Q195 Carbon Steel Plate
Q195 carbon steel plate has collected generous disquisition enthusiasm as a basic designing material for its high malleability, strength and welding execution. It has numerous applications in everything from sheds to roofing and vehicle assiduity.
It has moderate tensile strength and good formability. This balance between strength and formability makes it ideal for making frameworks and supports.
Chemical composition
Q195 is a Chinese plain carbon structural steel grade, with a yield strength of 195 MPa and tensile strengths between 315 and 430 MPa. It has a material density of 7.85 g/cm3. This grade is commonly used in structural and general-purpose applications. It is not considered high-strength steel, but it is strong enough for most fabrication applications. It can be welded and bent without cracking, and it has good ductility.
The yield strength of Q195 steel indicates how much stress the material can withstand before it starts to deform permanently. This measure is often referred to as the yield point, and it is important Q195 carbon steel plate when designing structures or selecting materials. The chemical composition of this grade consists of mainly iron, with small amounts of manganese and silicon. It also contains traces of phosphorus, sulfur, and nitrogen.
Q195 steel is usually used in manufacturing wire rod and steel sheets. The former can be cold drawn into low-carbon steel wires, which are then made into black or galvanized iron wires, welded wire mesh, or wire fences; the latter can be cold and hot rolled into various forms, including roofing panels, decorative panels, packaging containers, iron drums, distribution boxes, and protective covers. It is also used to make steel pipes, anchor bolts, chimneys, roof slabs, rivets, ties, hooks, and brackets.
Mechanical properties
Q195 carbon structural steel is broadly utilized worldwide on account of its brilliant incorporated presentation in quality, versatility, weldability, and processability. It can be made into a wide assortment of steel items, including steel wire rod, dark or galvanized iron wire, binding wire, welded mesh, metal fence, and steel plates. It can likewise be utilized as material for steel pipes and tubes, as well as for steel angles.
It has excellent weldability, enabling it to be easily welded with standard processes. It also has good machinability, making it easy to be cut and shaped into desired shapes. Its low to medium hardness gives it a decent balance between strength and formability.
The yield strength of Q195 steel is 195 megapascals (MPa), which makes it suitable for various structural and industrial applications. However, it should be noted that there are differences in mechanical properties between this grade and its counterparts, such as Q235. Q235 has a higher manganese content than Q195, which helps it to offer better tensile strength. It also has a higher impact resistance than Q195, which is important for some applications. Additionally, it has a lower elongation than Q195. However, the differences between these grades are not significant enough to be a major concern. The most important thing is that you choose the right grade for your specific needs.
Electrical and thermal conductivity
Q195 carbon steel plate is a commonly used carbon structural grade in China. This steel grade has low carbon content, high tensile strength, and excellent welding properties. It is also easy to form and bend, making it ideal for industrial applications. While it is not inherently corrosion-resistant, it can be protected from oxidation through coatings or galvanizing.
Unlike other grades, Q195 carbon steel is not brittle and is very easy to process during manufacturing. This allows it to be welded and formed into complex shapes. The material is also highly ductile, meaning that it can be bent without breaking. It is also very resistant to corrosion, making it an excellent choice for industrial use.
Using field emission scanning electron microscopy (FESEM; ZEISS SUPRA55, Carl Zeiss) and X-ray diffraction analysis, we studied the surface morphology of Q195 carbon structural steel before and after electrolytic plasma processing (EPP). We found that EPP for 10 s successfully removed the surface scale from the sample. Furthermore, the tensile mechanical properties of the steel were improved after 40 s of EPP treatment. These results show that EPP can be a cost-effective method for improving the quality of carbon steel. It is therefore important to consider the processing and stamping performance of the material during the design stage. This will ensure that the final product meets the required quality and specifications.
Equivalent grades
Q195 carbon steel plate is a versatile and affordable material for manufacturing, fabrication, and repair projects. It is easy to weld, cut and form and can be used in a wide range of applications. Metals Depot carries hundreds of thicknesses and sizes of this popular hot rolled low carbon steel plate. You can shop online in our ready to ship precut and mill size steel plates or order custom cut-to-size pieces at wholesale prices.
The tensile strength of Q195 steel is 205 MPa, carbon steel plate suppliers while its yield strength is 195 MPa. This means that it is less ductile than other grades of carbon steel, but still has good cold-forming and welding properties. It is also able to handle moderate amounts of bending.
In general, Q195 is comparable to other carbon structural steels in terms of strength and flexibility. However, there may be other grades of steel with similar qualities, so it is always advisable to reference the appropriate standards and specifications when choosing a grade of steel for any specific application.
The specialized properties of Q195 steel make it suitable for a variety of different applications, such as manufacturing anchor bolts, ploughshares, chimneys, roof panels, rivets, low-carbon wires, thin plates, welded pipes, tie rods, hooks and brackets. Similarly, it can be used in manufacturing welded structures and automotive components.
