4140 plate is high strength, hardenability, good toughness, small deformation during quenching
4140 plate
4140 plate
this steel has good workability, slight processing deformation, fatigue resistance is quite good, is a medium and so on hardenable steel, 4140 heat treatment has better strength and good comprehensive mechanical properties, good processability, yield High. The highest use temperature is 427 degrees Celsius. 4140 strength, high hardenability, good toughness, small deformation during quenching, high creep strength and long-term strength at high temperature. It is used to manufacture forgings that require higher strength and larger quenched and tempered section than 35CrMo steel, such as large gears for locomotive traction, supercharger transmission gears, rear axles, heavily loaded connecting rods and spring clips. Petroleum deep well drill pipe joints and fishing tools below 2000m, and can be used in the mold of the bending machine.

Otai is the largest stockist in the south of China.there are a wide rage specification in stock always.
We had 20 year experience of 4140 plate trade and processing ,and had trade with middle east& sounth American countries.etc.we also offer milling and graiding processing,and most of the customer will take it for automobile die.we offer three condition.NO.1,hot rolled,black surface.NO.2.Q+T,No.3,Annealed.and the Q+T hardness would be 28-32 HRC generlly.
Thickness would be 12-350mm are avaliable,and wide would be 2000-2300mm,Length would be 3000-5800mm,we also offer cutting if you need.we have our own cutting merchine,then the delivery day would be sooner than your expection.
Please let us know which condition and which specification would be perfect for you,we also will offer tenical support when you need.
