Product Introduction

310 Stainless steel clad plate, also known as 310 stainless clad steel plate, is a composite material made by bonding stainless steel plate (cladding material) to either or both sides of a carbon steel or low alloy steel plate (base metal). Bonding will form a diffusion layer between these two kinds of plates. That diffusion layer has a stable mechanical performance without obvious grain micro-structure, and its internal mechanical properties show a graded change in the thickness direction.

Moreover, this kind of plate unites the good weldability, ductility, and thermal conductivity of carbon steel and the high corrosion resistance, abrasion resistance, and magnetic resistance of stainless steel. Thus it features excellent cost-effectiveness when being applied in many different applications.

How Is the Plate Made?

The plate is readily fabricated by standard industrial procedures. Upon request, it is usually divided into explosion cladding and rolling cladding.

1. Explosion Cladding

This is how the explosion-bonded 310 SS clad plates are made. When the 310 stainless steel plate is superimposed on a carbon steel plate, the explosive will be laid on the surface of the stainless metal. Once bursting, the energy generated by the explosion makes the cladding material hit the base material at a very high speed. Meanwhile, the high temperature and high pressure prompts these two materials to be fused and welded together at the interface of two materials. Ideally, the shear strength per square millimeter of the interface can reach 400 MPa.

Compared with the traditional cladding method, explosive adhesion features a super high bonding strength and corrosion resistance, as well as improved mechanical and thermal performance. Meanwhile, explosion bonding technology can produce a clad plate with a total thickness of up to 200mm. What’s more, SS clad plates of round shape can only be produced by explosion bonding.

2. Rolling Cladding

Before the rolling process, the surfaces of stainless steel and carbon steel will be cleaned appropriately by a grinding machine to remove contaminants or an oxide layer. When rolling, it is often divided into hot rolling and cold rolling.

1. Hot Rolling

Hot rolled 310 stainless steel clad plate is made by the following steps: when the carbon steel substrate and stainless steel plate are in a physically pure state, the two plates will be rolled under high vacuum conditions. Firstly, the carbon steel will be stacked with stainless steel and the plate edges will be welded with four carbon steel seals. A hole will be drilled in the middle of one seal, and the air in the plate interface will be pumped out through the hole by a vacuum pump reaching a proper vacuum degree (0.5 P — 5 Pa). After being heated to a temperature of 1100℃ for 3h in a pit furnace, the plate was multiple-pass rolled at a temperature of 800℃ before being cooled in the air.

Hot rolled 310 stainless cladding plates are a leading-edge material. It ensures the features of low price, high strength, good corrosion resistance, oxidation resistance, wear resistance, and more than 50 years of service life.

2. Cold Rolling

Cold rolled 310 stainless steel clad plate is manufactured on the basis of hot rolled 310 stainless clad plate. When the hot rolled 310 stainless clad plate is cooled to room temperature, it will go through annealing, pickling, cold rolling, intermediate annealing, pickling (or bright annealing), tension leveling, and other production processes. The surface of cold rolled 310 stainless clad plate reaches the surface quality of the same series of stainless steel, and the yield strength is better than that of the same grade of stainless steel. With the thinnest thickness of 0.6mm, it is much more suitable for the civil field and decoration projects.

Why People can Trust it?

310 SS clad plate features strong points of carbon steel and stainless steel. It has numerous benefits you can enjoy:

1. Good Corrosion Resistance: the stainless steel material contains high chromium, which forms a protective oxide layer on the surface. It can provide strong resistance to various corrosive media, including acids, alkalis, moisture, rust, stains, and other environmental factors.

2. High-temperature Resistance: this sort of plate contains 25% chromium and 20% nickel, making it highly resistant to corrosion and oxidation to 2000°F. So it is an ideal choice for projects that require service at temperatures up to 1150 degree Celsius.

3. Good Processing Performance: due to a strong metallurgical bonding formed by carbon steel and stainless steel, it is very ductile and has good weldability, including hot pressing, cold bending, cutting, machining, and so on.

4. Light Weight: as a metal material, it is always has lightweight but high strength. What’s more, the thickness of cladding metal constitutes only 10–20 % that of the stainless steel clad plate.

5. Flat & Smooth Surface: it possesses a smooth and non-porous surface, making it easy to clean and maintain hygiene standards and highly suitable for industries with stringent cleanliness requirements.

6. Cost-effective Solution: it is a resource-saving material. Compared with pure stainless steel plates, the stainless steel clad plates can reduce alloy elements like Cr and Ni by 70–80 % and reduce costs by 30–50 % because of the low cost of carbon steel. It realizes the perfect combination of low cost and high performance, having good social and economic benefits.
