Steel billets market value in 2021
Ferrites are inherently relatively magnetic and have lower thermal expansion and thermal conductivity than austenites, which means that they can conduct more heat than austenites in the same way. They are easier to cut and work with than austenite and are less prone to elastic return during cold forming. Ferrites have a higher yield strength than most austenites and are not subject to crack stress. For more information on the market value of steel billets in 2021, please visit our website.
Does billet steel rust?
There is evidence that steel contractors are offering inappropriately high construction and installation prices for stainless steel. This is sometimes due to the undesirable definition of excessive features by the design. For example, an architect uses a metal plate with special features for the components of a structure. To solve this problem, it is necessary to establish manufacturing and installation standards for various applications to ensure that the workforce and the quality of the consumables are appropriate for their use.

Rust is a common term used for iron corrosion. Rust causes disturbances in the mechanical properties of the metal, alters its chemical properties, and destroys the shape of the metal artistically and aesthetically. This is why many people in the field of design and selection of materials, try to avoid rust and its negative effects. Acid washing is the most popular method of iron rust. The well-known acid in this method is oxalic acid, which requires one to three tablespoons per gallon of water. The duration of immersion of iron parts in xalic acid varies from a few hours to several days and depends on the amount of rust and the size of the part. After the rust is completely removed, the iron parts should be thoroughly washed with water.
Sometimes you have to immerse the acid in sodium bicarbonate solution to make sure the acid is completely removed from the piece. Laser is one of the most recent removal of iron rust from rusted surfaces. The laser method can also remove instruments that operate at high temperatures, such as jet engines, from oxidation. The function of laser cleaning is that high power beams shine on the rusted area and eliminate rust. This method is very popular because it is high speed and does not use chemicals. It can also be used for small and soft parts.
Laser is used to remove rust and also to clean surfaces of aluminum, brass, semi-hard steel, copper, alloy steel, etc. Stainless steels are usually classified into five different classes based on chemical and metallurgical composition: Martensitic Ferritic Austenitic Duplex or ferritic-austenitic Precipitation-Hardening or PH In the following, we will explain each of them separately. Martensitic It is a group of stainless alloys, a triple alloy of iron, chromium and carbon, made to withstand corrosion and heat treatment. All martensite grades are nickel-free straight chrome steels. In other words, there is no nickel in this type of stainless steel and the hardening operation is done thermally.
The amount of chromium in this steel can be from 11 to 18% and also has a amount of 1% carbon. Strength, hardness and fatigue resistance are high in this type of stainless steel. It has a good level of flexibility and strength, but has moderate resistance to corrosion; In general, compared to other types of stainless steels, they have less resistance to corrosion, are magnetic, and have low weldability and ductility. Martensitic stainless steel is commonly used to make valves, springs, spoons and forks.
Ferritic In general, ferritic steels have a higher amount of chromium than martensitic steels, and normally the percentage of chromium is between 11 and 30% by weight. But the percentage of nickel is either very low or without nickel. The crystal structure of this type of steel is Bcc and these steels are magnetic but are not heat resistant. These steels are commonly used in non-structural applications that require high corrosion resistance. Ferrite stainless steels have good thermal and corrosion resistance, but in particular they have a high resistance to chloride. However, mechanical properties such as toughness at lower temperatures are lower than in ferritic stainless steels.
Applications of this type of stainless steel include:
- car exhaust
- cooking utensils and home appliances
