Carbon steel plate is a kind of low carbon steel plate, it is very soft, easy to shape processing, A36 carbon structural steel plate under pressure performance, high durability, and the price is very cheap is the most widely used hot-rolled steel products in the construction industry. ASTM A36 final product has a rough surface and is easy to machine. for further processing.
Carbon steel coil from finishing the last hot steel strip mill out through laminar flow cooling to the set temperature, which consists of the winder coil, steel coil after cooling, according to the different needs of users, with different finishing line (flat, straightening, transverse or longitudinal cutting, inspection, weighing, packaging and logo, etc.) and become a steel plate, flat roll and longitudinal cutting steel strip products.
Q245b is an ordinary carbon structural steel with a yield strength of 245 MPa, which belongs to semi-killed steel.
The carbon content is about 0.05% to 0.70%, and some can be as high as 0.90%. It can be divided into two types: ordinary carbon structural steel and high-quality carbon structural steel. There are many uses and a large amount of use. It is mainly used in railways, bridges, and various construction projects to manufacture various metal components that bear static loads, as well as unimportant mechanical parts that do not require heat treatment and general weldments.
Grade:Q195, Q215 ,Q235, Q345,A36,SS400,10#,45#,ST35,ST52,16MN Standard: AISI ASTM JIS SUS DIN EN and GB Size: According to the customer’s requests Technique: Cold Rolled and Hot Rolled Certifications: ISO 9001,SGS,BV
After heat treatment, the mechanical properties of the product are more perfect, and the compressive strength can reach 1100-1300mpa (160-190ksi). This grade cannot be used at temperatures higher than 300 ℃ (570f) or very low temperatures. It has good corrosion resistance to atmosphere and diluted acid or salt. Its corrosion resistance is the same as that of 304 and 430.
Welded steel pipe, also known as welded pipe, is made of steel plate or strip after crimping forming welded steel pipe, general length 6 meters. Welded steel pipe production process is simple, high production efficiency, variety of specifications, less investment in equipment, but the general strength is lower than seamless steel pipe.
