Stainless Steel (316L): Best all-around, good corrosion resistance, moderate cost, 300-1000m depth. Titanium: Premium choice, excellent corrosion resistance, lightweight, high strength, 1000-3000m+ depth, 2-3x cost. Engineering Plastic (POM): Budget option, good for shallow water, 100-300m depth, lowest cost. For seawater ROV\/AUV, stainless steel recommended. For deep sea or aggressive environments, titanium worth the investment.<\/p>\n\n\n\n
