Our steel materials meet DIN / ASTM / EN / JIS etc different international standards. Otai stocks 4140 alloy steel flat bars and keeps daily inventory of 1000 tons which is hard for competitors.  

4140 alloy 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.
