Which material is most commonly used for trays and trolleys?

• A. Martensitic
• B. Austenitic
• C. Titanium
• D. Carbon steel

Answer: (B)

Trays and trolleys must withstand frequent cleaning, chemical disinfectants, and autoclaving, so the material needs excellent corrosion resistance and the ability to maintain a smooth, sanitary surface after repeated sterilization. Austenitic stainless steel fits these needs best: it resists rust and pitting, cleans easily, and preserves a clean finish through numerous heat cycles without warping or degrading. Its non-magnetic nature and good formability also help in manufacturing smooth-edged trays that are easy to decontaminate. In contrast, martensitic stainless steels, while harder, offer poorer corrosion resistance for regular hospital cleaning; carbon steel is prone to rust unless a coating is applied, and coatings can wear through; titanium, though highly resistant to corrosion, is expensive and not as practical for mass-produced trays and trolleys.
