Wear resistance of Q235B carbon steel plate and 304 stainless steel plate at 400 degrees
Thread Content
Experts, at 400 degrees, which material is more wear-resistant – Q235B carbon steel plate or 304 stainless steel plate? At 400 degrees Celsius, which material is more wear-resistant? Matched to Q235B
Neither of these materials has very good wear resistance at this temperature; relatively speaking, 304 has slightly better wear resistance.
Of course, it’s 304 – it has better wear resistance
Since this is a device that operates continuously, its drums are made of carbon steel, as are the sealing plates connected to them. The operating temperature is around 400 degrees, and it doesn’t take long for the sealing plates to wear out. I now want to switch to stainless steel or other materials; are there any better options?
Stellite alloy cladding can be used, providing better wear resistance
400-degree wear resistance requires composite ND steel.
For Q235B steel plates, the allowable stress is no longer available at 400°C; in my opinion, this means it cannot be used at that temperature. Based on this, if I had to choose between the two, I would definitely go with stainless steel, but it’s also necessary to check whether the allowable stress is sufficient.
For local wear resistance, we use GBT 24186 high-strength wear-resistant steel plates for construction machinery; the temperature is lower than that of your option, by about 200 degrees, so please take that into consideration
235 The mechanical strength should be acceptable below 350°
J6630HY has excellent wear resistance and toughness
