Pure iron DT4 material can be divided into four grades A/E/C according to the grade. What are the differences? How to choose?

Taiyuan City Yaoqiang Pure Iron Co., Ltd. (Electromagnetic Pure Iron/Electrical Pure Iron/Industrial Pure Iron) Introduction:

(1) Yaoqiang Pure Iron Grades: (DT3 DT4DT4A, DT4E, DT4CDT8, DT9)

(2) Yaoqiang Pure Iron Forms: Pure Iron Medium Plate, Pure Iron Round Steel, Pure Iron Coil Rod, Pure Iron Cold-Rolled Sheet, Pure Iron Coil, Pure Iron Sheet Slitting, Yaoqiang Pure Iron, Pure Iron Tube, Pure Iron Slab, Pure Iron Forging Material,

(3) Yaoqiang Pure Iron Uses: Used in Electrical Appliances, Telecommunications, Instruments and Various Magnetic Components, Electromagnetic Elements, such as: Relay Pure Iron, Electromagnetic Valve Pure Iron, Electromagnetic Lock Pure Iron, Alloy Electromagnetic Pure Iron, Pure Iron Medium and Heavy Plate for Galvanizing Pot, Yaoqiang Pure Iron, Magnetic Separator Pure Iron, Pure Iron for Iron Remover, Pure Iron for Sensors, Pure Iron, Pure Iron for Electromagnetic Clutch, Pure Iron for Elevator Brakes, Pure Iron for Claw Pole, Various types of relay cores, armature yokes in electrical appliances and telecommunications; Core material for strong electromagnets; Yaoqiang Pure Iron; Magnetic components for instruments and meters; DC motor cores and housings; Electrical or magnetic parts for automobiles, tractors, and lathes; Brakes, clutches. Magnetic shielding equipment, such as various magnetic shielding covers or shielding boxes, requiring high shielding equipment. Sealing materials, etc.

(4) Yaoqiang Pure Iron Performance:

1) Good electromagnetic performance. Low coercivity (Hc), high permeability μ, high saturation magnetic induction (Bs), stable magnetism and no magnetic aging.

2) High steel purity. Yaoqiang electromagnetic pure iron series steels are all killed steels, and through refining, the internal structure is dense, uniform, good, with low gas content, finished product carbon content ≤0.004%, providing reliable conditions for simplifying and shortening the annealing process of parts for users.

3) Good cold and hot working performance. Cold working such as turning, upsetting, punching, bending, drawing, etc., all present no problems. Hot working, such as re-forging and re-rolling, has low red brittleness sensitivity, many grades have no red brittleness zone, allowing processing within a wide temperature range.

4) Good surface quality. Has good welding and electroplating performance.

5) High dimensional accuracy. Can provide precision cold-rolled sheets, for example, sheet thickness ≤1.5mm, thickness tolerance can be guaranteed ≤0.03mm; sheet thickness >1.5mm, thickness tolerance can be guaranteed ≤±0.05mm.
