Stainless steel coil

Stainless steel coils are an important type of metal material. They are made from stainless steel plates through the winding process. They have excellent corrosion resistance, strength and toughness. Their surfaces are smooth and tidy and can be cut and processed into various products according to demand. They are widely used in many fields such as construction, manufacturing, kitchenware, etc., and are indispensable materials in modern industry.

Application:

1. Construction field:

used for building facade, roof, balcony railing, etc. For example, many modern high-rise buildings will use stainless steel coil to create a unique and durable appearance. Its corrosion resistance and aesthetic characteristics make the building able to maintain a good appearance for a long time.

2. Manufacturing industry:

In automobile manufacturing, stainless steel coil can be used to manufacture auto parts, such as exhaust pipes, decorative strips, etc. Automobile exhaust pipes need to withstand high temperature and corrosion. The high temperature resistance and corrosion resistance of stainless steel coil just meet the needs.

3. Kitchenware industry:

Most of the common stainless steel pots, pots, tableware, etc. are processed from stainless steel coil. The sanitary, easy cleaning and corrosion resistance of stainless steel coil make it an ideal material for kitchen utensils manufacturing.

4. Chemical industry:

Due to its good corrosion resistance, stainless steel rolls are used in the manufacture of chemical containers, pipes, etc. In chemical plants, pipes made of stainless steel rolls can transport various corrosive chemicals without being damaged.

5. Electronics industry:

Stainless steel rolls are used in the shell and internal structural parts of some electronic equipment, such as mobile phone frames, computer cases, etc. 6. Medical field: Stainless steel rolls are often used in medical apparatus such as surgical instruments, hospital bed parts, etc. It is easy to disinfect and clean, and can meet the strict requirements of medical hygiene.

Physical properties of stainless steel coils:

1. Density: Usually around 7.93 grams per cubic centimeter, relatively high.

Melting point: generally between 1398 and 1454 degrees Celsius, depending on the composition of the stainless steel.

3. Thermal conductivity: Thermal conductivity is relatively poor, with a thermal conductivity of about 16.3 to 37.1 W/(m · K).

4. Conductivity: It has a certain degree of conductivity, but it is not as good as metals such as copper and aluminum.

5. Magnetic: Most stainless steel coils are non-magnetic or weakly magnetic at room temperature, but some types may be magnetic during processing or under specific conditions.

 

The chemical properties of stainless steel coils:

1. Corrosion resistance: This is one of the most important chemical properties of stainless steel coils. It can resist corrosion in the atmosphere, water, acid, alkali and other environments.

2. Oxidation resistance: It can resist oxidation in high temperature environments and maintain surface integrity and performance. For example, in high temperature industrial production environments, equipment made of stainless steel rolls can run for a long time without being severely oxidized.

3. Stability: The chemical composition of stainless steel coils is relatively stable and does not easily react with other substances. However, chemical changes may still occur in some strongly oxidizing media or under specific conditions.

Stringent product quality inspection

Surface quality inspection
Use the surface roughness detector to inspect the surface roughness, the adhesion and thickness of the coating (if any).
Appearance inspection
Check whether there are scratches, pits, rust spots, oxide skin and other defects on the surface of steel products.
tensile test
Determine indicators such as tensile strength, yield strength, elongation, etc., and evaluate the strength and plasticity of the steel plate.
Galvanized layer inspection
Make sure that the thickness of the galvanized layer meets the specified requirements to provide adequate corrosion protection.
Size detection
Measure the diameter, length, and thickness of steel pipes to ensure they meet specific customer requirements.
Spectral Analysis
Examining Steel Composition Through Emission Spectra Using Advanced Spectroscopic Methods and Techniques
Bending detection
Observe whether there are cracks, folds, peeling and other defects on the surface of the bent steel plate.
non-destructive testing
Used to detect internal defects in steel, such as cracks, pores, etc.

Inventory and Package

Plate package

steel plates together using steel bands and then wrapped in waterproof paper or plastic sheets to protect against moisture and corrosion

Coil package

Steel coils are wrapped in waterproof paper or plastic sheeting and sometimes further protected with metal sheet covers.

Pipe package

Pipes are usually bundled together and strapped. Ends are often capped to prevent damage and ingress of dirt,anti-corrosion measures.

Rod package

The bundles are then wrapped with waterproof material, and sometimes, anti-rust oil or coatings to prevent corrosion.
