Yesterday I wasted my time twice, but by the third time, I wasn’t going to play along anymore—because Teacher Li Huan once said, “Don’t do business with people who drag things out.”  Yesterday, a netizen was clearly not meant to be my customer.  The first time, he placed an order for a piece of 8566…

Six years later, Mr. Wei, who had purchased 8566 die steel in 2020, returned to buy more 8566 die steel.  His first words were, “8566 die steel is a bit pricey, but the products produced through hot forging are truly beautiful—the surface finish is excellent. Of all the die steels I’ve used, none compare to it in…

Last night, an online friend I hadn’t been in touch with for years suddenly reached out to me and asked what the tungsten (W) content of W6 is.  [Explanation: W6 refers to a general-purpose high-speed steel with the alloy composition W6Mo5Cr4V2, abbreviated as 6-5-4-2. It is commonly referred to as W6 (pronounced “tungsten 6”) in everyday…

There’s a street in Dongguan called Shijing Avenue. Along this stretch—less than 1 kilometer long—there are seven or eight roast goose restaurants, but only one is bustling with customers, where diners have to wait in line. The others are either struggling or frequently changing owners.  This illustrates that to run a successful business, you must…

DC53 is a die steel that has been overused to the point of exhaustion.  Mr. Wang from Cangzhou is stamping 3.75-thick hot-rolled Q235 steel sheets. The mold manufacturer said they used DC53, but the cutting edges need to be sharpened after only 20,000 strokes; otherwise, the products will have significant burrs.  When stamping 3.75-thick Q235…

Some narrow edge punches may crack, but you really use 8566 anti collapse steel. I just received a consultation from a netizen. He punched a 1.25-thick 62 copper with a punch width of only 0.7mm. The punch wall thickness is smaller than the plate thickness, and the punching ratio is less than 1:1. Now, he…

Mr. Chen told me that Q195 iron casters with a tensile strength of 1.1mm have a relatively high tensile height, and Cr12MoV cannot be produced without coating. It is impossible to produce 100 products before starting the wire drawing process. However, using non stick 8503 and stretching 30000 products, there will be a little bit…

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…

A major client from Guangdong placed an order for 75 pieces of high-toughness LG mold steel with me, and I’m very pleased.  Seeing the 75 pieces of high-toughness LG mold steel ready for shipment in the workshop—40 pieces of LG premium material for mold cores and 35 pieces of round bar for insert cores—really put me in a…

Early this morning, Boss Zhang—whom I hadn’t been in touch with for five years—sent me a message. He’s working with stainless steel, which is prone to chipping at the corners, and asked me to send over a sample to test.  After asking a few questions, I learned that he’s punching 2mm-thick stainless steel with products…

Mr. Zhang said, “The 8566 die steel we used last time was great. Things are going much more smoothly now. Thank you, General Manager Wu.”  Receiving praise from a long-time customer really lifts my spirits.  Mr. Zhang’s mold is used for the cold trimming process after hot forging. The original DC53 punch was prone to chipping…

I have to admit, the current “Four Copies 8566” has done a very thorough job of copying—it’s a good student.  I saw that you wrote right at the beginning that 8566’s resistance to chipping is four times that of SKH-9 high-speed steel and twice that of D2, with a hardness of HRC 58–61. It’s primarily…
