What are the factors influencing the lamellar tearing of Z-direction S420ML grade equivalent

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 S420ML grade 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 S420ML grade equivalent to Indonesia, Bangladesh, Myanmar, Iran, Brazil, Mexico, UAE, Iraq, etc Egypt, Mozambique, Ukraine and other dozens of countries and regions.

The main component of S420ML grade equivalent manganese plate is manganese, which is a relatively powerful element type, and plays a more important role in long-term development and continuous use. The main characteristics of manganese plates are high hardness and high strength. For general manganese plates, it is necessary to enhance the compressive capacity of manganese steel plates and various basic corrosion resistance capabilities. For common manganese plates, pay attention to use, choose good specifications and classifications, thus the use value of manganese plates will be better.

For Q345B steel plate, Q stands for the yield of Q345B material. The 345 at the back refers to the yield value of Q345B material, which is about 345MPa. The yield value will decrease with the increase of Q345B steel plate thickness. Q345B steel plate has good comprehensive performance, low temperature performance, cold stamping performance, welding performance and machinability. It S420ML grade equivalent is widely used in bridges, vehicles, ships, buildings, pressure vessels, etc.

The allowable temperature of S420ML grade equivalent, boiler steel is mainly determined by strength condition. Different steels have different mechanical properties and high temperature properties. Even for the same kind of steel, the tensile strength, yield strength and rupture strength vary greatly with the working temperature, and decrease with the increase of working temperature. In order to ensure the safety of S420ML grade equivalent work, the actual stress of S420ML grade equivalent under the working temperature should be less than the allowable stress determined by the tensile strength, yield limit and permanent strength of S420ML grade equivalent under the temperature.

Chemical composition of Q420 steel: C ≤ 0.20, Si ≤ 0.50, Mn ≤ 1.70, P ≤ 0.035, S ≤ 0.035, Nb ≤ 0.07, V ≤ 0.20, Ti ≤ 0.20, Cr ≤ 0.30, Ni ≤ 0.80, Cu ≤ 0.30, N ≤ 0.015, Mo ≤ 0.20. The mechanical properties of Q420 steel are: yield strength ≥ 340 MPa, tensile strength 500-680 MPa, elongation after fracture ≥ 18%, impact energy 34J. S420ML grade equivalent, Q420 steel has good mechanical properties and weldability, good cold and hot workability. Q420 steel is mainly used for manufacturing mining machinery, heavy vehicles, ships, bridges, medium and high pressure boilers, vessels and other large welding and structural parts.
