hot rolled hardox 400 sheet hot rolled carbon steel round bar

19Mn6 steel is common carbon manganese low alloy steel produced according to DIN17155. 19Mn6 steel has strict control over harmful elements sulfur and phosphorus in chemical composition. The mass fraction of sulfur and phosphorus in the steel hot rolled HARDOX 400 sheet is not more than 0.02%. In addition, vacuum degassing technology is used in smelting, which greatly reduces the gas content in the 19Mn6 steel. 19Mn6 steel has good comprehensive mechanical properties, welding properties and technological properties.

30CrMnSiA steel delivery status: hot rolled HARDOX 400 sheet, 30CrMnSiA steel shall be delivered in the state of heat treatment (normalizing, annealing or high temperature tempering) or without heat treatment, and the delivery status shall be indicated in the contract. 30CrMnSiA steel has high strength, but it belongs to medium carbon quenched and tempered steel, with large hardenability, so its weldability is very poor. After quenching and tempering, 30CrMnSiA steel has high strength, enough toughness and good hardenability. And can be used as grinding wheel shaft, gear and sprocket.

X-rays or γ-rays are projected on the surface of the steel plate, and rubber can be placed on the other side of the steel plate. Since the radiation propagates through the steel plate and is absorbed, the intensity is different due to the presence or absence of defects, so the film can record the shape and position of the defects. This hot rolled HARDOX 400 sheet method is sensitive to the detection of common steel plate defects such as slag inclusions, porosity and pores. The disadvantage is that it is difficult to find the specific depth of the defect and it is not easy to find cracks.
