Special material stainless steel is mainly produced with a thickness of 0.02mm-3.1mm and a width of 1mm-1500mm
Relying on the company's domestic and foreign processing equipment and logistics network throughout the country
From customer orders to fit stock screening
Then to processing, production, re-inspection and distribution
Our R&D team has established good cooperative relations with domestic and foreign steel mills
Timely and efficient cooperation with customers for product development
Combined with a Japanese-funded continuous electroplating factory, we have successfully launched gold-plated, silver-plated, nickel-plated and other electroplating products.
Products have broad market prospects and development potential
Stainless steel strip protective film (mainly PE protective film) is used to protect the surface of the board during storage, cutting, bending, and stamping processes, preventing scratches, indentations, and dust pollution. The selection of the film coating needs to match the surface type, processing technology, service environment, and peeling time of the stainless steel, referring to GB/T 20878
Flattening, also known as smoothing, is a small reduction rate rolling process after cold rolling and annealing. The reduction rate is usually only 0.5-3%, without changing the material thickness specifications. It relies on the rolling mill to lightly press the surface of the steel strip, and its main functions are as follows:
1、 At the material level (source priority) 1. Reasonably reduce the hardness of materials For the same grade, the lower the hardness, the higher the elongation, and the smaller the rebound. Example: The original rebound of 301-3/4H was too large. If conditions permit, it can be changed to 301-1/2H, and the rebound will significantly decrease; The cost is a decrease in elasticity, an
Stamping hardware is the use of punching machines to punch, bend, and stretch sheet metal. Stainless steel coils are used as raw materials for coil materials, taking into account material properties, coil processing advantages, corrosion resistance, appearance, and mass production. They are widely used in various stamping hardware parts.
Core storage risks of stainless steel strips: iron ion contamination, rust, moisture pitting, surface scratches, coil deformation, mixed material errors, label loss. Once rust spots appear on austenitic stainless steel, they are difficult to remove.
Fundamental problem: Iron ion pollution (free iron pollution) causes induced corrosion on the surface of stainless steel, rather than the corrosion resistance failure of the stainless steel material itself.
Stainless steel coils are widely used in various equipment manufacturing, pipeline systems, container lining and other scenarios in the chemical industry due to their excellent corrosion resistance, high temperature resistance, strength and processability. They are the core material for dealing with complex media (such as acids, alkalis, salts, organic solvents, etc.) and harsh working conditions
1. Different production processes Stainless steel hot rolling is rolled above the recrystallization temperature of the metal material, and stainless steel cold rolling is rolled below the recrystallization temperature of the metal material, and each metal material has its own recrystallization temperature. crystallization temperature.
