4140 pre hardened steel plate: the steel has good workability, machining deformation of small, anti-fatigue performance is quite good.

4140 pre hardened steel plate 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.

4140 steel, the steel has good workability, machining deformation of small, anti-fatigue performance is quite good.

On the hardenability of steel, 4140 heat treatment has good strength and good comprehensive mechanical properties, good manufacturability, high yield. The highest temperature is 427 degrees Celsius. 4140 strength, high hardenability, and good toughness, quenching deformation of small, high temperature creep rupture strength, and high. 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’s price

U.S. steel prices are nearly 70% higher than the global market price, many manufacturers “orders, no steel” due to the shortage of steel raw materials in the industry, the previous 8 weeks to receive steel, but now it takes 12 to 16 weeks, the American parts manufacturers into “orders, but no steel” predicament. More than 30, 000 parts manufacturers across the country are facing similar difficulties. Steel is in short supply and US steel prices have surged 160 percent since last August.
