ujong, Singapore. They specialize in providing high-strength, wear-resistant piping solutions that are perfect for tough industrial and mechanical applications. With a solid reputation for their expertise in high-carbon martensitic stainless steels, Andre Stainless crafts SS 420 pipes that boast impressive hardness, decent corrosion resistance, and outstanding mechanical performance. These pipes are meticulously engineered under rigorous quality control standards, catering to vital sectors like manufacturing, food processing, medical devices, and petrochemicals, where strength and durability are non-negotiable.
Stainless Steel 420 Pipes are made from a martensitic stainless steel alloy that contains about 12–14% chromium and at least 0.15% carbon. This unique blend allows the pipes to undergo heat treatment for exceptional hardness (up to 50 HRC) while still offering reasonable corrosion resistance in mild atmospheric and clean industrial settings. The tensile strength of SS 420 pipes generally falls between 700 to 850 MPa, depending on the heat treatment process, and they provide solid resistance to wear, fatigue, and impact.
