Stainless steel or, as it is often called by the people, stainless steel is a reliable high-strength material that is used in many industries. It is not afraid of high humidity, is resistant to rust and corrosion, withstands a wide temperature range.
Stainless steel today is presented in a wide range. Below we will figure out what types the material is divided into and what advantages it has.
Why use stainless steel
Stainless steel products are products based on an iron alloy with additional substances that strengthen and improve the properties of finished sheets. Additional application of a protective layer: chromium or nickel creates a film that can prevent the damaging effects of ultraviolet radiation, frost and high humidity.
Among the main advantages of the material:
- Resistant to high humidity. Corrosion and rust do not appear on such products.
- Increased resistance to aggressive environments. Rolled metal can come into contact with chemical compounds: acids, alkali, etc.
- Compliance with all norms and requirements of fire safety. The material does not support combustion.
- A huge selection of products that differ from each other in composition, production technology, shape of products.
Composition and production technology of stainless steel
Types of stainless steel are distinguished mainly based on the composition of the alloy. Manufacturers offer sheets today:
- From austenitic steel. The most popular option, characterized by resistance to corrosion and elevated temperatures. Contains nickel in the composition in a percentage of up to 7%.
- Based on ferritic steel. Chromium is added to such an alloy, which increases the resistance of the finished product to increased mechanical stress. The percentage of chromium ranges from 10% to 20%.
- Martensitic. Stainless steel products of this type are the most resistant and durable, withstand contact with acids. Also available in the composition of chromium up to 18%.
By type of production, the following types of stainless steel are distinguished :
- Hot rolled . A budget and less durable option that requires special processing for use.
- Cold rollers. The most stable and attractive appearance, do not have defects on the surface.
What products are made from stainless steel
If in the phrase "stainless steel" the first word means the material from which the product is made, then the second one indicates the category of products. That is, it is finished productsobtained in the process of running metal. Manufacturers today offer its types:
- Pipes. They differ in wall thickness and diameter. They can be used in construction work, at industrial facilities, in the arrangement of supports, parapets, and so on.
- Flat rolled metal. Most often, these are products that can have a different shape: round, square, hexagon. There are also small flat items. This category also includes stainless steel. Such products are most relevant in the field of construction.
- Sheets. Can be produced by hot or cold rolling. Sold in different sizes and shades, they can be glossy and matte. They have a wide scope: from construction work to room decor.
