Introduction of 430 Stainless Steel Hot Rolled Plate

430 stainless steel hot rolled plate is a type of stainless steel sheet that has been processed using hot rolling techniques. It is a widely used material in various industries due to its excellent corrosion resistance, good mechanical properties, and low cost compared to other grades of stainless steel. In this article, we will provide an overview of 430 stainless steel hot rolled plate, discussing its properties, and applications.

Properties of 430 Stainless Steel Hot Rolled Plate:

430 stainless steel has good corrosion resistance, excellent thermal conductivity compared to austenite, and satisfactory thermal expansion coefficient. Additionally, by adding titanium as a stabilizing element, it also benefits the mechanical properties of the weld seam. Therefore, it is a widely used general stainless steel grade. Due to the proportion of chromium content, it is also referred to as 18-0. Compared to 18-8 and 18-10, its hardness is relatively lower due to the slightly lower chromium content.

430 stainless steel has antioxidant and corrosion resistance properties, but it is susceptible to intergranular corrosion.

The Surface and Processing Technology of 430 Stainless Steel Hot Rolled Plate：

The surface grades and states of 430 stainless steel are numerous, including NO.1, 1D, 2D, 2B, N0.4, HL, BA, Mirror, and various other surface treatment states. These different states have different dirt and corrosion resistance.

The 1D surface has a discontinuous particle texture and is also called a matte finish. The processing sequence for this surface is hot rolling, annealing and shot blasting with acid pickling, cold rolling, and annealing and acid pickling.

The 430 stainless steel 2D surface is slightly shiny and silvery white. The processing sequence for this surface is hot rolling, annealing and shot blasting with acid pickling, cold rolling, and annealing and acid pickling.

The most common surface of 430 stainless steel is the 2B surface, which is silvery white with better gloss and flatness than the 2D surface. The processing sequence for this surface is hot rolling, annealing and shot blasting with acid pickling, cold rolling, annealing and acid pickling, temper rolling.

The BA surface has a highly reflective mirror-like finish. The processing sequence for this surface is hot rolling, annealing and shot blasting with acid pickling, cold rolling, annealing and acid pickling, surface polishing, temper rolling.

The No.3 surface has a better gloss and a coarse texture. This surface is processed by polishing 2D or 2B products with 100~120 grinding materials (JIS R6002) and temper rolling.

The No.4 surface of 430 stainless steel usually has good gloss and a fine texture. This surface is processed by polishing 2D or 2B products with 150~180 grinding materials (JIS R6002) and temper rolling.

The HL surface typically appears silvery gray with hairline stripes. This surface is processed by polishing 2D or 2B products with an appropriate grade of grinding material to create a continuous grinding texture.

The MIRRO surface is a mirror finish, achieved by polishing 2D or 2B products with an appropriate grade of grinding material to create a mirror-like finish.

Applications：

430 stainless steel wire is often used in the manufacturing of axles. In addition, because the material is safe and non-toxic, it is also widely used in food and tableware. It can also be used to make architectural decoration, fuel burner components, household appliances, and home appliance components. With technological advancements, the excellent properties of 430 stainless steel will continue to be utilized, making it another widely popular stainless steel model after 304 stainless steel.
