4140 hr plate: Its heat treatment has good strength and good comprehensive mechanical properties.
The common stainless steel’s chromium content is higher than 12.5%. So it has anti-rust performance. From the analysis of the composition, 4140 steel also has chromium. But its chromium content is only 0.8%-1.1%, which is far lower than the standard for rust prevention. Therefore, 4140 steel is not stainless steel. Please pay attention to its rust prevention when using it.
But 4140 steel can be used to make gears. Because lubricating oil is often used when gears are running. The lubricating oil can protect the gear from rust while protecting the normal operation of the gear.
It is used for manufacturing forgings with higher strength and larger tempering cross-section than 35CrMo steel, such as big gear for locomotive traction, supercharger drive gear, rear axle, connecting rod, and spring clamp with great load also can be used for drilling pipe joint and fishing tool of oil deep well below 2000m and can be used for bending machine mold, etc.
News about the steel
The price of bulk commodities (4140 hr plate )only climbs to the middle and takes a break, and will continue to rise. Because the factors that led to the rise of bulk commodity prices have not changed, the released water is still there, the dollar is still weak, and the supply gap is still there. The recovery of the global economy is still expected, and inflation expectations, in turn, are still pushing up, and commodity prices will continue to rise.
