51 steel pipe network for everyone to distinguish Q195, Q215, Q235, Q255 and Q275

The latest offer for 51 steel pipe includes grades such as Q195, Q215, Q235, Q255, and Q275. These steel grades are denoted by a combination of letters and numbers, where "Q" stands for the yield point, followed by the yield strength value in MPa, and then additional symbols indicating quality (A, B, C, D) and the deoxidation method. This systematic naming convention helps identify the material's properties and suitability for different applications. From a chemical composition perspective, these low-carbon steel grades—Q195, Q215, Q235, Q255, and Q275—vary in their carbon and manganese content. The higher the carbon and manganese levels, the greater the stability in terms of plasticity and strength. When it comes to mechanical properties, these grades represent the yield strength of steel with a thickness of up to 16mm. Their tensile strengths range from 315–430 MPa, 335–450 MPa, 375–500 MPa, 410–550 MPa, and 490–630 MPa respectively. The elongation values are also different: 33%, 31%, 26%, 24%, and 20% respectively, which indicates how ductile each grade is. Understanding these differences is crucial when recommending steel products to customers. It’s important to advise them to select the appropriate steel grade based on the specific requirements of their application. Choosing the wrong material could negatively impact the performance and durability of the final product.
