5140 Steel rod, 5140 steel rod Hot Rolled Alloy Steel Round Bar
5140 steel has good comprehensive mechanical properties and is one of the most widely used steel types, used for manufacturing parts of medium speed and medium load, such as machine tool gear, shaft, worm, spline shaft and so on.
AISI 5140 steel also can be called JIS Scr440 and DIN 1.7035 steel. It is one of the alloy steel. And it is one of the most popular steel grades in the productions of the machine. The 5140 steel round bar is on the medium level and it was easy to processing. After tempering and quenching, the toughness, plasticity and wearing resistance of it will get better. Steel normalizing can make the spheroidizing for the organization of steel get easier. And it will raise the machinability of the semi-finished product with the hardness less than 160HBS. Tempering it at the temperature of 550℃-570℃ which can make it get better mechanical property. And the hardenability of it is higher than S45C steel. You can check 5140 Steel chemical composition and heat treatment as below.
