1. Q: What is the yield strength of Q235B?
A: The minimum yield strength (ReH) for Q235B with thickness/diameter ≤16mm is 235 MPa. For thicknesses >16-40mm, it's 225 MPa.
2. Q: What is the yield strength of A106B?
A: The minimum specified yield strength for A106B is 240 MPa (35,000 psi).
3. Q: What is the tensile strength range for Q235B?
A: Approximately 375-500 MPa.
4. Q: What is the tensile strength requirement for A106B?
A: The minimum tensile strength is 415 MPa (60,000 psi).
5. Q: How do elongation properties compare?
A: Both have good ductility. A106B typically requires a minimum elongation of 20-22% (on a standard specimen), while Q235B's requirement varies with specimen type but is generally comparable or slightly higher for thinner sections.
