Q235 is a kind of carbon structural steel, which is commonly used in the production of various metal products and components. These two Q235C and Q235D are different in some respects.
Q235C is usually rolled into steel plates, shaped steel and profile steel, which usually used to build workshop, bridge, vessels and so on. The latest standard of steel Q235 is GB/T 700 2006, which is replaced by GB/T 700-2005. Steel Grade Q235C also can be made as Q235C mild steel. The minimum yield strength of this steel shall be 235Mpa.
Q235D, on the other hand, is usually rolled into steel plates, formed steel and section steel, used for various types of construction. The latest standard of steel Q235D is GB/T 700 2006, which is replaced by GB/T 700-2005. Steel Grade Q235D also can be made as Q235D mild steel. The minimum yield strength for this steel shall be not less than 235Mpa.
For structural steel, Q235C and Q235D are mainly used in industrial and civil construction, such as roof structure, bridge, column, beam, etc. Generally speaking, Q235C is suitable for the manufacture of structural components such as columns, beams, and other structural frames, while Q235D is mainly used for hot rolled plate and strip parts.
In addition, Q235C and Q235D can be used to make steel production containers, bridges, ships, vehicles, and construction and many other structural parts, these two materials also can be used for the production of various kinds of mechanical parts. For example, Q235C can be used to sculpt tools, screws, nuts, bolts, and other industrial components, Q235D is mainly used for the production of precision parts, mechanical parts and components.
In short, due to their different properties, Q235C and Q235D are often used in different purpose. Q235C is generally used in the manufacture of structural parts, while Q235D usually used for hot rolling and production of mechanical parts. Both can also be used to make containers, bridges, ships, vehicles and other structures, and are widely used in industrial and civil engineering building.
