Iron and steel room temperature phosphating technology
Introduction
The phosphating of steel at room temperature is a common process that is used to improve durability and improve corrosion resistance of steel surfaces. In this process, the surface of the steel is treated with a phosphoric acid solution to produce a protective film on the surface of ......
The basic principle of phosphating - pretreatment before phosphating
Phosphating is a process in which a series of salts are applied to metal surfaces to improve their rust protection and painted surface adhesion. In order for phosphating to be effective, proper surface preparation must take place prior to its application. This includes ridding the metal surfaces o......
Dual-phase steel hot-dip galvanizing technology
Duplex Steel Hot-dip Galvanizing Technology
The hot-dip galvanizing technology for duplex steel is considered an environmentally preferable option for the process of steel coating. This technology not only protects steel from corrosion, but it also has numerous other benefits such as improved we......
Introduction to the formula of water-soluble quenching liquid (2)
Formulation of Water-Soluble Carburizing Liquids
Carburizing liquids are used to enable the surface of metals to meet design requirements. These liquids are designed to increase the surface carbon content of the metal, which provides strength and durability.
There are two major types of carburiz......

Hot Rolled Steel Bar for Prestressed Concrete (GB4463-1984)
Prestressed concrete is a general term for concrete structures prestressed by artificial means. In order to meet the needs of various large-span engineering structures, prestressed concrete has become an important type of rei......
Tin plate production
Tinplate Manufacturing
Tinplate is a method of creating steel products that involve coating the steel product with a thin layer of tin. The thin layer of tin helps increase the resistance of the product to corrosion, rust, and tarnish. Additionally, tinplate steel is able to provide strength, dur......
Finishing process
What is a Finishing Process?
Finishing processes refer to a variety of post-processing or post-manufacturing processes used to improve the appearance and fit of a metal product. Finishing processes are typically employed after initial shape forming procedures such as metal cutting, stamping, lase......
Bar pitting and its causes and prevention methods
Bundling bars and its Causes and Treatments
Bundling bars, sometimes known as bar marks or bar spots, are dark spots visible on bars of steel, aluminium and other metals. While bundling bars may raise concerns about the quality of metals, this form of discolouration is often harmless and does not......
Roll inspection
Steel Roll Inspection
Steel roll inspections are critical to the function and integrity of hot, cold, and coated rolled mill production processes. Properly performed, these inspections can ensure structural steel components will perform as anticipated in their often challenging and demanding appl......
