Types of Stainless Steel Shape
 

There Are Mainly the Following Types

316 Stainless Steel Square Tube

The 316 stainless steel square tube is a premium product widely used across industries due to its exceptional corrosion resistance, strength, and durability.

Super Duplex 2507 Pipe

Super Duplex 2507 is a high-performance stainless steel alloy known for its superior mechanical properties and resistance to corrosion.

Custom Thin Wall Stainless Steel Tube/pipe

A seamless stainless steel tube is a tubular component that draws or extrudes a steel blank through a die. Without any joints or welding, a seamless pipe is perfect for applications that require high pressure or extreme temperatures because it does not suffer from the stress concentration or weak spots of a welded pipe.

Hot Rolled Stainless Steel Plate

Hot rolled stainless steel plate is a flat product obtained after rolling stainless steel slabs at high temperatures. It's well-known for its scaling resistance, strength at high temperatures, and good weldability, making it pivotal in construction, heavy industry, and transportation.

Seamless Stainless Steel Tube

The seamless stainless steel tube, a robust and versatile material, is made from an alloy that combines elements like iron, carbon, nickel, and chromium. Because it's made without a welded seam, it offers superior pressure resistance and can be used in a variety of heavy-duty applications.

Stainless Steel Cold Rolled Coil

Stainless steel cold rolled coil is versatile and widely used products known for their excellent properties, making them essential in various industries. These coils undergo a cold rolling process, resulting in improved surface finish, dimensional accuracy, and mechanical properties compared to hot rolled coils.

 

Advantages of Stainless Steel

Corrosion Resistance

Chromium is the alloying element that imparts to Stainless Steel their corrosion-resistant qualities. Lower alloyed grades resist corrosion in atmospheric and pure water environments; high-alloyed grades can resist corrosion in most acids, alkaline solutions, and chlorine bearing environments making their properties useful in process plants.

 

Fire and Heat Resistance

Special high chromium and nickel-alloyed grades resist scaling and retain high strength at high temperatures. Stainless steel has a high melting point, which means it can withstand elevated temperatures without melting or deforming.

Hygiene

Stainless steel tubing has a smooth, non-porous surface that is easy to clean and maintain. It is commonly used in critical applications such as food and beverage processing, pharmaceutical manufacturing, biotechnology, medical devices, and cleanroom environments.

Aesthetic Appearance

The bright easily maintained surface of stainless steel provides a modern and attractive appearance. The availability of various finishes, including brushed, polished, and satin, provides designers with versatility to achieve specific aesthetic effects, ensuring stainless steel tubing's enduring appeal in a wide range of applications.

Strength-to-Weight Advantage

The work-hardening property of austenitic grades results in a significant strengthening of the material from cold-working alone, and the high strength duplex grades, allow reduced material thickness over conventional grades yielding considerable cost savings.

Surface Treatment Methods for Stainless Steel

 

 

1. Polishing

Process Effect: For carbon steel, polishing improves smoothness but requires protective coatings for corrosion resistance. For alloy steel, it enhances surface uniformity, with passivation or coating recommended for corrosion-prone alloys. For stainless steel, it creates a smooth, reflective surface ideal for aesthetics and industrial use.
Shapes: Flat sheets, tubes, rods, bars, structural sections, plates, complex curved surfaces, angles.
Number: No. 3, No. 4, 1G, 2G, 4G

2. Brushing

Process Effect: Carbon steel gets a textured finish but needs protective coatings to prevent rust. Alloy steel gains a satin finish for decorative purposes. Stainless steel results in a matte finish suitable for both decorative and industrial use.
Shapes: Flat sheets, plates, pipes, tubes, rods, bars, square tubing, structural shapes, curved surfaces.
Number: No. 4, No. 5, No. 6, 1J, 2J

3. Passivation

Process Effect: Carbon steel is not suitable for passivation, and electroplating or coating is recommended. Alloy steel can benefit from passivation, improving corrosion resistance. Stainless steel passivation removes contaminants and enhances corrosion resistance.
Shapes: Pipes, tubes, fittings, fasteners, complex shapes, sheets, rods, bars.
Number: No. 2B, No. 2D, 2B1, 2B2, 2G

4. Pickling

Process Effect: Carbon steel needs protective coatings post-pickling to prevent corrosion. Alloy steel removes oxides and may require passivation for protection. Stainless steel restores its corrosion-resistant layer, improving durability.
Shapes: Pipes, tubes, sheets, plates, coils, structural sections, bars, rods, fittings.
Number: No. 1, No. 2B, No. 1D, 2F, 1G

5. Mirror Finish

Process Effect: Carbon steel requires a protective coating after achieving a mirror finish. Alloy steel benefits from the reflective finish but needs corrosion protection. Stainless steel achieves a high-gloss finish, ideal for decorative and functional applications.
Shapes: Flat sheets, tubes, rods, bars, plates, architectural elements, complex surfaces, decorative pieces.
Number: No. 8, SB, 2P, 2R, 3R

 

6. Etching

Process Effect: Carbon steel needs protection after etching to avoid corrosion. Alloy steel can be etched for both functional and decorative purposes, with post-etching treatments needed. Stainless steel maintains its corrosion resistance while allowing custom designs.
Shapes: Sheets, plates, flat surfaces, tubes, rods, panels, architectural elements.
Number: No. 5, No. 2K, 2E, 2R, 4G

 

How to Pack Stainless Steel Coil

 

Stainless steel coil packaging and loading

Packaging

According to customers' needs, use wrapping paper. If the transpor tation period exceeds 10 days or encoun- ters special climate, we will use waterproof packaging and add plastic fim to prevent moisture, water and rust.

Loading

We use the wooden pallettriangular wood to fix the coiland the steel wire rope to hold on the both side. That can prevent from the crush injury effectively.

FAQ

 

Q: Why is stainless steel preferred for custom made solutions?

A: Stainless steel is preferred due to its malleability, resistance to corrosion, unmatched strength, and longevity. It's ideal for crafting solutions that demand precision, durability, and aesthetic appeal.

Q: Why is stainless steel essential for aerospace applications?

A: Precision is crucial in the aerospace industry. Stainless steel offers a high strength-to-weight ratio, ensuring safety and optimal functionality for aircraft components.

Q: What are the primary technical processes involved in stainless steel fabrication?

A: The main processes include design and prototyping, cutting and shearing, forming and bending welding and assembly, and surface treatment. Advanced software tools and machinery are used to ensure precision throughout these stages.

Q: How is stainless steel shaped?

A: Hot rolling helps get the steel into a rough shape, and is often used to create billets or blooms of metal. To create metal blooms or billets of precise dimensions, the stainless steel may be cold rolled. Heat Treatment/Annealing.

Q: How is stainless steel transported?

A: Stainless steel products, such as sheets and coils, can be transported using flatbed trucks, but it is crucial to protect them from moisture and other elements. Tool steel is a type of steel that is specifically designed for use in cutting, drilling, and shaping other materials.

Q: How to tell what grade of stainless steel?

A: There are different ways to help narrow down each type, including a spark test. Spark tests involve grinding an unknown metal to view the sparks created. The color, length, and forking of the sparks help professionals identify the steel. Another common test is the Brinell Hardness test.

Q: How should stainless steel be stored?

A: Climate-controlled storage - When subjected to extreme humidity, stainless steel can suffer from rusting. Therefore, it's important to store the material in a climate-controlled setting to prevent moisture build-up. You might use dehumidifiers in storage areas to maintain optimal conditions.
