How does Q235 perform in the manufacture of medical devices?
Excellent weldability. Its low carbon equivalent reduces the likelihood of cracking during welding, making it suitable for welding and assembling medical device frames and supports. Grade B and above are more suitable for welded medical structures.
What advantages does Q235's plasticity offer for medical device processing?
With an elongation at break ≥26%, it can be cold-bent and stamped to create complex structural components for medical devices (such as trolley frames and equipment shells), reducing processing difficulty.
Does Q235 meet corrosion resistance standards in medical environments?
General corrosion resistance. Medical environments (including disinfectants and moisture) are prone to rusting, requiring surface treatment (galvanizing, painting, passivation) before use.
Are there quality grade requirements for Q235 used in medical devices?
Yes, Grade B and above are preferred; Grade D (meets impact toughness standards at -20℃) is selected for low-temperature environments (such as cold chain medical equipment); Grade A is prohibited for welded structures.
Is the hardness of Q235 suitable for medical device structural components? With a hardness of 120-160 HBW, it is moderate, ensuring structural strength while facilitating secondary processing such as drilling, cutting, and grinding, making it suitable for the manufacture of medical equipment parts.
