Production Description of HL Stainless Steel Sheets
HL stainless steel sheets, also known as hairline stainless steel sheets, are widely used in various industries due to their unique surface finish.
HL stainless steel sheets are stainless steel sheets that have a polished and passivated surface. The process involves grinding the surface of the stainless steel sheet using abrasive belts, which creates a fine, linearly textured surface similar to hairlines. This is where the name HL stainless steel sheets comes from (HL is an abbreviation for Hairline). This surface treatment technique creates a uniform, non-directional texture pattern on the surface without changing the physical properties of the stainless steel sheet, resulting in a smoother, more lustrous surface and better corrosion resistance.
HL stainless steel sheets have excellent corrosion resistance, high strength and good malleability, making them ideal for a wide range of applications. They are commonly used for cladding, roofing and wall panels in the construction industry, as well as furniture, kitchen appliances and decorative finishes in the interior design industry.

Production Process of HL Stainless Steel Sheets
High-quality stainless steel plates are selected as raw material and cut to the required size.
The stainless steel sheets are roughly ground using a grinding machine to remove scratches and oxides from the surface.
Medium grinding of the stainless steel sheets with a medium grinding wheel to further improve the surface finish.
Polishing the stainless steel sheets with a high-speed rotating polishing wheel to make the surface reach the HL level of finish.
Soak the stainless steel sheets in acid for pickling to remove oxides and other contaminants from the surface.
Use the fine-grinding wheel to fine-grind the stainless steel sheets to make the surface smoother.
Features of HL Stainless Steel Sheets
The surface of HL stainless steel sheets is characterized by a uniform and fine frosted texture, similar to a sand grain effect, which is more softly reflective compared to mirror stainless steel sheets and does not leave visible fingerprints or scratches due to the touch of fingers or other objects. The surface of HL stainless steel sheets is treated by abrading or polishing the stainless steel surface to achieve a frosted or polished effect. Huaxiao Stainless steel sheets suppliers offer a wide range of HL stainless steel sheets in various specifications to meet the needs of different customers.
HL stainless steel sheets surface are polished and have very high finish, which can reflect the image of the object, and the surface effect is beautiful and has a strong decorative character.
HL stainless steel sheets are made of stainless steel material, which have excellent corrosion resistance and can keep the surface finish and durability in wet environment for a long time, avoiding rusting and corrosion.
HL stainless steel sheets have good processing performance and can meet the processing needs of various shapes and sizes, such as shearing, bending, punching, drilling, etc.
HL stainless steel sheets can maintain their physical properties even in high temperature environments, without embrittlement, and can withstand high temperature heat treatment.
HL stainless steel sheets are non-toxic and tasteless, will not be harmful to human body, in line with food hygiene requirements, commonly used in food processing, catering and other places.

For example, cell phones, tablet PCs, laptops, and other mobile devices in the shell, keyboard, mouse, etc. are likely to use HL stainless steel sheets to make. In addition, because HL stainless steel sheets have good electrical conductivity, they can also be used to make electronic devices and connectors, etc. Huaxiao Stainless Steel Sheets Suppliers is also a highly trusted supplier of HL stainless steel sheets that are used in a wide range of applications in electronic products.
The surface roughness of HL stainless steel sheets usually ranges from Ra 0.4 to 3.0 microns. Generally, the higher the grade, the lower the surface roughness of the stainless steel sheet. HL stainless steel sheets surface roughness is between No.4 and No.8 and is more suitable for applications where a certain glossy and tactile feel is required.
HL stainless steel sheets and No.8 stainless steel sheets are two different surface treatments. HL stainless steel sheets refers to hairline (brush) treatment, the surface shows a pattern similar to brush scratches and has a certain glossy finish, but it is less mirror-like than No.8 stainless steel sheets. While No.8 stainless steel sheets are treated with multiple grinding, polishing and waxing, the surface presents a very smooth, mirror-like effect. Therefore, there are differences between HL stainless steel sheets and No.8 stainless steel sheets in terms of appearance, surface treatment, and usage.
HL stainless steel sheets are more resistant to rust and corrosion than other stainless steel sheets, but rust may still occur if they are subjected to corrosive media such as strong acids, alkalis and salts for a long time. Therefore, care needs to be taken to avoid contact with these corrosive media during use and to clean the surface dirt in time to maintain the surface finish and corrosion resistance of stainless steel.
HL stainless steel sheets usually have no color, it is finished by grinding and polishing to give a matte-like gloss to its surface. If color needs to be added to HL stainless steel sheets, the surface can be painted in different colors through special treatments such as chemical oxidation or electrochemical coloring. Some of the common coloring methods include gold, rose gold, black, bronze, etc. The color depends on the special treatment and process. Huaxiao Stainless Steel Suppliers also offers HL stainless steel sheets in a wide range of colors for customers to choose from.
When selecting HL stainless steel sheets, you should pay attention to the following points:
Determine the Use: HL stainless steel sheets have many different uses, such as construction, decoration, kitchen equipment, chemical industry, automotive industry and electronic products. Before purchasing, you should be clear about the desired use.
Specification Requirements: The specifications of HL stainless steel sheets such as thickness, width, length and weight vary from application to application, so you need to choose the right specification according to the specific situation.
Surface Quality: The surface quality of HL stainless steel sheets is very important and attention should be paid to whether there are defects such as scratches, dents, oxidation and stains on its surface.

HL stainless steel sheets usually have higher hardness and harder surface, so they are also more difficult to process compared to general stainless steel sheets. More specialized equipment and tools, such as high-speed drills and tungsten carbide blades, are required for processing such as cutting, drilling and stamping. In addition, because of the high surface finish of HL stainless steel sheets, care needs to be taken to avoid scratching, abrasion and other damage to the surface during processing. Taken together, the HL stainless steel sheets are more difficult to process and require corresponding professional techniques and equipment to complete.
HL stainless steel sheets require some maintenance to maintain their beauty and function. Generally speaking, cleaning and maintaining HL stainless steel sheets requires the following points:
- Avoiding the use of cleaning agents containing chlorine ions and fluoride, as they can corrode and damage stainless steel;
- Using mild detergents and soft cloths to clean the surface, avoiding the use of rough brushes, wire balls, etc. to scrape the surface;
- Cleaning and wiping surfaces regularly, especially in environments with corrosive gases, salt water or chemicals;
- Taking care to keep the surface in the same direction during cleaning and not to rub in a circular or opposite direction to avoid damage to the surface;
- Avoid placing high temperature items or using chemicals such as strong acids and alkalis for a long time on the HL stainless steel sheets to avoid damaging the surface and structure.
