What are the processing techniques for Q235 stainless steel used in medical devices?
Cutting (flame/plasma/laser), cold bending, stamping, drilling, welding, and grinding. These processes are relatively easy and suitable for manufacturing small batches of diverse medical device components.
What precautions should be taken when welding Q235 stainless steel in the medical industry?
Select grade B or higher steel, control the welding temperature, and perform stress relief treatment after welding. Welded joints must undergo unseen testing (UT/ET) to ensure the structural safety of the medical device.
What are the surface treatment methods for Q235 medical components?
Hot-dip galvanizing (zinc layer ≥40μm), electrostatic spraying, and passivation treatment. The core functions are rust and corrosion prevention, suitable for contact with disinfectants in medical environments.
What are the testing standards for Q235 medical components?
Comply with GB/T 700-2006, testing chemical composition (S/P≤0.045%), mechanical properties (yield/tensile/elongation), surface defects (UT/ET), and hydrostatic testing (for pressure-bearing components). Q235 What are the post-molding processing requirements for medical components?
After molding, burrs must be removed and the surface polished to prevent scratches to medical staff or consumables; welded parts must have weld slag removed and be treated with rust prevention to ensure the appearance and safety of the equipment.
