Alloy steel material introduction


Alloy steel is high polymer material that be alloyed with a variety of elements in total amounts between 1.0% and 50% by weight to improve its mechanical properties.


The term "alloy steel" is the standard term referring to steels with other alloying elements in addition to the carbon. Common alloyants include manganese (the most common one), nickel, chromium, molybdenum, vanadium, silicon, and boron. Less common alloyants include aluminum, cobalt, copper, cerium, niobium, titanium, tungsten, tin, zinc, lead, and zirconium.


The following is a range of improved properties in alloy steels (as compared to carbon steels): strength, hardness, toughness, wear resistance, hardenability, and hot hardness.


The chassis before install the protection plate:


Perfect match installation:



And our invented alloy steel engine protection plate is combines the advantages and avoid the disadvantages of the common steel material.  

  1. Safety. Never stop the engine sinks while crash to protect the driver and passenger.
  2. Tough. Using new material of alloy plastic steel.
  3. Light. 5 mm thickness and max 2.5-3kg,save fuel.
  4. No resonances noice.
  5. All holes sealed.sand-proof and dust-proof.
  6. Sepical design air inlet and air outlet hole for engine cooling.
  7. Special design for different car models, more than 200 models,reserve oil leaking hole and gearbox hole.

 Our plate will follow the engine falls down when crash happens to protect the driver:
