Alloy Steel
Alloy steel which is alloyed to improve its physical characteristics with such a range of variables about 1 per cent to 50 per cent by mass. Alloy steels are split into two types:-Low alloy steel and high alloy steel. The alloying components main function is to focus on improving strength to enhance mechanical characterists and hardness after high temperature. Low alloy steel contains a massive alloy quality of 1.5 to 5 per cent.
Equivalent grades:
Alloy Steel is by far the most efficient metal discovering widespread use as part of construction applications and also a variety of our regular life. It is also important to get finest Alloy Steel.

EN19
EN19 is high-quality alloy steel with tensile strength. With a combination of shock resistance
and good ductility, EN19 is suitable for application with very high loading such as engine gearboxes. Popular in the automotive sector it is possible to machine the material extremely accurately, in recent years EN19 has become an established material in the Oil & Gas sector. The material lends itself well to any application where strength is a primary consideration.
Alloyed and pre-toughened steel with high resistance and high toughness; universally usable in engineering when toughened and pre-hardened machine construction, base plates, axes, gear shafts, gear wheels.
