Q235 vs ASTM A36, S235, SS400 and E250 Steel. The following tables show Q235 steel vs A36, SS400, S235JR and E250 steel, they are similar in chemical composition, mechanical properties, and all belong to carbon structural steels.

Jaway Steel is a fully based on stainless steel metal products suppliers. It provides all kinds of grades and types Whats the difference of Q235A, Q235B, Q235C, Q235D and Q235E ? with affordable price,high quality and fast shipping in world wide.

When the steel of Q235 is polished with grinding wheels, the sparks flying are rounded particles and dark colors. And the spark of Q345 is bifurcated, the color is bright. Also, according to the color difference between the two steel shearing surfaces, it is possible to distinguish between two types of steel.

Q235 Steel (Q235A Q235B Q235C Q235D) Q235 steel is a Chinese GB standard plain carbon structural steel, and divided into 4 quality gradesQ235A, Q235B, Q235C and Q235D, material density is 7.85 g/cm3, tensile strength is from 370 to 500 MPa; yield strength is 235 MPa (data are for steel bar or steel plate diameter 16mm).The latest standard of steel Q235 is GB/T 700 2006.
