The thickness limit depends on the diameter: small diameter tubes with thick walls are harder to bend than thin-walled tubes of the same outer diameter. For S235 structural steel tubes, check the capacity table in the manual. For stainless steel, the MR 250 F manual is not suitable — request the HRB hydraulic version.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eHow can I avoid ovalization and creases during bending?\u003c\/summary\u003e\n\u003cp\u003eOvalization is reduced by using the correct diameter die that supports the tube externally, and by inserting an internal mandrel for thin-walled tubes (under 1.5 mm). A constant bending speed reduces irregularities compared to jerky movements. For tight radii (less than 1.5 × the tube diameter) ovalization is physiological — reducing it requires a specific internal mandrel.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eUp to what angle can it bend?\u003c\/summary\u003e\n\u003cp\u003eThe MR 250 F bends up to 180° in a single pass. For angles greater than 180° (spiral), it is necessary to flip the tube and continue bending with two passes. The integrated goniometric scale allows setting the exact angle, taking into account the material's typical springback.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eSpare parts and dies available?\u003c\/summary\u003e\n\u003cp\u003eOriginal spare parts available with 3–5 working day shipping.
