The key to the heat resistance of stainless steel sheets lies in their composition, which typically includes high levels of chromium, nickel, and other alloying elements. These elements provide excellent resistance to oxidation and corrosion at high temperatures, allowing the sheets to maintain their structural integrity and mechanical properties even when subjected to prolonged heat exposure.

Heat-resistant stainless steel sheets are available in various grades, such as 310S, 309S, and 253MA, each offering specific heat resistance properties suitable for different temperature ranges and environmental conditions. These sheets are also available in different surface finishes, thicknesses, and sizes to accommodate a wide range of industrial and commercial applications.

When selecting heat-resistant stainless steel sheets, it’s important to consider factors such as the operating temperature, mechanical strength, and corrosion resistance required for the specific application. Proper installation and maintenance practices are also crucial to ensure the long-term performance of heat-resistant stainless steel sheets in high-temperature environments.

Overall, heat-resistant stainless steel sheets are essential components in industries such as petrochemical, power generation, and aerospace, where the ability to withstand high temperatures is critical for the performance and longevity of the equipment.

Stainless Steel Plate Surface Finish

Through different processing methods of cold rolling and surface reprocessing after rolling, the surface finish of stainless steel sheets can have different types.

The surface processing of stainless steel sheet have NO.1, 2B, No. 4, HL, No. 6, No. 8, BA, TR hard, Rerolled bright 2H, polishing bright and other surface finishes, etc.

NO.1: No. 1 surface refers to the surface obtained by heat treatment and pickling after hot rolling of the stainless steel sheet. It is to remove the black oxide scale produced during hot rolling and heat treatment by pickling or similar treatment methods. This is No. 1 surface processing. The No.1 surface is silvery white and matt. Mainly used in heat-resistant and corrosion-resistant industries that do not require surface gloss, such as alcohol industry, chemical industry and large containers.

2B: The surface of 2B is different from the 2D surface in that it is smoothed with a smooth roller, so it is brighter than the 2D surface. The surface roughness Ra value measured by the instrument is 0.1～0.5μm, which is the most common processing type. This kind of stainless steel sheet surface is the most versatile, suitable for general purposes, which is widely used in the chemical, paper, petroleum, medical and other industries, and can also be used as a building curtain wall.

TR Hard Finish: TR stainless steel is also called hard steel. Its representative steel grades are 304 and 301, they are used for products that require high strength and hardness, such as railway vehicles, conveyor belts, springs and gaskets. The principle is to use the work hardening characteristics of austenitic stainless steel to increase the strength and hardness of the steel plate by cold working methods such as rolling. The hard material uses a few percent to several tens of percent of the mild rolling to replace the mild flatness of the 2B base surface, and no annealing is carried out after rolling. Therefore, the TR hard surface of the hard material is the rolled after cold rolling surface.

Rerolled Bright 2H: After the rolling process. the stainless steel sheet will be processed bright annealing. The strip can be fast cooled by the the continuous annealing line. The traveling speed of the stainless steel sheet on the line is around 60m~80m/min. After this step, the surface finish will be 2H rerolled bright.

No.4: The surface of No. 4 is a fine polished surface finish that is brighter than the surface of No. 3. It is also obtained by polishing the stainless steel cold-rolled stainless steel plate with 2 D or 2 B surface as the base and polishing with abrasive belt with a grain size of 150-180# Machined surface. The surface roughness Ra value measured by the instrument is 0.2～1.5μm. NO.4 surface is widely used in restaurant and kitchen equipment, medical equipment, architectural decoration, containers, etc.

HL: HL surface is commonly called hairline finish. Japanese JIS standard stipulates that 150-240# abrasive belt is used to polish the continuous hairline-like abrasive surface obtained. In China’s GB3280 standard, the regulations are rather vague. HL surface finish is mostly used for building decoration such as elevators, escalators, and facades.

No.6: The surface of No. 6 is based on the surface of No. 4 and is further polished with a Tampico brush or abrasive material with a particle size of W63 specified by GB2477 standard. This surface has a good metallic luster and soft performance. The reflection is weak and does not reflect the image. Due to this good property, it is very suitable for making building curtain walls and building fringe decorations, and also widely used as kitchen utensils.

BA: BA is the surface obtained by bright heat treatment after cold rolling. Bright heat treatment is annealing under a protective atmosphere that guarantees that the surface is not oxidized to preserve the gloss of the cold-rolled surface, and then use a high-precision smoothing roll for light leveling to improve the surface brightness. This surface is close to a mirror finish, and the surface roughness Ra value measured by the instrument is 0.05-0.1μm. BA surface has a wide range of uses and can be used as kitchen utensils, household appliances, medical equipment, auto parts and decorations.

No.8: No.8 is a mirror-finished surface with the highest reflectivity without abrasive grains. The stainless steel deep processing industry also calls as 8K plates. Generally, BA materials are used as raw materials for mirror finishing only through grinding and polishing. After mirror finishing, the surface is artistic, so it is mostly used in building entrance decoration and interior decoration.
