What is a chrome-molybdenum tube?
Chromium molybdenum steel pipe is a kind of 4140 seamless tubing containing chromium and molybdenum. It has high strength and good impact toughness, has relatively good corrosion resistance, and low temperature impact toughness.
What's the difference between a 4130 and a 4140?
The 4130 and 4140 are similar in composition, but the 4140 has slightly more carbon and chromium than the 4130. This determines the strength and hardenability of 4140 are higher than 4130. And after quenching, the structure of 4140 is more refined than the structure of 4130, and after heating, 4140 is less easy to overheat than 4130, because the higher the carbon content of carbon steel, the more carbide formed with cr, the more refined grains.
What is 4130 mainly used for?
4130 seamless steel pipe is usually used in the condition of quenched and tempered . It can be used to make shafts, spindles and high load control wheels, high strength bolts or gears.
