42crmo4 precision steel flat bar: We keep a daily inventory of 1500 tons

42crmo4 precision steel flat bar China suppliers, wholesale, distributors, and stockholder–Dongguan Otai Special Steel Co Ltd. We Otai is a manufacturer and has a large quantity of stock in our warehouse. We supply in Round bar, gauge plate steel, pipe, tube, rod, square, hexagonal, blanks, plate, sheet, precision ground flat bar. Including precision ground bar stock, hollow bar, we provide black surface and black surface alloy steel material.

1)  42crmo4 steel belongs to the alloy structural steel. After Quenching & Tempering, its hardness is 28-34 HRC.

2) 42crmo4 steel used for bending machine molds.

3) Besides, it can be used to under 2000m deep well of oil drill pipe joint and the fishing tool.

4) Also, it can be used for engineering structural parts, like high tensile shafts, gears, pinions, and spindles.

42crmo4 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, 42crmo4 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, 42crmo4 steel is not stainless steel. Please pay attention to its rust prevention when using it.

But 42crmo4 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.

Otai provides the grinding, milling, polishing, turning, drilling, and other machining services as your required tolerances and size. (42crmo4 precision steel flat bar: We keep a daily inventory of 1500 tons)

Today we will offer the latest steel news for you.

B： 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.  China will allow more thermal coal imports and higher domestic production of the raw material to raise electricity generation rates. Moreover, the supply of coal could be guaranteed by using reserve sources and stocks in the coming winter.

A： 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.

B： 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.

A： In these few months, 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.

By the way, for 4140 steel, we can supply the 4140 precision steel sheet, round bar, and flat bar.

B： Rectangular pieces can be cut from flat bar or plate to your specific sizes.
