Q235B steel introduction

Q235B is a kind of ordinary carbon structural steel widely used in China, belonging to the Q235 series steel, often used in construction, Bridges, ships and machinery manufacturing and other fields. The "Q" in its name represents the yield point, the "235" indicates the minimum yield strength of 235 MPa, and the "B" indicates its quality grade and has good comprehensive performance. Q235B steel is known for its good plasticity, toughness and weldability, and can usually be used directly without heat treatment, belonging to the category of low carbon steel.

Q235B can be made into steel plate, steel rod, Angle steel, channel steel and other forms, thickness or diameter generally varies from a few millimeters to hundreds of millimeters according to the use, the specific size can be customized according to demand. Its chemical composition mainly includes carbon (C≤0.20%), silicon (Si≤0.35%), manganese (Mn≤1.4%), sulfur (S≤0.045%), phosphorus (P≤0.045%), and the content of these elements ensures the stability of its mechanical properties.

Q235B is usually delivered in hot rolled condition and the surface can be painted, galvanized or coated as required to enhance corrosion resistance. In practical applications, its low cost and ease of processing make it an ideal choice in the engineering and c
construction industry, especially for structural parts with moderate strength requirements
