EN 10305-1 E195 is the lowest strength precision tube in the EN 10305-1 precision tube series, with a normalized yield strength of 195 MPa and a carbon content of a maximum of 0.06%. E195 tubes are cold-drawn to close OD and wall thickness tolerances, providing consistent dimensions and tight tolerances in light-duty hydraulic lines, automotive sub-frames, and other general mechanical assemblies that will require forming, bending or flaring after delivery. E195 is supplied in +A (annealed) or +N (normalized) condition to ensure maximum ductility for tubes that require processing at the customer's facility to achieve minimum springback and consistent weld quality with no preheat required. These tubes are usually found in automobiles, industrial equipment, furniture, material-moving machinery and engineering systems where they are required for strength, durability, and resistance to wear under severe operating conditions. We at usapipingsolution provide Mechanical Steel Tubes according to the ASTM A513 standard in a variety of sizes and specifications to fulfill various industrial uses and international quality standards.
