Advantages of Stainless Steel

1. Beautiful surface and versatile uses

2. It has good corrosion resistance and is more durable than ordinary steel.

3. High intensity

4. High temperature oxidation resistance and fire resistance

5. Processing at room temperature, easy to plastic process

6. Due to the lack of surface treatment, maintenance is simple and easy

7. Clean and well treated surface

8. Good welding performance

Common grades of stainless steel coils

Level 1.304/1.4301. 304 grade stainless steel coils have always been a popular grade choice due to their significant corrosion resistance and excellent weldability, and are known for their ease of forming or rolling forming. Type 304 is widely used in household items (1 and 2 tableware), cabinets, indoor pipes, water heaters, boilers, bathtubs, automotive parts, medical equipment, building materials, chemicals, food industry, agriculture, and ship components.

Level 2.316/1.4404. In places where higher corrosion resistance is required, such as in marine environments, 316 is the preferred choice. Due to the addition of molybdenum element, this grade of material is particularly resistant to pitting corrosion.

Level 3.321/1.4541. The 304 variant has added titanium to make it stronger. 321 grade stainless steel strip has excellent welding characteristics and is particularly resistant to intergranular corrosion damage. Common applications of 321: Suitable for chromium carbide precipitation range (800-1500 ° F, 427-815 ° C), aircraft exhaust pipes, manifolds, chemical processing equipment, welding equipment, jet engine components, heat exchangers, expansion joints.

430 level/1.4016. 430 grade is mainly used in the catering industry and other domestic industries. It is a ferritic alloy with good corrosion resistance.

Popular surface treatment options for stainless steel coils

When purchasing stainless steel coils, Kruper Steel also offers a comprehensive range of surface treatment options. Popular surface treatment options include:

1.2D. The 2D surface is also subjected to cold rolling treatment, resulting in a matte surface with low reflectivity.

2. HR/No. 1. This hot-rolled surface has a flake like appearance, making it very suitable for situations where the final aesthetic requirements are not high.

3. BA/2R. Cold rolling and annealing are carried out in a controlled atmosphere to maintain a highly reflective surface. This highly reflective surface is achieved by annealing the alloy in a strictly controlled atmosphere.

4.2B. Smooth finish, reflective gray luster. The most widely used surface treatment. 2B is the most popular surface treatment, with a smooth appearance and a gray reflective luster.
