Quick guide: Freshwater = 304 or 316L stainless (both fine). Saltwater = 316L stainless minimum. Harsh saltwater (hot, polluted, high flow) = Duplex stainless or Titanium. Extreme depth\/weight critical = Titanium. Avoid aluminum in saltwater (corrodes quickly). Tell us your environment and we&#8217;ll recommend the right material. 316L stainless works for 90% of marine applications and is our standard offering.<\/p>\n<\/div>\n<h2>Material Selection Guide<\/h2>\n<h3>Quick Material Selector<\/h3>\n<table border=\"1\" cellpadding=\"8\">\n<tr>\n<th>Your Environment<\/th>\n<th>Minimum Material<\/th>\n<th>Recommended<\/th>\n<th>Premium Option<\/th>\n<\/tr>\n<tr>\n<td>Freshwater (lake, river)<\/td>\n<td>304 Stainless<\/td>\n<td>316L Stainless<\/td>\n<td>Titanium<\/td>\n<\/tr>\n<tr>\n<td>Brackish water (estuary)<\/td>\n<td>316L Stainless<\/td>\n<td>316L Stainless<\/td>\n<td>Duplex\/Titanium<\/td>\n<\/tr>\n<tr>\n<td>Saltwater (ocean, standard)<\/td>\n<td>316L Stainless<\/td>\n<td>316L Stainless<\/td>\n<td>Titanium<\/td>\n<\/tr>\n<tr>\n<td>Hot saltwater (>30\u00b0C)<\/td>\n<td>316L Stainless<\/td>\n<td>Duplex 2205<\/td>\n<td>Titanium Gr5<\/td>\n<\/tr>\n<tr>\n<td>Polluted water (harbor, industrial)<\/td>\n<td>316L Stainless<\/td>\n<td>Duplex 2205<\/td>\n<td>Titanium Gr5<\/td>\n<\/tr>\n<tr>\n<td>High flow\/turbulent water<\/td>\n<td>316L Stainless<\/td>\n<td>Duplex 2205<\/td>\n<td>Titanium Gr5<\/td>\n<\/tr>\n<tr>\n<td>Deep water (>2000m)<\/td>\n<td>316L Stainless<\/td>\n<td>High-strength stainless<\/td>\n<td>Titanium Gr5<\/td>\n<\/tr>\n<tr>\n<td>Weight critical (AUV, portable)<\/td>\n<td>316L Stainless<\/td>\n<td>Titanium Gr5<\/td>\n<td>Titanium Gr5<\/td>\n<\/tr>\n<\/table>\n<h3>Material Options Explained<\/h3>\n<h4>304 Stainless Steel<\/h4>\n<ul>\n<li><strong>\u0627\u0644\u0623\u0641\u0636\u0644 \u0644\u0640<\/strong> Freshwater, occasional saltwater exposure<\/li>\n<li><strong>Pros:<\/strong> Lowest cost, good general corrosion resistance<\/li>\n<li><strong>Cons:<\/strong> Not ideal for continuous saltwater immersion<\/li>\n<li><strong>\u0627\u0644\u062a\u0643\u0644\u0641\u0629:<\/strong> $ (baseline)<\/li>\n<li><strong>HYSF use:<\/strong> Freshwater applications only<\/li>\n<\/ul>\n<h4>316L Stainless Steel (Our Standard)<\/h4>\n<ul>\n<li><strong>\u0627\u0644\u0623\u0641\u0636\u0644 \u0644\u0640<\/strong> 90% of marine applications<\/li>\n<li><strong>Pros:<\/strong> Excellent saltwater resistance, good strength, reasonable cost<\/li>\n<li><strong>Cons:<\/strong> Can experience crevice corrosion in stagnant conditions<\/li>\n<li><strong>\u0627\u0644\u062a\u0643\u0644\u0641\u0629:<\/strong> $$ (20-30% more than 304)<\/li>\n<li><strong>HYSF use:<\/strong> Standard material for all saltwater connectors<\/li>\n<\/ul>\n<h4>Duplex 2205 Stainless<\/h4>\n<ul>\n<li><strong>\u0627\u0644\u0623\u0641\u0636\u0644 \u0644\u0640<\/strong> Harsh marine environments<\/li>\n<li><strong>Pros:<\/strong> 2x corrosion resistance vs 316L, higher strength<\/li>\n<li><strong>Cons:<\/strong> Higher cost, longer lead time<\/li>\n<li><strong>\u0627\u0644\u062a\u0643\u0644\u0641\u0629:<\/strong> $$$ (50-80% more than 316L)<\/li>\n<li><strong>HYSF use:<\/strong> Available for harsh environment applications<\/li>\n<\/ul>\n<h4>Titanium Grade 5 (Ti-6Al-4V)<\/h4>\n<ul>\n<li><strong>\u0627\u0644\u0623\u0641\u0636\u0644 \u0644\u0640<\/strong> Extreme conditions, weight-critical applications<\/li>\n<li><strong>Pros:<\/strong> Virtually immune to corrosion, 45% lighter than steel, very strong<\/li>\n<li><strong>Cons:<\/strong> Premium cost, longer lead time<\/li>\n<li><strong>\u0627\u0644\u062a\u0643\u0644\u0641\u0629:<\/strong> $$$$ (3-5x more than 316L)<\/li>\n<li><strong>HYSF use:<\/strong> Deep water, high-performance applications<\/li>\n<\/ul>\n<h4>Aluminum (Anodized)<\/h4>\n<ul>\n<li><strong>\u0627\u0644\u0623\u0641\u0636\u0644 \u0644\u0640<\/strong> Freshwater only, budget applications<\/li>\n<li><strong>Pros:<\/strong> Lightweight, low cost<\/li>\n<li><strong>Cons:<\/strong> Poor saltwater performance, galvanic corrosion risk<\/li>\n<li><strong>\u0627\u0644\u062a\u0643\u0644\u0641\u0629:<\/strong> $ (similar to 304)<\/li>\n<li><strong>HYSF use:<\/strong> Not recommended for marine use<\/li>\n<\/ul>\n<h3>Environment-Specific Recommendations<\/h3>\n<h4>Freshwater Applications<\/h4>\n<p><strong>Examples:<\/strong> Lakes, rivers, pools, tanks, freshwater aquaculture<\/p>\n<ul>\n<li><strong>Recommended:<\/strong> 316L stainless (standard)<\/li>\n<li><strong>Why:<\/strong> Good corrosion resistance, cost-effective<\/li>\n<li><strong>Avoid:<\/strong> Nothing specific, all materials work in freshwater<\/li>\n<\/ul>\n<h4>Coastal Saltwater<\/h4>\n<p><strong>Examples:<\/strong> Harbors, bays, coastal aquaculture, shallow ROV<\/p>\n<ul>\n<li><strong>Recommended:<\/strong> 316L stainless (standard)<\/li>\n<li><strong>Why:<\/strong> Proven performance in typical saltwater<\/li>\n<li><strong>Avoid:<\/strong> Aluminum, plain carbon steel<\/li>\n<\/ul>\n<h4>Open Ocean<\/h4>\n<p><strong>Examples:<\/strong> Offshore oil &#038;
