Everything That You Need To Know About Stainless Steel In Marine Applications.

You will often find stainless steel in marine applications, and there are a good number of reasons for this. It is widely known as the ideal material for marine applications because it has excellent resistance to corrosion as well as good appearance, stability, durability, lustre, strength, and stiffness.

Marine environments are very demanding, with factors like water flow rates, high salt content, pressure, and temperature all coming into play together. Stainless steel marine fitting in Sydney structures can usually withstand these elements and ensure that difficult projects can go ahead that may otherwise seem impossible.

Stainless steel is ‘fit for purpose

There are many factors to consider when choosing which kind of stainless steel is right for your project. These include:

• Seawater quality

• Water flow rates

• Water temperature

• Water oxygen levels (deaeration)

• ‘Engineered’ crevices (post fabrication cleaning and surface finish)

• Cathodic protection

There are many types of stainless steel, and each one has different benefits and uses. Let’s look at some of them:

• 304 stainless steel marine fitting in Sydney is apt for applications such as splash zone applications, coastal service environments, and intermittent submersion in seawater. It uses the metal for fully exposed components that are frequently washed with fresh water.

• Super-austenitic stainless steels like 6% moly are advised for applications where they will be permanently submerged in seawater. 6% Moly is a super-austenitic stainless steel marine fitting in Sydney which contains a minimum of 6% molybdenum. 6% Moly alloys have exemplary resistance to a number of chemicals which are particularly appropriate for environments such as seawater, brackish water, pulp mill bleach plants that have a high chloride condition

• Duplex stainless steels provide higher strength which means that lighter weight components can be used for the same applications as 316. It is common to find duplex stainless steel marine fitting in Sydney, especially in brackish water, such as in estuaries where the content of chloride in the water is less than that of the open sea.

• Super duplex stainless steels offer even more strength and weight than that duplex and are able to withstand all the challenges of marine surroundings with no risk of corrosion even in hot and tropical waters and wet exhaust applications. They can even be used in prolonged and direct contact with seawater, such as on offshore oil platforms.

Examples of stainless steel in marine applications

There are many types of stainless steel marine fitting in Sydney, such as:

• Coastal applications such as housings for equipment, handrails, ladders, and lamp posts.

• Deck components for ships and boats, e.g., brackets for anchor ropes, deck eyes housings for equipment, shackles, and handrails.

• Submerged items such as sewage and water, pipelines and grills for oil, risers for oil platforms, grills, coastal power plants, heat exchangers for ships, equipment attached to hulls of boats and ships, etc.

• Prolonged contact items such as winches, pumps, holding and storage vessels, etc.
