Plates Stainless Steel Composite Wear-Resistant 304 + Q235B Composite Sheet

Product Description

Stainless steel clad plate is a composite plate made of carbon steel base and stainless steel cladding. Its main feature is that carbon steel and stainless steel form a solid metallurgical combination. It can be used for hot pressing, cold bending, cutting, welding and other processing with good process performance.

The base material of stainless steel composite plate can use Q235B, Q345R, 20R and other ordinary carbon steel and special steel. The coating materials can be 304, 316L, 1Cr13 and duplex stainless steel. The material and thickness can be freely combined to meet the needs of different users. Stainless steel clad plate is a new industrial product, which not only has the corrosion resistance of stainless steel, but also has the good mechanical strength and processing performance of carbon steel. Stainless steel composite plate has been widely used in petroleum, chemical industry, salt industry, water conservancy and power industry. As a resource saving product, stainless steel composite plate can reduce the consumption of precious metals and greatly reduce the project cost. Realize the perfect combination of low cost and high performance, with good social benefits.

Production Method

How is stainless steel clad plate produced? There are two main methods for industrial production of stainless steel clad plate, explosive cladding and hot rolling cladding.

The production process of explosive clad plate is to overlap the stainless steel plate on the carbon steel substrate, and a certain distance is separated between the stainless steel plate and the carbon steel substrate with a cushion. The stainless steel plate is paved with explosives. The energy of explosive explosion makes the stainless steel plate impact the carbon steel substrate at high speed, producing high temperature and high pressure, so that the interface between the two materials can realize solid phase welding. Ideally, the shear strength per square millimeter of the interface can reach 400 MPa.

The hot rolled composite plate process is made of carbon steel substrate and stainless steel plate in a physical pure state, rolled under high vacuum conditions. In the rolling process, the diffusion of the two metals realizes complete metallurgical bonding. Of course, in order to improve the wetting effect and bonding strength of the composite interface, a series of technical measures should be taken in the physical and chemical treatment of the interface. The above two composite plate manufacturing methods shall comply with GB/T8165-2008 national standard. This standard is not equivalent to the Japanese JISG3601-1990 standard, and its main technical indicators are the same or higher than the Japanese standard.
