SUPERIOR IN STEEL PRODUCTION AND MACHINING OPERATIONS
Alloy Steel Grades
Alloy steel grades are versatile grades that possess overall combinations of toughness, strength, fatigue strength, and wear resistance.
Alloy steels are made out of a lot of elements and metals that are alloyed together to create tough properties that are required in a very vast variety of applications in various industries. Alloy steel grades mostly have reasonable strength up to high temperatures at around 600o and even above as well as excellent atmospheric corrosion resistance. These alloy grades are almost ideal for multiple forgings to form very accurate sizes that are intended for a specific application. It is best advisable to forge certain alloy steel grades that are not below 1600°.
Alloy steel grades mainly fit for various applications like aerospace, agricultural and defense industries, myriad uses in automotive, gas industries, typical uses in shafts, spindles, and forged gears.
In addition, with its featured properties, alloy steel grades can undergo a lot of machining operations and conditions:
- Heat Treatment
Their machinability is highly permitted with its optimum structure. Since alloy steel grades possess good weldability, they can be forged easily through any commercial methods.
