Stainless Steel 201 is an austenitic stainless steel that contains chromium, nickel, and manganese, featuring a lower nickel content compared to 304, which makes it a budget-friendly choice. Its typical makeup includes 16–18% chromium, 3.5–5.5% nickel, and 5.5–7.5% manganese. This grade offers solid resistance to corrosion and oxidation in moderately aggressive environments. SS 201 Pipes have a tensile strength of about 520 MPa and a yield strength of roughly 275 MPa, along with good ductility and hardness. These pipes are ideal for forming, welding, and machining processes, making them popular in applications where high strength and cost-effectiveness are prioritized over extreme corrosion resistance.

Stainless Steel 201 Pipes are an austenitic stainless steel grade primarily made up of chromium (16–18%), nickel (3.5–5.5%), and a higher manganese content (5.5–7.5%) compared to 304 stainless steel. It also features low carbon (≤0.15%) and small amounts of silicon, sulfur, and phosphorus. In terms of mechanical properties, it offers good tensile and yield strength, moderate ductility, and corrosion resistance in mildly corrosive environments. While it has a lower nickel content for cost-effectiveness, Stainless Steel 201 Pipes still boast excellent weldability and formability, making them suitable for structural, sanitary, and general-purpose uses.
Blundell Pipes and Tubes, one of the largest suppliers of Stainless Steel 201 Pipes in Hamilton, New Zealand, offers a comprehensive range of high-quality pipes and tubes suitable for various industrial applications. Their extensive inventory and commitment to exceptional service make them a go-to choice for stainless steel products in the region.
