A netizen just asked me, what kind of tool steel should be used for large-sized hexagonal nuts made of hot forged 35CrMo material?
In early March, there was just such a successful case. Many mold cases, after turning around, have come back to me.
Mr. Bao is a hot forged 35CrMo hex nut that was punched with a bottom mold. Originally, H13 was used, which had a short lifespan. The customer was unhappy and requested that he find a way to increase the lifespan of the mold, reduce the frequency of mold repairs, and improve production efficiency.
But Mr. Bao’s mold, after using heat-resistant steel 8433, told me that the lifespan of 8433 was twice that of H13. H13 had 20000 pieces and 8433 had 40000 pieces. After 40000 pieces were made, there were no marks on the mold. I asked the customer to continue making until it was scrapped, and a total of 58000 pieces were made. The customer is very satisfied with the mold made by 8433 and has placed another order with me.
According to Mr. Bao’s reply, the hot forged 35CrMo hex nut was made of heat-resistant steel 8433 for the bottom mold, and the mold life was increased from 20000 pieces to 58000 pieces, which is equivalent to a threefold increase. A threefold increase in lifespan means that the goal of reducing mold repairs by 2 times, minimizing downtime by 2 times, reducing mold repair frequency, and improving production efficiency has been achieved.
So, today’s netizen asked me, what tool steel should be used for large-sized hexagonal nuts made of hot forged 35CrMo material? I still recommend the heat-resistant steel 8433. When H13 is used for hot forging die, it will collapse and crack. The 8433 die steel is more delicious than eating Braised pork belly.
