A process supervision system has been set up to let each customer supervise the process of the system with us

After quenching and tempering, the 40Cr alloy steel plate has good comprehensive mechanical properties, good low-temperature impact toughness and low notch sensitivity. The hardenability of steel is good. It can be hardened to Ф28~60mm in water quenching and Ф15~40mm in oil quenching. In addition to quenching and tempering, 40cr sheet is also suitable for cyanidation and high-frequency quenching.

Heat treatment process: heat treatment refers to a kind of process operation in which the metal or alloy can change the internal structure through certain heating, heat preservation and cooling methods in the solid range to obtain the required performance. S355M VS S355N Heat treatment process refers to the ability to change the microstructure and properties of S355M VS S355N after heat treatment, including hardenability, hardenability, temper brittleness, etc.

S355M VS S355N, Low alloy steel plate is a general designation, mainly refers to the steel plate with alloy content less than 3.5%. Alloy steel in the market is distinguished by the total amount of alloy elements, mainly including low alloy steel, medium alloy steel and high alloy steel. When the total alloy amount is less than 3.5%, it is called low alloy steel; if the total alloy amount is 5-10%, it is medium alloy steel; and when the total alloy amount is more than 10%, it is high alloy steel.
