Stainless steel is arguably the most well-known metal alloy on the planet and yet, its uses go far beyond cutlery and cooking pots. This substance is also used in ship repair services due to its numerous benefits.
One of the most beneficial aspects of stainless steel is that it is resistant to atmospheric and aqueous corrosion. This makes it an ideal substance to be used within the maritime industry. Other metals such as carbon steel are much less durable and over time, they will need to be repaired or replaced. Stainless steel offers a greater sense of longevity; particularly when referring to pieces that are regularly exposed to harsh conditions such as pressure vessels.
While the anti-corrosive advantages of stainless steel cannot be overlooked, it is nonetheless a metal that can be difficult to work with due to its innate hardness. This is one of the reasons why machining precision parts can be challenging. One method to circumvent this innate characteristic is to add small amounts of other materials such as sulphur or phosphorous. AISI grades 416 and 303 are common examples of these unique alloys.
However, the benefits of the hardness associated with stainless steel far outweigh CNC machining challenges. Keep in mind as well that technology has come a long way in recent years. Thanks to harder cutting surfaces and highly precise computer-aided software, the entire process is much easier. This ultimately saves the client money and increases the overall ROI.
The Addition of Protective Coatings
To be sure, stainless steel will often suffer some form of localised corrosion (such as pitting or cracking) over time. These instances can be avoided through the use of protective coatings such as specially engineered paints. Other processes including heat treating can help to strengthen the molecular bonds between the steel atoms themselves, offering an even greater level of strength.
Stainless steel is a revolutionary material and it can address countless ship repair concerns. However, it is still wise to choose a professional CNC machine shop to guarantee that the work is carried out in a precise manner.
