Based on the main business of iron and steel, we are committed to producing high-quality, green and efficient steel products. The main steel products are medium and S550MC high strength steel equivalent heavy plate, hot rolled coil, section steel, steel tube, etc., which are widely used in automobile, oil, railway, bridge, construction, electricity, transportation, machinery, shipbuilding and other important fields. Our steel products are exported s550mc high strength steel equivalent to Indonesia, Bangladesh, Myanmar, Iran, Brazil, Mexico, UAE, Iraq, etc Egypt, Mozambique, Ukraine and other dozens of countries and regions.

Do you know the thickness range of BBN Steel's hydrogen sulfide resistant steel plate? The s550mc high strength steel equivalent product thickness is between 8-180mm. q345rHIC steel and Q345RR-HIC test environment: A solution HIC steel (HIC-A) and B solution HIC steel (HIC-B) Q345RHIC and Q345RR-HIC test items: tensile, bending, thickness direction properties, grain size, Brinell Hardness, ultrasonic flaw detection, HIC test, impact test, high temperature tensile test, SSCC test, melting analysis, finished product analysis.

Q345B material is a low carbon alloy steel grade with good overall performance, low temperature performance, cold stamping performance, welding performance and machinability. Q345 serues steel is widely used in bridges, vehicles, ships, buildings, pressure vessels. Q represents the yield of this material, and the number 345 refers to the yield value of this material, which is around 345MPa. As the thickness of the material increases, its yield value decreases.

The density of wear-resistant plate is higher than that of some materials, s550mc high strength steel equivalent, which makes its hardness larger. The density of steel for wear-resistant plate is 7.85kg/dm cubic. After quenching, martensite structure is obtained and tempered at 450-600℃, or 350-600℃ after tempering at 650℃. Or after tempering at 650℃ and heating at 350-650℃ for a long time, the wear-resistant plate will be embrittled. If the brittle wear-resistant plate is reheated to 650℃ and then cooled quickly, the toughness can be restored, so it is also called reversible temper brittleness. High temperature temper brittleness is the increase of the transition temperature from toughness to brittleness.
