S235JRG2 steel plate is a mild steel plate commonly used in construction and machinery manufacturing. The following are some knowledge points about S235JRG2 steel plate:
S235JRG2 steel plate is a non-alloy structural steel defined in European standard EN
HSLA Grade 50 steel plate (High Strength and Low Alloy) is a low-alloy, high-strength steel used in shipbuilding, bridge construction, gas pipelines and automotive manufacturing. Here are some knowledge points related to HSLA Grade 50 steel plate:
The ch
In the national standard, the P and S requirements of Q345E structural steel are not very strict, but because the mechanical properties required by the user are higher than the national standard, the impact test is conducted at -40 ℃, so we strengthen the
Low alloy structure and high strength steel Q345E steel can be used in the part of railway vehicle and meet the requirements of speed increase of railway vehicle in our country. The customer orders to our company according to GB/T1591-2008 standard, and p
Mechanical test results of hot coil production of weathering steel SPA-H before and after composition optimization. Through the composition design of low Ni and high Ti, the mechanical properties of the steel SPA-H, such as tensile strength, yield strengt
More than 90% of the world's containers are produced in China. In the past two years, there has been a significant increase in the import and export of containers. Hot-rolled weathering steel for container production has a good market. The main weatherin
42CrMo4 steel is the main material for manufacturing wind power fasteners, and its mechanical properties can be significantly improved by conditioning treatment. At present, the commonly used tempering heating equipment for wind power fasteners includes t
Laser welding has fast welding speed and low heat input rate, so that the heat-affected zone and deformation of CCS B marine steel plate are small. In foreign countries, laser welding technology has been successfully applied in industrial fields such as a
For the SM490YB test steel plate, in order to obtain uniform and fine ferrite and pearlite structure and appropriate hardness, and to obtain the required properties, the continuous cooling rate after normalizing should be controlled at 0.3-1.0 ℃/s.
For SM490YB steel plate, the normal structure is ferritic + pearlite, As the normalizing temperature increases from 900℃ to 940℃, the yield strength and tensile strength of SM490YB steel sheet decrease from 358 ~367 MPa to 334 ~340MPa, and the tensile str
