Product Material and Uses

Normally produce with ASTM 4140 alloy steel, 4130 alloy steel, 8620 alloy steel, WCB, WCC, LCC Grade and other specified alloy material.

The alloy steel casting products are widely used for Auto-cars, trains, trucks, vehicle components, and mining machinery components, agricultural machinery parts, textile machinery parts, construction machinery parts, etc.


Low and High Alloy Steels

Low Alloy Steels add alloying elements such as nickel (Ni), chromium (Cr), and molybdenum (Mo) to attain specific properties. Depending on the alloying elements used, there can be great variation between different low alloy steels.

The total alloy content can range from 2.07% to approximately 10.5%. For many low-alloy steels, the primary function of the alloying elements is to increase hardenability (the degree to which the steel will harden during heat treatment). Alloy additions can also be used to reduce environmental degradations under certain specified service conditions.

High Alloy Steels are usually a type of stainless steel, the most widely consumed commercial high alloy steel. Stainless steels contain at least 10.5% chromium, along with other alloys such as nickel to alter other properties (such as strength or weldability) in addition to corrosion resistance.
