What is Q235 steel plate made of?
Q235 is ordinary carbon structural steel with a yield strength ≥235MPa and a carbon content ≤0.22%. It has good plasticity and weldability, low cost, and is a general-purpose industrial steel.
Can Q235 steel plate be used for human implants?
Absolutely not. Q235 has no biocompatibility and will corrode and release heavy metals in the body, causing rejection, infection, and tissue damage. Its use in implants is strictly prohibited.
What is the core role of Q235 steel plate in the medical field?
It is used for non-contact structural components of medical equipment, such as equipment shells, frames, supports, guardrails, and medical furniture frames.
What is the core difference between Q235 steel plate and medical-grade stainless steel (304/316L)?
Q235: Low cost, moderate strength, not corrosion-resistant, no biocompatibility, only used for external structures.
304/316L: Corrosion-resistant, good biocompatibility, can be used for internal cavities of equipment, contact parts, and implant base materials. What are the basic requirements for Q235 steel plates in medical settings?
They must meet requirements for strength, rigidity, weldability, surface treatment (rust prevention/antibacterial), and must not come into direct contact with pharmaceuticals or bodily fluids.
