Carbon steel is defined as steel that has its properties mainly due to its carbon content and does not contain more than 0.5 percent of silicon and 1.5 percent of manganese. The plain carbon steels, which range from 0.06 percent carbon to 1.5 percent carbon, are divided into four types:

The imported product is a Carbon Manganese steel while locally produced tube is typically produced with low Carbon micro-alloyed steel. Thus the Q345 has a much higher Carbon Equivalent content close to the maximum recommended maximum value of 0.45.
Mechanical Properties. 1, Yield Strength. A yield strength or yield point is the material property defined as the stress at which a material begins to deform plastically. Prior to the yield point the material will deform elastically and will return to its original shape when the applied stress is removed, Yield strength of Q345B is 345 MegaPascals.
Mechanical Properties. The tensile strength of Q345B steel is rated at 470 to 630 MegaPascals (where mega is million) and a yield strength (where the material starts to thin and pull like taffy) at 345 MegaPascals. Like most steels of its grade, it suffers elongation before it pulls apart, typically at 20-21 percent of its initial length.
Q235 Steel Properties and Introduction Q235 steel is a Chinese GB standard plain carbon structural steel, and divided into 4 quality grades: Q235A, Q235B, Q235C and Q235D , material density is 7.85 g/cm3, tensile strength is from 370 to 500 MPa, and yield strength is 235 MPa (data are for steel bar or steel plate diameter 16mm).
If only compare the mechanical properties of these grades, it is found that the mechanical properties of A36 and high quality carbon structural steel 20# are quite similar to each other. Tensile strength of 20# steel is not less than 410, yield strength is not less than 245, and mechanical properties of A36 are about the same.
Q235B Included in 3 standards (China) Chemical composition C < 0.22 Si < 0.35 Mn < 1.4 P < 0.045 S < 0.045 Cr < 0.3 Ni < 0.3 Cu < 0.3 N < 0.008 As < 0.08 Fe Rest It's allowed to exceed N content up to 0.014% in finished products. On exceeding N for every 0.001% max P content reduces by 0.005%. F - unkilled steel Z - killed stee TZ - special , buy sm490a steel tube
It has come to the attention of the ASTPM that Grade Q345, a standard in China, Grade Q345 it is not equivalent to S355 in terms of mechanical properties in . Q345 Steel Equivalent - Alibaba.
