Mechanical properties of some grades of stainless steel
Are you interested in the mechanical properties of some types of stainless steels from the supplier AvecGlob? Here you will find the necessary information on this topic.
General information
The properties of stainless steel are determined by its chemical composition and microstructure. A characteristic feature of the chemical composition of stainless steels is a high percentage of chromium, which can reach 18… 20%. Chrome gives stainless steels increased strength and hardness, and in combination with nickel — also a sufficient plasticity.
Deformation temperature
According to its microstructure, stainless steels can be ferritic and austenitic grade, and also combined. Special types are duplex steel, as well as steel. capable of precipitation hardening.
Austenitic varieties retain high strength at elevated temperatures. This is especially true for varieties containing high levels of chromium and / or a high content of silicon, nitrogen and rare earth elements. Some high-chromium ferritic grades can also exhibit high strength.
The high chromium content of stainless steel also helps to resist molding at elevated temperatures.
Stainless steel plasticity
During the tensile test, the tensile property is usually determined by the relative elongation. Extension of austenitic stainless steels is quite large. High plasticity and high rate of hardening allows plastic deformation of austenitic stainless steel with the realization of high values of the degree of deformation.
Supplier — AvekGlob Company — offers to purchase a range of rolled products, made from different grades of stainless steels. Products can be bought at a price formed on the basis of European and world standards. Implementation is possible in bulk and retail, for regular customers, a flexible system of discounts operates.
High strength
Compared to soft steels, stainless steel tends to have a higher tensile strength. Duplex stainless steel has a higher tensile strength than austenitic steels.
Magnetic properties of stainless steels
Austenitic grades are usually not magnetic, although this can be induced by cold treatment. With the increase in the percentage of nickel, the magnetic properties of stainless steels weaken.
All other brands are magnetic.
Cryogenic resistance
Cryogenic stability is measured by ductility or viscosity at temperatures below zero. At cryogenic temperatures, the tensile strength of austenitic stainless steel is significantly higher than at ambient temperatures. They also maintain excellent strength.
Ferritic, martensitic and precipitation hardening steels should not be used at zero temperatures. The strength of these varieties decreases significantly at low temperatures. In some cases, this drop occurs close to room temperature.
Hardening of stainless steel
Dispersion hardening stainless steel grades have the advantage that a significant increase in the strength of the metal can be achieved simply by cold working. A combination of cold working and annealing steps can be used to impart a certain strength to the manufactured component.
