The product technology of precision stainless steel strips is recognized as a high-precision core technology in the field of stainless steel production in the world today. Due to its very strict requirements on precision tolerance, mechanical properties, surface roughness, brightness, hardness and other indicators, it has become a unique top product in the strip steel industry. At present, there are the following misunderstandings about precision stainless steel strips in the market:
The most difficult problem in welding thin 304 stainless steel plates is welding penetration and deformation. The main measures to solve the burn-through and deformation of thin stainless steel plates are as follows:
430 stainless steel coils have the following states. Different states have different resistance to dirt and corrosion. NO.1, 1D, 2D, 2B, N0.4, HL, BA, Mirror, and various other surface treatment states. The 1D surface has a discontinuous granular shape, also known as a matte surface. Processing technology: hot rolling + annealing shot peening pickling + cold rolling + annealing pickling.
When we process stainless steel plates, we generally use mechanical polishing, chemical polishing, electrochemical polishing and other methods to achieve mirror stone luster according to the complexity of stainless steel products and user requirements. The advantages and disadvantages of these three methods are described below:
The heat treatment of stainless steel strip is to eliminate the work hardening after cold rolling, so that the finished stainless steel strip can achieve the specified mechanical properties. In the production of stainless steel strip, the commonly used heat treatment methods are as follows:
1. There is an identification liquid for stainless steel strips on the market, and you can know which type of stainless steel it is by detecting the nickel content in the stainless steel strip. 2. Magnetic identification of 304 stainless steel strip, generally the larger magnetic is 2 series stainless steel strip, non-magnetic or weaker magnetic is 3 series stainless steel strip (but these two methods can not clearly determine whether it is 304 stainless steel).
