Why 8620 steel flat bar is preferred for machine parts?

Today, there is an 8620 steel flat bar inquiry from Switzerland. During the communication with the customer, I talked about some characteristics of 8620 steel. I was often asked if the 8620 steel is a material. I will explain it to you today.

ASTM A29/A29M-04 ASTM8620 is an alloy, widely used for carburizing and carbonitride of Cr-Ni-Mo series surface hardened steel.

8620 steel flat bar is commonly used in the manufacture of small and medium-sized cars, tractors engines, and gear in the transmission system. It can also replace 12CrNi3 steel to manufacture carburized and cyanated parts with higher core performance, such as teeth and roller body of roller bit for oil drilling and metallurgical open-pit mines. Molybdenum 8620 contains not only good comprehensive performance but also can withstand certain temperatures, so it can be used for manufacturing connecting rod valve cross-section forgings of turbine gear whole rotor internal combustion engine.

 

Why 8620 steel is preferred for these machine parts

 

When the 8620 alloys are properly carburized — heated to a set temperature and then exposed to an agent containing carbon, a process which adds an extra layer of carbon to the outside of the steel, thereby making it stronger — it is used to make such machine parts as gears, crankshafts, and gear rings. Carburized 8620 alloy is strong and durable, which is why it is preferred for these parts.

 

AISI 8620 is an alloy carburizing steel when thermally treated develops a hard outer case with a soft ductile core. Carefully controlled proportions of chromium, nickel, and molybdenum are responsible for the extensive use as carburizing alloy steel, with valuable features including extreme surface hardenability and good internal strength. Has minimum distortion and growth characteristics. 8620 steel flat bar has good machinability and responds well to polishing.

 

Otai exports various tool steel and alloy to more than 30 countries from Europe and America, Middle East, and Asia. Our steel materials meet DIN / ASTM / EN / JIS etc different international standards.

I told Mr. Chen: MTC, our family sure can provide it. but I believe once you search it online, every one can offer it.but to determine whether this company has real stock, genuine goods, it is best to come to our factory to check.

I can give you a spectrometer to see the ingredients. If you think that’s so far,and quite hard for you to come, we will use WeChat video calling. We have stocks of 42CrMo4 plates in hundreds tons, and we supply raw materials to the local mask machine.

The quality is definitely high quality,as it’s for mask machine, and we will not ruin our reputation because of an order. Later, Mr. Chen really drove hundreds kilometers to our factory to see the goods.

I saw that our warehouse really had such much goods in stock, and also saw our testing equipment: direct reading spectrometer, hardness tester, ultrasonic Testers, etc., also saw that many people came and did purchased, he signed a contract immediately, saying that they finally found a reliable supplier, whether it is 42CrMo4 or alloy steel or mold steel will purchase with us.
