F55: A super duplex stainless steel F55 is a kind of super duplex stainless steel, superior to the 2205 in overall performance. “Super” refers to the high alloying of its components. Compared with other duplex stainless steels, the high alloying of super duplex steels mainly refers to high molybdenum and nitrogen. The characteristics performance are (1) excellent resistance to stress corrosion cr...

First, the principle of pickling passivationThe corrosion resistance of stainless steel is mainly due to the higher content of Cr added to the steel (such as 316L W (Cr) = 16.00 ～ 18.00). Cr is easily oxidized and can form a dense Cr2O3 oxide film on the surface of the steel. The electrode potential of the steel and the corrosion resistance in the oxidizing medium are suddenly improved. The corros...

This type of steel was developed in the late 1980s. The grades are mainly SAF2507, UR52N, Zeron100, etc. It is characterized by low C content, high Mo and high N, and ferrite phase content in steel accounts for 40% to 45%. , has excellent corrosion resistance.

It inherits the characteristics of high strength, good oxidation resistance and excellent stress corrosion resistance of ordinary ferritic stainless steel, and improves the ductility of brittle-brittle transition, sensitivity to intergranular corrosion and low toughness of welded state. Refining technology, reducing C and N content, adding stabilizing and weld metal toughening elements, can obtain...

It is a hardenable stainless steel with high hardness, strength and wear resistance, but has poor toughness and weldability. Ordinary martensitic stainless steel lacks sufficient ductility and is very sensitive to stress during deformation, and cold forming is difficult.

Etc. 316 stainless steel forgings contain a large amount of alloying elements such as nickel and chrome. The processing in the forging factory can significantly c...

The main role of nickel content in stainless steel is that it changes the crystal structure of the steel. One of the main reasons for the addition of nickel in stainless steel is the formation of austenitic crystal structures, which improve the properties of stainless steels such as plasticity, weldability and toughness, so nickel is called an austenite forming element.The crystal structure of ord...

All stainless steel products are 100% recyclable. Many recycling companies will want the various grade types to be kept separate (all 300 series together etc.). The typical re-melt rate for stainless steel is between 60 and 85%.

The AISI (American Iron and Steel Institute) was the originator of the 300 and 400 series numbering system (i.e., Type 304 stainless steel). They also published a Stainless Steel products manual that listed these designations and the chemical analysis as well as most mechanical and physical properties of each individual grade. They are NOT specifications as such, just definitions of the individual...

There is a widely held view that stainless steel was discovered in 1913 by Sheffield metallurgist Harry Brearley. He was experimenting with different types of steel for weapons and noticed that a 13% Chromium steel had not corroded after several months. However, the picture is much more complex than this. For a comprehensive view read The Discovery of Stainless Steel.

Most decisions about which steel to use are based on a combination of the following factors:What is the corrosive environment? – Atmospheric, water, concentration of particular chemicals, chloride content, presence of acid.What is the temperature of operation? – High temperatures usually accelerate corrosion rates and therefore indicate a higher grade. Low temperatures will require a tough austeni...

There are many different types of surface finish on stainless steel. Some of these originate from the mill but many are applied later during processing, for example polished, brushed, blasted, etched and coloured finishes.The importance of surface finish in determining the corrosion resistance of the stainless steel surface cannot be overemphasised. A rough surface finish can effectively lower the...

How many types of stainless steel are there?Stainless steel is usually divided into 5 types:1.Ferritic – These steels are based on Chromium with small amounts of Carbon usually less than 0.10%. These steels have a similar microstructure to carbon and low alloy steels. They are usually limited in use to relatively thin sections due to lack of toughness in welds. However, where welding is not requir...

What forms of corrosion can occur in stainless steels?The most common forms of corrosion in stainless steel are:1.Pitting corrosion - The passive layer on stainless steel can be attacked by certain chemical species.
