ASTM G67 (NAMLT) | Intergranular Corrosion (IGC) | Check weight loss in acid bath. |
ASTM G129 (SSRT) | Stress Corrosion Cracking (SCC) | Pull metal slow in bad air. |
The ASTM G66 test uses hot chemical water. Metal sits for 24 full hours. Workers check pictures to grade rust resistance.
Metal tempers boost overall rust control.
H116 Temper: Cold rolling steps make metal hard. It stops tiny inner metal rust.
H321 Temper: Gentle heat treats cold metal sheets. This heat spreads tiny particles evenly. It stops bad surface rust well.
The H321 heat step stops metal changes later. Metal stays safe for a long time. The H32 temper keeps upper decks strong. It brings great ocean rust protection.
Shipyards use aluminum for shipbuilding to build ships. Weld heat weakens metal near joints. Engineers call this soft spot the heat-affected zone. Builders use filler wires 5183, 5356, and 5556. They weld heavy plates with these wires. Filler metals fix joint strength on panels.
Fabrication Tip: Techs control heat to keep welds very strong.
Workers bend raw alloy sheets into curved panels. Lower magnesium in 5086 aluminum aids bending. This metal bends without tiny cracks at sea. So, curved boat hulls stay very tough.
Heat bends metal during every weld job. Techs clamp alloy plates with hydraulic tools. Special tools trim plate edges before welding. Good weld steps spread heat across structures. Thermal care keeps aluminum for shipbuilding straight.
