In this guide, we’ll cover everything you need to know about stainless steel fabrication in Melbourne, including its techniques & applications:

What is Stainless Steel Fabrication?

Stainless steel fabrication involves the transformation of raw materials into products or items that can be used in construction or assembly. A structural and fabrication operation utilizes steel, which is an alloy of iron and other metals. It is used to form metal into the shape of your choosing.

Over 150 grades of stainless steel are available. With at least 10.5 % chromium, it is a low-carbon alloy. By adding chromium, an inert layer of chromium oxide is created. As a result of the chromium oxide layer, the steel is corrosion-resistant and possesses a spotless finish. In addition to nickel, molybdenum, titanium, sulphur, and manganese, other alloying agents may be present.

Benefits of Stainless Steel Fabrication

Stainless steel is used phenomenally in vast industries & the following are the advantages of using fabricated stainless steel for industrial purposes:

1) Ease of Fabrication:

In contrast to the aluminium conductor, this metal can be used in a variety of ways. Fabrication involves cutting, welding, stamping, and tooling stainless steel. It might seem challenging to fabricate. Under the guidance of a professional, stainless steel can easily be cut, welded, bent, machined, assembled, and fabricated under modern machining and tooling. Precise extensive processing of stainless steel grades enables fabrication in a wide range of applications.

2) Resistant to Rust and Corrosion:

Corrosion resistance is one of the main reasons why most industries invest in stainless steel. Chromium plays a significant role in preventing rust from forming on steel.

3) Resistant to Heat:

The stainless-steel material is also fire and heat-resistant. In this way, it elevates its usability and makes it one of the most important metals of all time. Both nickel and chromium alloyed stainless steel can be used to make valves, heat exchangers, boilers, water heaters, etc.

4) Long-Term Value:

Stainless steel’s high price is often criticized. Despite this, the metal contributes significantly to the performance and longevity of the infrastructure. Intangibles are frequently overlooked yet play an important role in the long run.

5) Strength:

One of the most promising factors that allocate stainless steel used to different industries is its strength. Due to its innate strength at extreme temperatures, it is able to resist impacts. In the aviation industry, stainless steel is preferred because of its high strength-to-weight ratio.

6) Appearance:

As a result of its clean architectural aesthetic, stainless steel has long been a popular choice in commercial and residential settings.

7) Environmental Friendliness and Sustainability:

The stainless-steel material is 100% recyclable. Due to the fact that most of the materials are already recycled, there is no need for further mining. Additionally, stainless steel does not leach toxic chemicals into the environment.

8) Cost-Effectiveness:

The price of stainless steel remains competitive due to consistent market demand. In spite of the higher initial investment, and lower fabrication, installation, and maintenance costs, long-term durability, and recyclability help keep the whole life cycle cost as low as possible.

9) Hygiene and Maintenance:

A high standard of hygiene is imparted by stainless steel. As a result of its smooth surface, bacteria cannot breed on it and can be easily sanitised and maintained. 

Raw Materials Used in Stainless Steel Fabrication

Choosing the right raw materials can help speed up the fabrication process, ensuring that workers have access to what they need to produce high-quality stainless steel products. 

Fabricators usually work with plate metal to shape the pieces. In addition, manufacturers often use castings and fittings to enhance the aesthetics of their creations.

These are some of the most common and readily available raw materials used in fabrication:

  • Plate metal
  • Castings
  • Fittings
  • Flat metal
  • Sectional metal
  • Welding wire
  • Hardware
  • Formed & expanded metal

5 Steps Process in Stainless Steel Fabrication

Stainless steel fabrication processes include:

1) Work Hardening:

It is possible to harden metals upon cold forming, depending on the stainless-steel grade used in the manufacturing process. Austenitic stainless steels work harden rapidly, but 400-series stainless steels have a higher cold working rate than plain carbon steels. By hardening, we increase the metal’s hardness. 

2) Machining:

In general, the higher the alloying content of steel, the more difficult it is to the machine. Thus, stainless steel is more difficult to machine. In machining, milling, turning, drilling, and threading are all processes.

3) Welding:

It is true that almost all stainless steel grades can be welded, but each stainless steel grade has different weldability, with Austenitic grades being the easiest. A stainless steel’s weldability depends on its type or group. The process of welding involves joining together different parts by applying high heat or pressure and then cooling them. 

4) Soft Soldering:

Soft soldering involves heating the parts to be joined, causing the solder to melt and adhere to the workpieces in a surface alloying process known as wetting – soft solder filler metals with a liquidus temperature below 662 Fahrenheit/350 degrees Celsius.

5) Silver Soldering (Brazing):

In cases where welding is not possible, silver soldering, also known as brazing, provides a strong joint. By melting and flowing a filler metal into the joint, different parts are joined. Through silver soldering, steels, coppers, mild steels, brasses, and cast irons are treated.

Stainless Steel Fabrication Applications

1) Construction and Architecture:

A stainless steel detail or design is commonly used in the building and construction industry. Stainless steel covers the exteriors of both large and small buildings. Engineers around the world use stainless steel for bridge construction because of its strength, corrosion-resistant properties, and aesthetic appeal. The material can also be used for interior features such as handrails, backsplashes, countertops, and public restrooms.

2) Goods and Appliances:

Many appliances used in commercial kitchens and restaurants, as well as household kitchens, are fabricated from stainless steel. There are stainless steel parts and panels in dishwashers, refrigerators, freezers, ovens, microwave ovens, and even toasters. Washing machines and other household appliances are also made of stainless steel.

3) Aerospace & MoD:

As a result of its strength, durability, and ability to withstand extreme temperatures, stainless steel is highly valued in the aerospace and defence industries. 

4) Medical Applications:

Its biocompatibility and hygienic characteristics make stainless steel excellent for medical devices, instruments, and tools. Austenitic stainless steel grades 304 and 316 are medical-grade stainless steels used in hypodermic needles, implants, stents, and surgical devices.

5) Food Processing and Equipment:

Due to its easy cleaning properties, stainless steel is the best choice for applications requiring strict hygienic conditions. In food processing, it can be found in vats and tanks, refrigeration units, countertops, tables, sinks, and cookware. Aside from knives, spoons, and forks, stainless steel is also used in cookers, grills, and saucepans. It is easy to clean, doesn’t absorb flavors, and can be kept germ-free, which makes stainless steel perfect for kitchenware.
