Automotive industry: precision and reliability with plates cut on CNC
The use of CNC cut plates in the automotive industry is appreciated for its precision and reliability. Sheet metal plates cut on CNC play an essential role in the manufacture and assembly of vehicles. They are used in key components that require precision, strength and durability. Bodywork components Plates cut on CNC are used for: […]
Carbon steels
Carbon steel contains traces of alloying elements, iron and carbon. They represent 90% of the total steel production. They can be classified, in turn, according to the carbon content: a) Steels with low carbon content, up to 0.3% carbon. The largest category of this class of steel is made up of flat rolled products (sheets […]
Thermal galvanization and electro-galvanization
Steel corrosion represents the partial or total destruction of the material under the action of various environmental factors. In order to extend the life of these materials, anti-corrosion protection is carried out. The most frequently used processes for this are thermal galvanizing and electro-galvanizing. What are the differences between thermal galvanizing and electro-galvanizing Thermal galvanizing […]
Tempering of steel
Steel tempering is a thermal treatment that consists in heating it above the temperature of the phase transformations, maintaining it at this temperature to complete all the phase transformations and cooling it at high speed. In the quenching treatment, besides the cooling speed factor, the alloying elements also play an important role: nickel, chromium, molybdenum, […]
Types and differences between steels – OL 37 and OL 52
In order to correctly execute a construction, it is necessary to know the types and the differences between the steels. In metal constructions, steels are classified according to the steel brand (tensile strength). The most frequently used steels, in Romania, for the realization of metal constructions are the following: OL 37, OL 44, OL 52. […]
What are the differences between laminated corner – embossed corner
It is very important to know what the differences are between a laminated corner and an embossed corner, before carrying out a project. These two angles are metallurgical products made of steel, only they are manufactured by two totally different methods. A laminated cornice is made by the hot or cold lamination process. It has […]
Hot rolling vs. cold rolling
The lamination process is carried out by two methods – hot or cold. And it is done by forcing the material (steel) through the gap between two cylinders. The two types of lamination, hot and cold, differ in three major aspects: lamination temperature, thickness and material properties. Types of lamination – descriptions and differences Hot […]
Steel ductility
In general, the steel used in modern constructions is a material with high ductility. It is resistant to both compression and stretching. The ductility of steel represents its ability to deform plastically without breaking. This characteristic allows the steel to be drawn or rolled to obtain long and thin products. The steel is transformed through […]
The Empire State Building and the Eiffel Tower are metallic steel constructions
The Empire State Building and the Eiffel Tower are two metallic steel constructions with impressive dimensions and a spectacular design. They are known all over the world, admired and even become extraordinary backgrounds for famous movies. Beyond these „glamour” aspects, a fact less known to the general public but, of course, essential, is that, for […]
The first suspension bridge with steel cables – the famous Brooklyn Bridge
The Brooklyn Bridge is the oldest steel cable suspension bridge built in the United States of America. It connects two important neighborhoods of New York: Manhattan and Brooklyn. At the beginning of the 19th century, Brooklyn was nowhere near what it looks like today. We can say, rather, that it resembles, without exaggerating, a rural […]
