HL Stainless Steel Sheets

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.

Material: HL stainless steel sheets are available in a variety of materials, such as 304, 316, 321, etc., and the appropriate material should be selected according to actual needs.

Supplier Reputation: It is very important to choose a reliable HL stainless steel sheets suppliers, they should provide high quality products, reasonable price and timely delivery.

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.
