High Strength 430 Stainless Steel Hot Rolled Plate Supports Polished Brushed Cutting Round

430 stainless steel plate, hot-rolled industrial plate, supports polishing, brushing, cutting round plate

430 stainless steel is a general-purpose steel with good corrosion resistance, better thermal conductivity than austenite, smaller thermal expansion coefficient than austenite, heat fatigue resistance, and good mechanical properties of the weld part due to the addition of the stabilizing element titanium. 430 stainless steel is used for architectural decoration, fuel burner parts, household appliances, and home appliance parts. 430F is a steel with easy-cutting properties added to 430 steel, mainly used for automatic lathes, bolts and nuts, etc. 430LX adds Ti or Nb to 430 steel and reduces the C content, improving the processing and welding properties. It is mainly used for hot water tanks, hot water supply systems, sanitary appliances, household durable appliances, bicycle flywheels, etc.

Due to its chromium content, it is also called 18/0 or 18-0. Compared with 18/8 and 18/10, it contains slightly less chromium and the hardness is correspondingly lower.

Applications Stainless steel will not corrode, pit, rust or wear.

Function: Used as containers for food, such as pots, bowls, basins, etc. Used for architectural decoration and oil burner parts.

‌430 stainless steel plate‌ is a ferritic stainless steel with good corrosion resistance and stable physical properties. Its chemical composition mainly includes carbon (C) ≤0.12%, silicon (Si) ≤0.75%, manganese (Mn) ≤1.00%, phosphorus (P) ≤0.040%, sulfur (S) ≤0.030%, nickel (Ni) ≤0.60% (included), chromium (Cr) 16.00~18.00%. In some cases, molybdenum (Mo) 2.00~3.00%‌ may also be included.

Physical properties
The density of 430 stainless steel plate is 7.75g/cm³ and the melting point is 1427℃. Its thermal conductivity is better than that of austenitic stainless steel, its thermal expansion coefficient is small, and its thermal fatigue resistance is good‌.

Corrosion resistance
430 stainless steel plate has good corrosion resistance under most environmental conditions and is not easy to rust. However, it cannot resist oxidation caused by chemicals in the air, so oxidation (rust) may occur in an environment with more chemicals‌.

Application fields
430 stainless steel plates are widely used in architectural decoration, fuel burner parts, household appliances, home appliance parts, etc. Due to its relatively low price, it is often used as an alternative to 304 stainless steel. In addition, specific models such as 430F and 430LX have free cutting performance and improved processing and welding performance, respectively, and are suitable for automatic lathes, bolts, nuts, hot water tanks, hot water supply systems, sanitary appliances, etc.

There is another type of stainless steel, 201, 202, 203, 204, which has low chromium content and high manganese content (high chromium can increase corrosion resistance, and high manganese can make the material non-magnetic). This type of stainless steel has poor corrosion resistance and is generally used for decoration in dry environments.

Grading and Process
Surface Grade
430 stainless steel has the following states, and different states have different dirt resistance and corrosion resistance.
NO.1, 1D, 2D, 2B, N0.4, HL, BA, Mirror, and various other surface treatment states.
Featured Processing Technology
1D—The surface has discontinuous granularity, also known as matte. Processing Technology: hot rolling + annealing shot peening pickling + cold rolling + annealing pickling.
2D—Silver-white with a slight gloss. Processing Technology: hot rolling + annealing shot peening pickling + cold rolling + annealing pickling.
2B—Silver-white with better gloss and flatness than 2D surface. Processing Technology: hot rolling + annealing shot peening pickling + cold rolling + annealing pickling + tempering rolling.
BA—The surface has good gloss and high reflectivity, like a mirror surface. Processing Technology: hot rolling + annealing shot peening pickling + cold rolling + annealing pickling + surface polishing + tempering rolling.
No.3—has good glossiness and coarse grain on the surface. Processing technology: polish and temper rolling with 100~120 abrasives (JIS R6002) for 2D or 2B.
No.4—has good glossiness and fine grain on the surface. Processing technology: polish and temper rolling with 150~180 abrasives (JIS R6002) for 2D or 2B.
HL—silver gray with hairline grains. Processing technology: polish 2D or 2B products with abrasives of appropriate grain size to make the surface continuous.
MIRRO—mirror-like. Processing technology: polish 2D or 2B products with abrasives of appropriate grain size to a mirror effect.

Material properties
430 stainless steel has the ability to resist oxidation and corrosion, but has a tendency to intergranular corrosion.
430 stainless steel wire is widely used in axles.
Because it is safe and non-toxic, it is widely used in food and tableware.
