Steel is one of the most important and widely used engineering materials in the world, which is used in various industries due to its high strength, capability and long durability. This vital material is generally divided into two main categories building steel and industrial steel , each with different features, compounds and applications. Transboundary Trading as one of the top iron and steel suppliers in the Tehran market, offers the types of steel needed for construction and industrial projects with the best quality and price.
The definition of steel and its main composition
steel is a combination of iron and carbon whose carbon content usually varies from 0.5 % to 5 %. Adding alloying elements such as chromium, nickel, manganese, vanadium and molybdenum can improve the properties of steel.
- Basic composition: iron (Fe) + carbon ©
- Alloy elements: for greater resistance, stainlessness or hardness
What is building steel?
Construction steel is a type of steel used in the construction of structures, bridges, buildings and construction projects. This steel must have high tensile strength and adequate plague due to its high pressure and load tolerance.
The main features of construction steel
- Mechanical Resistance appropriate
- High welding capability
- Live and dead load tolerance
- durability against weather conditions
What is Industrial Steel?
Industrial Steel is a type of steel used in the production of machinery, industrial tools, factory equipment and special parts. This steel often has specific alloy compounds and special thermal processes to have the desired mechanical and chemical properties.
The main features of industrial steel
- High thermal and abrasion resistance
- Hardness controllable with heat treatment
- accurate machinery capability
- Suitable for use in oil, gas, petrochemical and automotive industries
