439 Stainless Steel Coil
Type 439, a titanium-stabilized 18% chromium alloy, is a ferritic stainless steel designed to resist corrosion in a wide range of oxidizing environments from fresh water to boiling acids.Type 439 is also used in many oxidizing environments, where Type 304 is considered adequate for general corrosion resistance, but is subject to chloride stress corrosion cracking. This variation does not require post-weld annealing to restore ductility or provide resistance to intergranular corrosion.
Excellent resistance to stress corrosion cracking, good weldability, high thermal conductivity and low thermal expansion properties make Type 439 stainless steel ideal for many applications.

Heating and hardening methods
Steel has a critical temperature at which it becomes ductile and begins to change its chemical structure. When steel is heated above this temperature, it enters what is known as the austenite stage.
From this point on, engineers can create the correct shape and quality of steel that they need. There are many ways to heat treat steel, including but not limited to:
Annealing - heating and then slowly cooling the steel to refine it and make it softer
Carburizing - using heat and carbon-rich materials to add carbon to the surface
Surface Hardening - Carburizing and rapidly cooling the steel so that the center remains soft and the rest hardens
Cyanide Hardening - similar to surface hardening, but uses molten cyanide salts instead of carbon to form a hard shell
Decarburization - removing carbon from a steel alloy by heat or oxidation
Nitriding - adding nitrogen to the surface of steel using heat and a nitrogen-rich liquid or gas
Stretching or Tempering - reheating steel that has been cooled to a specific temperature to remove hardness

Hot Dipped Galvanized Coil
Hot-dipped galvanized coil refers to a product that is created by immersing steel coil into a bath of molten zinc. This process is known as hot-dip galvanizing and results in a protective coating of zinc being applied to the steel surface.
How does the hot-dipped galvanizing (HDG) process work?
This technique, also called HDG, is now a lot more common. Galvanizing is basically the process of adding a coating on any base metal for the purpose of increasing corrosion resistance and durability. Hot-dip galvanizing is a form of galvanization. It is the process of coating iron and steel with zinc. That is, the surface of the base metal is coated with a zinc layer by immersing the metal in a bath of molten zinc at a temperature of around 450 �°C (842 �°F).
Galvanized steel is widely used in applications where corrosion resistance is needed. But its cost is much lower than the cost of stainless steel.
Hot Dipped Galvanized Steel Coils
Hot-dip galvanizing refers to the process of applying a protective zinc coating to a steel sheet or iron sheet, in order to prevent rusting. As the full hard steel has undergone acid washing followed by a rolling process through the zinc pot, a layer of zinc film is applied to the sheetâ??s surface. Henceforth, hot dipped galvanized steel sheet in coil (GI) is produced. High quality hot dipped galvanized steel coil with reasonable price is a popular steel product with high level of corrosion resistance, paintability, and workability. It is frequently used in a broad spectrum of industries and sectors. As China galvanized steel coil suppliers, Hunter is determined to supply highly cost effective galvanized steel coil in China. Meanwhile, Hunter could give customers reasonable hot dipped galvanized steel coil price.
FEATURES OF HOT DIPPED GALVANIZED STEEL COIL
Thanks to the self-sacrificing characteristic of zinc, hot dipped galvanized steel coils are capable of outstanding performance in regard to anti-corrosion ability processability.
Steel manufacturers can select and produce the desired amount of zinc gilded and in particular enables thick zinc layers (maximum 120g/m2).
AR500 Steel Plate
AR500 steel plate has a high surface hardness for excessive wear and high impact applications.
What is AR500 steel plate?
AR500 is an Abrasion Resistant (AR) steel plate known for its hardness, toughness and wear resistance. This grade is one of the hardest of the common AR steel plate grades - with Brinell hardness values (BHN) ranging from 460-544 - and is typically used in high wear and impact applications. AR500 steel plate meets the ASTM E10 specification for Brinell hardness testing.
Overview:
Wear resistant steel plates for high wear applications such as mining equipment and concrete handling.
Surface hardness range of 470-540 BHN.
Excellent resistance to sliding wear, frictional wear and heavy wear.
Withstands high impact stresses even at very low temperatures.
Advantages of AR500 steel plate
The hardness and toughness of AR500 steel plate makes it extremely resistant to wear and impact. These properties make AR500 steel a durable, long-lasting material, which is essential for applications that require materials that can withstand extreme wear and tear.
The durability of AR500 also means that the material needs to be replaced less often than less wear resistant materials, which reduces material costs and prevents devastating equipment failures.

Cold Rolled Carbon Steel Sheets
Cold rolled carbon steel is hot rolled steel that has been further processed. Hot-rolled steel is cooled (usually to or below its recrystallization point), then annealed and re-rolled at room temperature to obtain more accurate thicknesses, higher strength and hardness, and better surface quality. In addition to changing mechanical properties, the cold rolling process produces steel with tighter tolerances and higher dimensional accuracy than hot rolled steel. It also tends to be better suited to lighter gauges and is better suited to applications that require a more visually appealing surface finish.
Types of Cold Rolled Carbon Steel
Cold rolled carbon steel is available in a variety of carbon content levels:
Low carbon steel - also known as soft steel, contains less than 0.3% carbon. It is highly formable, making it effective for applications that require a lot of bending and forming.
Medium Carbon Steel - Carbon content ranges from 0.3% to 0.6%, which makes it stronger and more durable for applications such as automotive manufacturing.
High-carbon steel - contains 0.61% to 1.5% carbon, which significantly alters its physical properties. With higher carbon content, the steel becomes stronger and harder than mild steel; however, this material is less ductile.
