Professional s460nl steel welding manufacturer

Q420B material is a low-alloy high-strength structural steel. S460Nl-steel-plate-with-high-strength-carbon-structural.html target=_blank class=infotextkey>S460NL steel welding, Q420 is not high-strength steel, it is still low-carbon steel. Its tensile strength has been improved a bit. The tensile strength of Q235 steel is 235MPa, and the tensile strength of Q420B steel is 420MPa. Q420B low alloy steel has high strength and good fatigue resistance; high toughness and low brittle transition temperature; good Cold forming performance and welding performance; has good corrosion resistance and certain wear resistance.

Phosphorus element (P element) is brought into steel by ore. Generally speaking, phosphorus is also harmful element. Although phosphorus can increase the strength and hardness of S460Nl-steel-plate-with-high-strength-carbon-structural.html target=_blank class=infotextkey>S460NL steel welding etc. steel, it also causes the decrease of plasticity and impact toughness. Especially at low temperature, it makes steel significantly brittle, which is called "cold brittleness". The higher the phosphorus content is, the greater the cold brittleness is. Therefore, the phosphorus content in S460Nl-steel-plate-with-high-strength-carbon-structural.html target=_blank class=infotextkey>S460NL steel welding etc. steel is strictly controlled.

As a common steel plate in the steel market, S460Nl-steel-plate-with-high-strength-carbon-structural.html target=_blank class=infotextkey>S460NL steel welding, manganese steel plate has the following characteristics. First, good toughness, stretching and crimping can be done well. Second, the bearing strength of manganese steel plate is good and it can bear a lot of gravity. Third, the S460Nl-steel-plate-with-high-strength-carbon-structural.html target=_blank class=infotextkey>S460NL steel welding, manganese steel plate is easy to weld, easy to process finished products, and its price is relatively low. Fourth, manganese steel plate has good corrosion resistance, and long service life. Fifth, the manganese steel plate has good mechanical properties, low temperature performance, good plasticity and weldability.
