4140 flat bar VS 4140 plate.what’s the different between them?
Actually,the chemical property and mechanical property are same,
4140 plate size should be thickness*2250mm*3000~5800mm
4140 flat bar size should be thickness*300~1100mm*2250mm

Recently, some localities in China have imposed power restrictions, triggering concerns about energy supply for winter.
A spokesman for China’s National Development and Reform Commission (NDRC) said at a press conference on September 29, that China will allow more thermal coal imports and higher domestic production of the raw material( aisi 4140 round bar)to raise electricity generation rates.
Wuhan Iron and Steel Co., Ltd., subsidiary of major Chinese steelmaker Baowu Group, has announced that it plans to carry out maintenance work.
During the October 21-November 9 periods on its 1,580 mm hot-rolled production lines, which will result in a shortfall of 150,000 mt in its HRC output.
On September 27, inventory of iron ore at 33 major Chinese ports amounted to 120.01 million mt, down 0.78 percent compared to September 13, as announced by China’s Xinhua News Agency.
The rising deliveries in the global market will exert additional pressure. The production restrictions in Hebei and Jiangsu provinces will continue to negatively affect the demand for iron ore, weakening the support for ore prices.
In these few month, the Covid-19 pandemic in the overseas market negatively affected the demand for longs, while most Chinese producers were focused on domestic sales.
In the January-August period of the current year, China’s exports of rebar totaled 6.31 million mt, up 29.6 percent year on year, while wire rod export amounted to 1.42 million mt, up 10.5 percent year on year.

4130 VS 4340,They both contain,chromium.
What is the different between 4130 VS 4340? Let’s see our team members how to distinguish it.
AiSi 4140 plate mechanical properties, For normal condition ,it would be nomalized & Q+T.
But if you have a special demand of AiSi 4140 plate mechanical properties.we could do the customized.
4140 ph plate，first of all,we need to understand this material.
Generally, the common antirust elements are Cr and nickel. The Cr content of 4140 ph plate is only 0.9-12.0; The requirement of Ni is less than 0.3. the antirust Cr should be 12.5% at least, and the basic antirust ability can only be obtained when Ni is more than %5.00.
4140 ph plate is a high-strength low-alloy steel with high strength and toughness, good hardenability, tempering brittleness is unobvious, high fatigue limit and multiple impact resistance after quenching and tempering treatment, and good low-temperature impact toughness. The steel is suitable for manufacturing large and medium-sized plastic molds requiring certain strength and toughness.
This kind of steel has no anti-corrosion performance.so,it might rust. It can’t be said that it is easy to rust. It mainly depends on preservation.
To prevent rust, it is necessary to carry out surface anti-corrosion treatment. If the surface is oiled, it is not easy to rust. The most common surface consition is black surface.
4140 pht plate with strick tolerance,
4140 pht plate in good strength and good comprehensive mechanical properties.
Our 4140 pht plate offer both black surface and milling surface,
Also we could offer 4140 pht plate in a strick tolerance.
Let’s see out 4140 pht plate milling processing.
