What Is Q195 Carbon Steel?
Q195 carbon steel is a type of Chinese plain carbon structural steel. Its yield strength is 195 MPa and its tensile strength is 315-430 MPa. It is an economical and durable material that can be used for a wide variety of applications.
In this study, EPP was applied to carbon steel to modify its surface morphology and mechanical properties. Both the elastic modulus and hardness of the metal decreased after 40 s EPP treatment.
Strength
Q195 carbon steel has a moderate yield strength of about 195 megapascals (MPa). This value indicates how much stress or load the steel can withstand before it deforms permanently, also known as its yield point. The lower the yield point, the more likely the steel is to break or dent. This grade of steel is suitable for a variety of structural applications that don’t require extreme strength.
The comprehensive mechanical properties of Q195, including strength, plasticity, toughness and weldability, make it U-shaped steel a versatile carbon structural steel. It can be used in a wide range of general applications, including manufacturing anchor bolts, ploughshares, chimneys, roof panels and rivets. It can also be cold or hot-rolled into low carbon steel wires, thin plates and welded pipes, as well as into tie rods, hooks, brackets and welded structures.
While the yield point of Q195 is similar to that of Q235, it possesses a slightly higher tensile strength and elongation. However, both grades are susceptible to corrosion when exposed to moisture and oxygen, so they must be treated with appropriate coatings or treated chemically to maintain their strength over time. This is especially true if the steel is buried in soil or water. Corrosion resistance is especially important for steel piping, since rusting can significantly decrease the efficiency of the pipe and even cause it to rupture.
Plasticity
Q195 is a type of carbon steel with good plasticity. This is because it has a low carbon content, which makes it easier to work with than other types of steel. It can also be formed into a variety of shapes without losing its strength. This quality makes it ideal for a wide range of applications, including building and industrial components.
The yield strength of Q195 steel is approximately 195 megapascals (MPa). This measurement indicates the amount of stress or load that the steel can withstand before it begins to deform permanently, which is known as its yield point. This moderate yield strength makes Q195 steel suitable for a variety of structural and industrial applications that do not require extremely high strength properties.
The tensile strength of Q195 steel is 315-430 MPa. This is comparable to the tensile strength of the American ASTM standard grade B (ss185) carbon steel. However, the lower carbon content of Q195 steel makes it better suited for cold-forming applications than the higher carbon content of ASTM standard grade B carbon steel.
Electrolytic plasma processing is a new surface treatment technology that uses an electric field to generate reactive gases on the surface of steel. This process improves the mechanical properties of steel, such as its ductility and toughness. In addition, it can increase the corrosion resistance of the material.
Weldability
Q195 is a Chinese plain carbon structural steel with yield strength 195 MPa and tensile strength 315-430 MPa. It is a widely used steel grade due to its comprehensive mechanical properties, including strength, plasticity, toughness, and weldability. It is often employed in manufacturing anchor bolts, ploughshares, chimneys, roof panels, rivets, low carbon steel wires, thin plates, welded pipes, and tie rods.
It is important to note that the weldability of Q195 is significantly improved by electrolytic plasma processing (EPP) treatment for 40 s. This improvement is attributed to the creation DX51D galvanized steel coil of a dense, compact zinc coating on the surface of the steel. This coating acts as an effective barrier against corrosion.
Q195 is comparable with a variety of other steel grades from different standards, including American ASTM A36, Chinese GB/T welded mesh and metal fence, Vietnamese SS400, German DIN St33, and British BS 400. These materials share similar mechanical properties and are often substituted for each other. This is because of their balanced properties, which provide good formability and weldability without sacrificing tensile strength. For this reason, they are ideal for many industrial applications. The differences between these steel grades lie in their strength and elongation levels, which make them suitable for different applications. For example, the higher strength of Q235 makes it more suitable for applications that require greater strength, while Q195 is better suited for applications where formability and weldability are more important than strength.
Corrosion Resistance
Q195 carbon steel is a type of steel that is used in heavy-duty industrial settings, like construction sites and oil fields. It is resistant to shocks and vibrations, making it a cost-effective option for many applications. Its strength and longevity also make it an attractive choice for industrial settings that require a high level of durability.
Like most carbon-based materials, Q195 steel is susceptible to corrosion when exposed to moisture and oxygen. It must be properly sealed and coated to protect it from corrosion. However, if these measures are not taken, the steel will quickly rust and become brittle.
In order to test the effect of EPP on the surface mechanical properties of the sample, elastic modulus and hardness were tested before and after EPP treatment for 40 s. The results showed that the EPP process impacted the surface of the steel, increasing its mechanical properties and making it more durable.
