DT6 electric iron electric iron DT4A imported electromagnetic iron bar strip electric iron. It is an iron content of more than 99.5% of high-quality steel. Is a low carbon sulfur phosphorus iron. 1> It is mainly for electromagnetic relays, iron with iron, soft iron, magnetic clutch with iron, electronic locks with iron, automotive piston with electric iron, iron with magnetic shielding, aerospace instrumentation, military iron, galvanized iron pot with a plate, iron plate with electronic components, solenoid valves, magnetic separator with iron, no hairline iron, iron electron tubes, easy turning electric iron 2> base the main features: 1) good electromagnetic properties. The coercive force (Hc) of low magnetic permeability μ is high, the saturation magnetic induction (Bs) of high magnetic stability nor the magnetic aging. 2) high purity steel. Electromagnetic iron series of steel are killed steel, has adopted the refined, so the internal organization of dense, uniform, fine, less gas content, finished carbon content ≤0.004%, which created conditions for reliable parts users to simplify and shorten the annealing process . 3) Cold, thermal processing performance. Cold, such as cars, pier, red, bend, pull ...... so no problem. Thermal processing, such as re-forging, re-rolling process, crisp red sensitivity is small, many grades no red brittle zone, to ensure processing in a wide temperature range. 4) good surface quality. Good welding and plating performance. 5) high dimensional accuracy. Provides ultra-precision cold-rolled sheet, such as the thickness ≤105mm, thickness tolerance can ensure ≤0.03mm; thickness> 1.5mm, thickness tolerance can ensure ≤ ± 0.05mm.
