Overtime delivery at night! This is 10 pieces of heat-resistant steel 8433 die steel.
These 10 pieces of heat-resistant steel 8433 are a repeat purchase from one of our stainless steel hot forging customers. He is a high-temperature component made of hot forged austenitic, martensitic, and nickel based stainless steel. It needs to be heated to 1000-1050 ℃ using a 630 ton electric screw machine. The components weigh 0.5-2.0 kilograms and are formed in four stages, including necking, shaping, edge cutting, and final finishing.
Nowadays, when using H13 mold steel to produce 1000 products, the mold will deform, collapse, and crack. The mold life is too short, and a durable mold steel has not been found. Now that the product has started production, we need to find a mold steel with a lifespan of 10000 times.
H13 is a 4Cr5MoSiV1 chromium based hot work die steel with good toughness and a hardness of 50HRC, but its heat resistance is too poor. It is used for high-temperature parts at 1000 ℃ and cannot produce many products. The mold will be annealed off. Once annealed off, there will be no red hardness or high-temperature strength, and a series of problems such as upsetting, deformation, mold collapse, cracking, etc. will naturally occur. Your mold always needs to be lowered and repaired, and efficiency cannot be achieved.
Moreover, H13 has a decrease in overall hardness, and a new mold may be able to achieve a hardness of 1000. If the hardness is further reduced, it may only be able to achieve a hardness of 600, and further reduction would be meaningless.
When he found me last year, due to the fact that his molds are made of high-temperature parts such as hot forged stainless steel and require high heat resistance, the current H13 molds are prone to collapse and cracking. I recommended him to use heat-resistant steel 8433.
Because the heat resistance and stability of 8433 die steel are 2-3 times that of H13, with a hardness of 50-54HRC, it will not be annealed and turn red during its service life, ensuring its hardness. It is particularly worth emphasizing that even if your mold is repaired to scrap, the hardness on the back will not decrease.
Mr. Xing’s hot forged 42CrMo flange plate, when using H13 mold steel, cracked and collapsed when 3000 products were produced. However, using heat-resistant steel 8433, 10000 products could be produced each time, which is equivalent to a threefold increase in service life. And it has been downgraded 4 times without reducing its lifespan, each time exceeding 10000 times. Equivalent to one mold of 8433, used for three molds of H13.
Since using heat-resistant steel 8433 last year, this customer has been coming to purchase from time to time. This time, they have bought 10 more pieces, all with a thickness of 200 * 200 * 100mm. It is a two plate mold with an upper and lower mold structure, used for lowering and repairing molds. The customer’s willingness to make long-term repeat purchases and frequent purchases indicates that the performance of heat-resistant steel 8433 is recognized by the customer, and its lifespan is also accepted by the customer.
During this period, production has been quite busy and customers are in a hurry. We can only work overtime at night to deliver the goods to the customer. If we send them out today, he will receive them the next day and they can use them.
If your hot forging die is now made of H13 die steel, which is prone to mold collapse and cracking, has a short die life, and you don’t know which die steel to use, then you are welcome to try heat-resistant steel 8433.
When the hot forging die collapses and cracks, 8433 die steel is used, which is more delicious than eating Braised pork belly.
