What is DT4E pure iron and why is it used for solenoid housings?
Answer
A solenoid valve housing usually carries one material line on the drawing, DC04 or DT4E, and that single line decides three things at once: how the valve behaves magnetically, how many drawing stages the part needs, and whether the finished housing has to be magnetic annealed. The two grades are not two versions of the same steel. One is a European cold-rolled deep drawing steel chosen for formability; the other is a Chinese electromagnetic pure iron chosen for soft magnetic performance, with a chemistry ceiling that exists to keep coercivity low.

What an engineer still needs from you
- material and material condition (grade, temper)
- material thickness, plus the key diameter, height and wall thickness
- tolerances, burr direction and the visual acceptance standard
- annual volume - it decides whether tooling is single-hit, progressive or transfer
- surface finish, and any secondary machining, annealing or plating
Next step. Send the drawing for a manufacturability review, or send the part data for a process and cost route.
