Q235B/Q355B Galvanized angle iron
Q235B and Q355B galvanized angle steel are two common steel materials for construction and structure. They have some differences in chemical composition, mechanical properties, and uses.
Q235B and Q355B galvanized angle steel are two common steel materials for construction and structure. They have some differences in chemical composition, mechanical properties, and uses.
Q235B steel plate has high yield strength and tensile strength, with a yield strength of 235MPa and a tensile strength between 370 and 500MPa. It can withstand large loads and provide a solid structural foundation for angle steel, allowing it to withstand certain pressure and tension during use. Q235B is easy to cast and weld, which is conducive to the manufacture of angle steels of various shapes, and during the processing and assembly process, it is easy to connect with other parts by welding and other methods. In addition, it also has good plasticity and is easy to carry out processes such as cutting, bending, and stamping.
Q235B seamless pipe is a seamless pipe made of carbon structural steel defined in accordance with the Chinese national standard GB/T700. It has certain strength and good processing performance at room temperature, good surface quality, and can meet the use requirements of general engineering.
It is easy to cast and weld, which is conducive to manufacturing parts of various shapes and processing and assembly. It also has good plasticity, which is convenient for cutting, bending, stamping and other processes. It can withstand various harsh climate and environmental conditions and has certain corrosion resistance.
It has excellent castability and weldability, is easy to cast and weld, and is conducive to the manufacture of parts of various shapes and processing and assembly. It also has good plasticity and is easy to cut, bend, stamp and other processes. Due to its low carbon content, the welding process window is wide and it is suitable for most conventional welding methods, such as manual arc welding, gas shielded welding, etc. It is also easy to perform deformation processing such as cold bending and stamping, and is suitable for making special-shaped components.
SPHC has added special elements (P, Cu, C, etc.) and has good corrosion resistance and atmospheric corrosion resistance. SPHD has a thickness of 1.2 - 8mm and a width of less than 600mm, which is called narrow strip steel, and those over 600mm are wide strip steel. Its carbon content is slightly higher than that of cold-rolled steel plates. When the components are not much different, its density is the same as that of cold-rolled steel plates. SPHE is made by pressing low-carbon steel and ordinary alloy steel at high temperature.
