Last Updated on July 1, by Marsh Fasteners. These fasteners, which also include theHQ, andare characterized by multiple variables and grades with a close chemical composition. There is very little overall difference in corrosion resistance among these series types.
They do, however, feature slight differences when it comes to their chemical composition, making some grades more resistant than others against particular chemicals or atmospheres. This fastener series has superior corrosion resistance and is generally non-magnetic.
It is also harden-able by cold working. This gives these fasteners much better levels of resistance to corrosion than the series.
These fasteners are ideal of use where there is exposure to chemicals and other types of corrosive products such as chloride which tends to cause pitting. This series offers superior performance when products are to be exposed to sea water and is resistant how to write business plan free corrosion in sulphuric acid compounds.
These fasteners are thus best used in projects where there is likely to be exposure to direct salt spray and a variety of harsh chemicals.

Sep 27, · Type , with its chromium-nickel content and low carbon, is the most versatile and widely used of the austenitic stainless steels. Its alloys are all modifications of the 18% chromium, 8% nickel austenitic alloy. Type proves to be resistant to oxidation, corrosion, and durability. Jan 12, · Type , with its chromium-nickel content and low carbon, is the most versatile and widely used of the austenitic stainless steels. Its alloys are all modifications of the 18% chromium, 8% nickel austenitic alloy. Type proves to be resistant to oxidation, corrosion, and durability. As the most widely used of all stainless steel, stainless steel is most notably present in industrial applications and kitchen equipment. It is a highly heat-resistant grade, and offers good corrosion resistance to many chemical corrodents, as well as industrial atmospheres.
Type is non-magnetic under annealing conditions, but after cold working such as stamping, stretching, bending, rolling , part of the austenite structure may be converted into martensite and therefore weakly magnetic. AISI has good resistance to atmospheric corrosion and oxidation.
The high nickel-chromium alloy content gives it excellent corrosion resistance and is widely used in the food industry as a standard food grade stainless steel.
There are several variants of grade stainless steel, such as ultra-low-carbon version type L , nitrogen-containing version N, H with improved creep performance, and type with higher carbon content.
The addition of molybdenum can enhance the resistance to pitting and crevice corrosion caused by chloride. Therefore, SS is widely used in marine applications. The following tables give AISI stainless steel properties and specifications datasheet including chemical composition, physical and mechanical properties, heat treatment, corrosion resistance, machinability and machining, welding, etc.
Type grade stainless steel physical properties are listed in the table below such as density, melting point, specific heat, electrical resistivity, elastic modulus modulus of elasticity , thermal conductivity, and coefficient of thermal expansion CTE. AISI stainless steel mechanical properties are given in the datasheet below including tensile strength, yield strength, elongation, reduction in area, Brinell and Rockwell hardness, etc.
The following contents give AISI grade stainless steel heat treatment temperature of including annealing, forging, stress relief, etc. Conventional austenite such as AISI stainless steel cannot be hardened by heat treatment, because they will not change their crystal lattice structure when heated, so they can only be hardened by cold working. Cold working will transform a part of austenite into martensite. As the amount of martensite in the steel increases, its strength increases and its plasticity decreases.
The reason why stainless steel does not rust is because the Cr and Fe in it are oxidized to form a dense passive film to prevent further corrosion. AISI stainless steel has excellent corrosion resistance in mild atmosphere and fresh water, and even the surface will not rust. Type stainless steel has excellent weldability and does not require preheating.
Generally, post-weld heat treatment is not required, unless large cross-sections are welded, or weld decay may occor. To prevent weld decay, please refer to heat treatment-stress relief, or recommend the use of ultra-low carbon stainless steel such as L, or stabilized stainless steel , AISI stainless steel is widely used in the food industry, home appliances and consumer electronics, medical equipment, architectural decoration, hardware tools, automotive industry, petrochemical, water treatment plants, aerospace, etc.
Chemical Composition Type stainless steel chemical composition is listed in the following table. See notes Stress-relieving for structural soundness Where severe manufacturing stress coupled with high service load may cause cracking.
However, in order to provide the best stress relief treatment, it is recommended to use a stabilized or ultra-low carbon grade. Severe stress corrosion application: stabilized such as , , or ultra-low carbon grade such as L, L is recommended.
Hardening Conventional austenite such as AISI stainless steel cannot be hardened by heat treatment, because they will not change their crystal lattice structure when heated, so they can only be hardened by cold working.
Corrosion Resistance The reason why stainless steel does not rust is because the Cr and Fe in it are oxidized to form a dense passive film to prevent further corrosion.
Typical Applications AISI stainless steel is widely used in the food industry, home appliances and consumer electronics, medical equipment, architectural decoration, hardware tools, automotive industry, petrochemical, water treatment plants, aerospace, etc. The following list shows typical uses in various industries: Food industry: tableware and kitchenware such as stainless steel woks, steamers, pans, forks, chopsticks, baking trays, bbq grills, dairy containers, sterilization baskets.
