Stainless steel clad steel bimetallic plate
1. Stainless steel: All in the air or all kinds of gases, in water or all kinds of acid, alkali, salt water solution with high chemical stability will not rust or corrosion of steel, all become stainless steel.
According to the chemical stability of stainless steel in different corrosive media, stainless steel can be divided into:
A. ordinary stainless steel -- steel that resists corrosion in air.
B. stainless acid resistant steel - resistant to corrosion in strongly corrosive acid solutions.
Stainless steel can be divided into ferritic stainless steel, martensitic stainless steel and austenitic stainless steel according to their microstructure after normalization. In addition, there are intermediate type stainless steels, such as martensitic ferrite stainless steel.
2. Carbon steel carbon steel is an iron-carbon alloy, but also contains a small number of beneficial elements manganese and silicon, as well as impurity elements sulfur and phosphorus. Carbon steel is divided into low carbon steel, medium carbon steel and high carbon steel.
3. Low-alloy steel is a kind of low-alloy steel which adds a certain amount of alloy elements (less than 5%) on the basis of carbon steel to improve the strength of the steel and ensure its plasticity and toughness, or to make the steel have some special properties (such as low temperature resistance, high temperature resistance or corrosion resistance).
4. Alloy steel alloy steel is based on carbon steel into one or more elements (its weight is more than 5%) in order to significantly improve the strength, toughness and wear resistance of steel, and has good hardenability.
Structural stainless steel, carbon steel, low alloy steel and alloy steel materials are often used in explosive welding process, and mainly plate, followed by pipe and bar.
Stainless steel clad steel bimetallic plate, the composite plate composed of stainless steel plate and steel (carbon steel, low alloy steel or alloy steel) plate is made of stainless steel-steel composite plate. This kind of composite plate has both the characteristics of stainless steel and ordinary steel. This composite board is of great significance for saving alloy resources, reducing material consumption and reducing costs.
Manufacturing method of stainless steel steel composite plate:
A. butt welding method B. casting C. rolling D. explosive welding E. explosive welding + rolling method
Clad steel plates are widely used in pressure equipment, chemical equipment, oil refining equipment and synthetic industrial equipment. The thickness of the coating is usually 5%-20% of a total thickness. The material of carbon steel layer of composite steel plate is A515, A515, A204, A387, A32, A36 and so on. The coating materials are AISI 405, 410, 410S, 429, 430, 304, 309, 316 and 321, as well as nickel alloy 200, Inco nickel 600 and Monel 400.

Petroleum refineries are one of the sectors with the largest volume of composite materials, mainly used in vacuum towers, distillation towers and various heat exchangers. Chemical equipment mainly includes various reaction towers, precipitation tanks, agitators, desalination equipment and various types of heat exchangers. In addition, a large number of stainless steel-steel composite boards are used in synthetic fiber manufacturing and paper industry, such as dyeing vats, washing towers and autoclaves, evaporators in caustic soda and salt industry.
In addition, the three-layer stainless steel-steel-stainless steel composite plate sheet is widely used in kitchen utensils, kitchen machinery, swimming pool, sink, water heater and building materials because of its beautiful metallic luster, excellent corrosion resistance, excellent adhesion resistance, excellent heat conductivity and good processability.
