Classification of Stainless Steel

Austenitic Stainless Steels

The most frequently used, austenitic stainless steels tend to have a higher amount of chromium compared to other steel alloys, giving them a higher resistance to corrosion. They're also generally non-magnetic alloys, though cold working can change that.

Ferritic Stainless Steels

As their name suggests, these stainless steel alloys are magnetic. They're also the second most common stainless steel after austenitic varieties. Manufacturers can harden these alloys using cold working techniques. Ferritic stainless steels are often less expensive, as well, due to the reduced nickel content in their makeup.

Duplex (Ferritic-Austenitic) Stainless Steels

This stainless steel category gets its name from the material's composition, which is half austenite and half delta-ferrite. With a higher tensile strength than typical austenitic varieties, duplex stainless steels express better resistance to corrosion and chloride pitting.

Precipitation-Hardening (PH) Stainless Steels

This stainless steel category is made up of corrosion-resistant, durable, exceptionally strong alloys. Manufacturers can treat PH stainless steels to yield strengths up to four times that of standard austenitic alloys. They're a common occurrence in nuclear, oil and gas, and aerospace industries.

Stainless-Steel Surface Treatment

Electrolysis polishing
By applying a positive voltage to stainless steel in a mixed solution of acids consisting mainly of phosphoric acid, micro-peak of the rough surface of stainless steel are preferentially dissolved.It improves corrosion resistance and provides smooth and glossy surface.

Pickling
The stainless steel is immersed in a mixed solution of nitric acid and hydrofluoric acid to dissolve the surface. It helps to clean the surface by completely removing contamination, oxide layer and welding scale.

Passivation treatment
Stainless steel is treated with a special solution to dissolve and remove foreign matter (e.g. iron) attached to the surface at the time of machining.In addition, the chromium component on the stainless steel surface is concentrated to form a stable oxidized layer, resulting in a highly corrosion-resistant surface.

TF treatment (special passivation treatment）
The chrome-Rich oxide layer is formed on the surface of stainless steel to significantly improve corrosion resistance.This is our unique treatment technique that greatly improves the resistance to saltwater.

Chemical oxidation for coloring stainless steel
A transparent oxide coating is developed on the surface of stainless steel which changes the surface to vivid color.

The Stainless Steel Manufacturing Process

The meltshop
The meltshop is the first step in the stainless steel manufacturing process. Raw materials are melted in an electric arc furnace before carbon, sulfur, and any nitrogen are removed in a steel converter. The steel composition is then fine-tuned in ladle treatment before the molten steel is cast into slabs or ingots.

Hot rolling
In hot rolling, the microstructure of semi-finished casting products such as slabs, blooms, or billets is broken down and deformed. The deformed grains recrystallize, which maintains an equiaxed microstructure (a structure in which the grains have approximately the same dimensions in all directions) and prevents the steel from work hardening.

Cold rolling
Cold rolling involves rolling wide sheets of stainless steel between small-diameter working rolls backed by two or three layers of supporting rolls. The steel strip profile and flatness are carefully controlled during the process.

Annealing and pickling
Annealing and pickling (AP) is a process used to restore the properties of stainless steel after cold rolling by recovering and recrystallizing the deformed microstructure. A typical cold rolled AP line has a pre-treatment phase, which is often an electrolytic pickling step in a neutral solution based on sodium sulfate or an acidic step based on nitric acid. A bright annealing (BA) line can also be used to restore the material properties, where the steel strip is treated in a protective atmosphere of hydrogen, or a mixture of hydrogen and nitrogen.

Final processing
Final processing, also called finishing, is where stainless steel coils and plates are tailored according to the requirements of the end customer. This can involve processes like levelling of a plate or coil, slitting or cutting coils into rows or sheets, edge preparation for welding, and surface preparation like grinding, pattern rolling, or brushing.

Application of Stainless Steel

Medical Equipment – Stainless steel is used extensively in modern medical equipment due to its ease of sterilization and high corrosion resistance. Surgery and dental instruments, surgical tables, and larger equipment such as MRI scanners are all made from stainless steel material.

Aircrafts and Aerospace – Aircraft must be able to resist a wide range of climatic conditions, including extremes in temperature, precipitation, and elevation pressures. The qualities of stainless steel enable it to easily address all of these issues, making it the most essential material for aircraft and aerospace applications.

Building and Construction – Stainless steel is a fantastic construction material since it is both strong and flexible. Because of its corrosion resistance, it provides structures a superb modern aesthetic while still being easy to maintain.

High-pressure Applications – Stainless steel’s strength makes it ideal for building, but it also makes it resistant to high pressure and temperatures. As a result, stainless steel is an excellent choice for high-pressure applications such as energy systems like power plants.

Food Industry – Stainless steel is advantageous in food and catering applications for many of the same reasons that it is advantageous in medical equipment. Stainless steel makes for fantastic, sharp knives and can endure high heat for cooking, in addition to being easy to clean.

FAQ

Q: Why is stainless steel preferred?

A: Stainless steel has a good transformation capacity (easy to weld, bend and cut). Stainless steel has an inert surface that prevents any contamination of the final product and thus protects your process from any form of contamination. Stainless steel is hygienic and easy to clean. It does not require much maintenance.

Q: Why is stainless steel healthier?

A: Its non-porous surface does not allow bacteria and makes cleaning easy since food particles and germs do not mount on surfaces. Stainless steel is ideal for cooking utensils, food processing, and even kitchen devices that have to remain hygienic.

Q: Why is stainless steel so expensive?

A: Stainless steel is defined as low-carbon steel. It does not readily stain with water, corrode or rust like ordinary steel. Stainless steel is more expensive to produce because of the addition of the variety of alloying elements, such as iron, chromium, nickel, manganese and copper.

Q: Is stainless steel good for everyday?

A: Conclusion. Stainless steel is a versatile material appearing everywhere in our daily lives and industries! Its durability, corrosion resistance, and ease of maintenance make it a go-to choice for many applications.

Q: How long will stainless steel last?

A: Outdoor Applications – Exposure to rain, pollution, and varying temperatures can accelerate wear. However, stainless steel remains resistant to rust and degradation, typically lasting 50+ years.
