Stainless Steel 202 Instrumentation Tubes are high-performance tubing solutions designed for accurate and reliable performance in instrumentation and control systems. They are made from SS 202, an austenitic chromium-nickel-manganese alloy known for its good mechanical strength, formability, and cost-effectiveness. These tubes are widely used across various industries where corrosion resistance and dimensional accuracy are essential.
SS 202 is composed primarily of chromium (17–19%), nickel (4–6%), and manganese (7.5–10%). This composition gives it good corrosion resistance in mild environments, while also providing strength and toughness. Compared to SS 304, 202 offers a more economical solution, especially in non-severe corrosive conditions.
202 Instrumentation Tubes are manufactured to tight dimensional tolerances, which ensures precise flow control in sensitive applications. The smooth internal and external finishes help reduce friction, minimize pressure drops, and support laminar flow of fluids and gases. These properties are essential in applications where accuracy is critical.
While not as corrosion-resistant as 316 or 304 stainless steel in highly aggressive environments, SS 202 performs well in many general industrial and urban atmospheres. It is particularly suitable for indoor applications, mild chemical exposures, and clean environments where cost considerations are important.
