For the Royal Australian Navy's (RAN) new Hobart-class destroyers that are expected to enter service by 2016, construction is in full swing. The lead ship, HMAS Hobart, is in the works, using an approximated 3,000 tons of steel. Two more ships, HMAS Brisbane and HMAS Sydney, are currently in the planning stage.
You most likely know that steel plus water resembles putting two sworn enemies to live under one roof. As if that isn't challenging enough, you'll be putting a piece of steel in saltwater that is popular for its corrosive properties. If the new ships will support the RAN's fleet, the steel made use of needs to be created to resist seawater corrosion for an extended period. The good news is, manufacturers can consider many ways to make steel solutions in Melbourne happen.
It isn't just the hull that needs security even as it needs the most security due to the fact that it touches the water all the time. The entire ship has to be shielded from any destructive particles during its voyage at sea. Rust in the vital structures is the last thing you want to take place.
Some maritime mishaps have blamed corrosion in the ship's framework for forcing it to snap like a twig. In 2002, the Greek oil tanker Prestige sank off the northwest coast of Spain as it split in two and polluted the water with 70,000 tons of fuel. Corrosion was discovered in the ballast areas of the tanker based upon an examination days after the accident.
Even when you're not in the shipbuilding industry, interaction between water and steel is bound to happen even on land. If steel will be used close to the coastline, the degree of corrosion protection has to be appropriate. The slightest hint of rust on a critical part of the structure can force the beams to snap and make the structure crumble. That's why stainless steel is a common option for the structure's requirements if it happens to be near a body of water.
Expect water to be a structural risk even for ststructural steel in Melbourne; pick the right defense. For the most up-to-date in the Australian steel market, you can have a look at innovation.gov.au/Industry/Steel/Pages/default.aspx.
