What Is The Manufacturing Process Of Hot Rolled Stainless Steel Clad Plate?

Nov. 16, 2018

Stainless Steel Clad Plate is a whole combination of stainless steel and other steel grades (such as carbon structural steel, carbon tool steel, single metal, alloy, etc.) in a certain way. It is a kind of stainless steel and other materials. , Explosive composite panels reduce production costs, but also meet the actual needs of new materials. It is widely used in petroleum, chemical, seawater desalination, nuclear industry, food industry, water conservancy facilities and other industries. Compared with the pure stainless steel of the same specification, the proportion of stainless steel is significantly reduced, thereby saving 40% to 50%, and saving rare metals such as Cr and Ni by 70% to 80%.

The heat treatment of the Stainless Steel Composite Plate is also a key part in the production process of the composite sheet. The strength of the composite steel sheet after the explosion of the metal composite material is increased, the hardness is increased, and the plasticity is reduced, which is not conducive to the subsequent straightening and application requirements. The heat treatment process is actually to eliminate the internal stress after the explosion composite and improve the plasticity. However, due to the fact that stainless steel has its own solution treatment system, it is inevitable to conflict with the heat treatment system of carbon steel. For example, ultra-low carbon two-phase OOCrl 8Ni5 Mo3Si2, OOCr22Ni5 Mo3 N, etc. stay at 950 °C for a long time and tend to precipitate Fe. Cr intermetallic brittle. Phase, this will seriously deteriorate the plasticity and resistance of intergranular corrosion of stainless steel. The normal normal temperature of carbon structural steel is around 890 °C. Long-time over-temperature heating will lead to coarse grain and lower toughness. Combinations like this are particularly important in terms of heat treatment temperatures, holding times, and the choice of cooling regime.

In addition, the heat treatment system also has a great influence on the shear strength of composite plates. The metal composite plate is based on 1 Cr18Ni8Ti + 16Mn composite plate. When the heat treatment temperature is higher than 400 °C, the shear strength is obviously decreased due to the coarse grain in the base layer. However, the impact toughness, bending properties, and elongation can be significantly improved as the heat treatment temperature is increased.
