4140 alloy plate
A：Let me share with you something interesting. My customer—— Mike asked me what is the difference between P20 steel and 4140 steel.
B：From the analysis of the composition, they don’t seem to be much different.
A：Yes. But in fact, P20 steel belongs to plastic mold steel, while 4140 steel is alloy structural steel.
B：I have checked the information and found that the carbon content of P20 steel is 0.3%, while 4140 steel is 0.42%.
A：Usually the hardness of P20 steel in the delivery state is 28-34HRC.
B：The delivery status of 4140 steel is usually annealed or tempered according to our customer’s requirements.
A：Then let’s talk about the use of these two materials.
B：P20 steel can be used for the plastic mold.
A：4140 steel can be used for engineering structural parts, like high tensile shafts and gears. (4140 alloy plate)
B：Another is that 4140 steel is an alloy structural steel with higher alloying elements than P20 steel, so the price of 4140 steel will be higher than P20 steel.
A：I hope that customers should consider what kind of performance you need for the steel you purchase and then buy on demand.
B：The above is about the difference between P20 steel and 4140 steel. If you want to know more, you can visit our website：www.otaisteel.com
