Q: What are the core material characteristics of Q235 steel?
A: It is a low-carbon structural steel with a yield strength ≥235MPa, good plasticity and toughness, excellent weldability, good processability and formability, low cost, and mechanical properties that meet general structural stress requirements.
Q: What are the core advantages of using Q235 steel in the medical industry?
A: High cost-effectiveness, easy processing and welding, good formability, meeting the structural strength requirements of non-core contact parts in the medical field, and procurement and processing costs are far lower than those of special steels such as stainless steel.
Q: What are the core principles for the application of Q235 steel in the medical industry?
A: It should not directly contact human tissue, blood, medications, or sterile treatment areas; it should only be used for non-contact parts such as structural support and frame load-bearing of medical equipment/facilities.
Q: What are the core differences between Q235 and the commonly used 304 stainless steel in medical applications?
A: Q235 is low-carbon steel, lacks corrosion resistance, and is inexpensive; 304 stainless steel contains chromium and nickel, is acid and alkali resistant, corrosion resistant, meets medical and health requirements, and is expensive. Their applications do not overlap.
Q: Which should be chosen in the medical industry: Q235A, Q235B, Q235C, or Q235D?
A: Q235B is the preferred choice. It has a moderate carbon content, impact toughness sufficient for room temperature use, stable weldability, and can adapt to the processing and stress requirements of medical equipment frames. Type A has poor toughness, and Types C/D are too expensive and unnecessary.
