Hot Forming

Both 410 and 410S stainless steels exhibit excellent plasticity at elevated temperatures, making them well-suited for various hot working processes such as hot rolling, forging, and hot extrusion. This high-temperature plasticity allows these materials to be easily shaped and formed into complex geometries without compromising their structural integrity or mechanical properties.Hot working these stainless steels enhances their versatility in manufacturing, allowing them to be used in producing components that require both corrosion resistance and high strength. Applications that benefit from these forming processes include the production of turbine blades, valves, and industrial machinery parts, where durability and performance in high-heat environments are critical. Their ability to be hot worked into intricate shapes also expands their use in the automotive and aerospace industries, where precision and heat resistance are key.

Cold Forming

410 and 410S stainless steels both exhibit moderate plasticity at room temperature, making them suitable for various cold forming processes, such as cold rolling, bending, deep drawing, and cold extrusion. These processes allow for the creation of intricate and precise components without the need for high-temperature operations. However, 410S stainless steel, with its lower carbon content, demonstrates slightly higher plasticity compared to Type 410. This enhanced plasticity makes 410S more advantageous for cold forming applications, as it reduces the risk of cracking or deformation during the manufacturing process. Consequently, 410S is often preferred for applications that require complex shapes or detailed features, while still maintaining the material's overall strength and corrosion resistance. This makes both grades versatile choices for industries such as automotive, aerospace, and manufacturing, where high performance and precision are essential.

Welding

410 and 410S stainless steels both exhibit good welding properties, making them suitable for various welding techniques such as arc welding, laser welding, and resistance welding. These methods are commonly employed to join stainless steel components, ensuring strong and durable welds. However, Type 410S stainless steel, with its lower carbon content compared to Type 410, offers distinct advantages during welding. The reduced carbon content in 410S facilitates better control over the uniform distribution of carbon throughout the weld zone. This characteristic helps to minimize the risks associated with carbon precipitation and the formation of pores, which can lead to weld defects and compromise the integrity of the joint.

NO.1

The NO.1 surface is achieved through heat treatment and pickling after hot rolling. It has a silver-white, matte appearance with a subtle sheen. This surface finish is ideal for applications where heat and corrosion resistance are crucial, but surface brightness is not a priority. It is commonly used in industries such as industrial storage tanks, chemical processing plants, and other environments that demand durability and resistance to harsh conditions.

2D

The 2D surface finish is produced through heat treatment and pickling after cold rolling, resulting in a silver-white appearance with a smoother yet matte texture. This surface is widely used in applications that require both durability and a refined appearance. Common uses include petrochemical production equipment, automotive parts, building materials, and water pipes, where strength and corrosion resistance are essential, but a highly polished surface is not necessary.

2B

Following the 2D treatment, the material undergoes a final light cold rolling process using a polishing roller to achieve a subtle gloss. The resulting surface is smooth, bright, and can be easily re-polished to enhance its shine further. This finish is commonly used in applications such as building materials and tableware, where an aesthetically appealing and easy-to-maintain surface is important.

NO.4

The NO.4 finish is achieved by grinding with a belt of grit size 150-180, resulting in a surface with improved gloss, finer lines, and more refined stripes compared to the rougher NO.3 finish typically used for polished and sanded stainless steel surfaces. This finish is widely applied in industries such as food processing equipment, household appliances, and medical equipment, where a smooth, aesthetically pleasing surface with enhanced durability is required.

BA

The BA (Bright Annealed) surface is produced through cold rolling and de-scaling, resulting in an excellent surface gloss and high reflectivity. Its extremely smooth finish makes it ideal for additional finishing processes like mirror polishing and chrome plating. Due to its superior appearance and durability, the BA surface is commonly used in applications such as catering equipment, where both functionality and aesthetic appeal are important.

HL

The HL (Hairline) finish is achieved by grinding with a polishing abrasive belt of suitable grit size (150-320 mesh), resulting in distinct, straight stripes on the surface. This finish provides an attractive appearance with a good texture, where scratches are less visible. It is known for its durability and wear resistance. Common applications for the HL finish include building decoration, elevators, and vehicle parts, where a stylish and resilient surface is required.

Mirror

The Mirror finish is achieved by polishing with progressively finer abrasives and extensively buffing the surface until all scratches from initial grinding are eliminated. This process results in the highest level of reflectivity. It is primarily used for both interior and exterior decorative materials in automobiles and buildings, where a high-gloss, reflective surface is desired.
