3m X 6m X 150mm JIS SG325 mild steel plate PlatePageviews:
S460Q steel plate is a quenched and tempered high-strength steel plate, the series grades are S460Q, S460QL, S460QL1, and the European standard EN10025-6 is implemented. S460QL1 steel plate is mainly used to manufacture low-temperature resistant, high-strength key components, construction machinery, mining machinery structures, etc. It is a high-strength structural steel plate. S460QL1 steel plate delivery status: quenched and tempered (quenched + tempered).
The performance of heat treatment process reflects the difficulty of heat treatment and the tendency of defects of the steel. It mainly includes hardenability, superheat sensitivity, temper embrittlement tendency and oxidation decarburization tendency. The hardenability of JIS SG325 mild steel plate, alloy steel is high. The cooling method can be used slowly during quenching, which can reduce the deformation and cracking tendency of the workpiece. The addition of Mn and Si will increase the superheat sensitivity of steel. The strengthening effect of alloy elements on steel in quenching and tempering state is the most significant.
For stainless steel plate cutting, the choice of cutting method is determined by the thickness of steel plate. If the thickness of JIS SG325 mild steel plate stainless steel plate is more than 20 mm, flame cutting is adopted, while the thin plate is suitable for plasma cutting. In addition, if the cutting requirements are relatively high, laser cutting can be used. In addition, if the JIS SG325 mild steel plate stainless steel plate is used as a billboard, plasma cutting is adopted, Because it uses thin plates.
