Czech General Structural Steel And Low Alloy Steel
The Czech Republic has a rich metalworking heritage and many of those traditional skills are still in practice today, especially when it comes to metalworking and welding of steel structures. General structural steel and low-alloy steel grades are widely used in the Czech Republic, particularly for commercial and industrial projects. In this article we take a closer look at the common steel grades used in Czech metalworking and welding projects.
General Structural Steel
General structural steel is a type of steel designed to be used for beams, columns, girders and other components of a structure or building. The common types of general structural steel used in the Czech Republic today for metalworking and welding projects include S235J2, S355J2 and S355J2.
S235J2
S235J2 is a general structural steel grade commonly used in the Czech Republic for metalworking and welding projects. Its features a tensile strength range of 360-510N/mm2 and a yield strength limit of +350N/mm2. S235J2 is also known for its good fatigue resistance, weldability and formability. It is often used in applications such as bridges and load-bearing structures.
S355J2
S355J2 is another common structural steel grade used in Czech metalworking and welding projects. It features a tensile strength range of 470-630N/mm2 and a yield strength limit of +355N/mm2. The good fatigue resistance and weldability of S355J2 make it an ideal choice for metalworking and welding projects. It is often used in applications such as offshore structures, ships and cranes.
S355J2C
S355J2C is a variation of the S355J2 grade that is crafted specifically for cold forming processes. It has a higher lower yield strength (460N/mm2 when cold forming) and is often used in applications such as welded pipes and frames.
Low-Alloy Steel
Low-alloy steel grades are commonly used in Czech metalworking and welding projects, particularly for components that require higher tensile strength and greater corrosion resistance. The most common low-alloy steel grades used in the Czech Republic today are P355N, S420NL and S460N.
P355N
P355N is a low-alloy steel widely used in the Czech Republic for metalworking and welding projects. It features a tensile strength range of 490-620N/mm2 and a yield strength limit of +355N/mm2. It possesses good weldability and formability, making it an ideal choice for metalworking and welding projects where strength and corrosion resistance are a priority.
S420NL
S420NL is another type of low-alloy steel grade popular in the Czech Republic for metalworking and welding projects. It features a tensile strength range of 500-670N/mm2 and a yield strength limit of +420N/mm2. It is known for its excellent weldability and formability, making it an ideal choice for applications that require higher tensile strength such as bridges and offshore structures.
S460N
S460N is a low-alloy steel grade often used in Czech metalworking and welding projects. It features a tensile strength range of 550-730N/mm2 and a yield strength limit of +460N/mm2. It is known for its excellent weldability and formability, making it an ideal choice for applications that require higher tensile strength and greater corrosion resistance such as shipbuilding and steel beams.
Conclusion
General structural steel and low-alloy steel grades are widely used in the Czech Republic for metalworking and welding projects. The most common grades used today are S235J2, S355J2, S355J2C, P355N, S420NL and S460N. Each of these grades possess different characteristics that make them ideal for specific applications where strength, weldability and formability are key considerations.
