Mechanical properties of some grades of stainless steel
Are you interested in the mechanical properties 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 most clearly compared with the standard soft low-carbon steel. Although stainless steel has a wide range of properties, in general, compared to mild steel, stainless steel has:
High corrosion resistance
Higher cryogenic viscosity
Higher rate of hardening
Higher Strength
High plasticity
Higher hardness
More attractive appearance.
Corrosion resistance of stainless steel
All stainless steel is an iron-based alloy that contains at least 10.5% chromium. Chromium in the composition of stainless steels forms a self-healing protective transparent oxide layer.
This oxide layer provides corrosion resistance of stainless steel. The self-restoring nature of the oxide layer means that the corrosion resistance remains unchanged regardless of the manufacturing methods. Even if the surface of the material is cut or damaged, its corrosion resistance will not deteriorate.
Conversely, conventional carbon steels can be protected against corrosion only by staining or other coatings, such as galvanizing.
Corrosion of different grades of stainless steel will differ in different conditions. Suitable estimates will depend on the conditions of service.
Even trace amounts of some elements can significantly change the corrosion resistance. Chlorides, in particular, can adversely affect the corrosion resistance of stainless steel.
High-strength metals containing molybdenum and nickel are the most resistant to corrosion.

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.
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.
A typical example of this is the production of wire. The wire that will be used as springs will cure to work with a certain tensile strength. If the same stainless steel grade should have increased flexibility, the material is annealed. as a result of which the hardness is reduced, and the plasticity increases.
