introduction

Custom Alloy Steel Parts in CNC Machining

alloy steel part(1)

Alloy steel refers to steel that has a certain proportion of other metal elements or non-metallic elements added to steel to change its physical, chemical and mechanical properties. It can be divided into low alloy steel and high alloy steel.

At DEK, we have advanced CNC milling machines, CNC lathes, laser cutting machines, EDM machines, etc. and professional machining technology. We specialize in machining various types of alloy steel, such as alloy steel 4140, 4340, 1215, 4130, A514 and 8620. Whether it is simple cutting or complex precision machining, DEK always meets your diversified needs.

In addition, you can also get high-quality surface treatment (plating, painting, powder coating, etc.) as well as tight tolerances at DEK. Our precision service ensures high-quality parts for industries such as machine building, automotive and aerospace, and is ideal for gears, bearings, engine parts, turbine blades, and more.

TECHNOLOGY OVERVIEW

Basic Knowledge of Alloy Steel

What is Alloy Steel?

Alloy steel is a type of steel that contains additional elements such as manganese, silicon, nickel, copper, chromium, and others in varying proportions to enhance its properties. It is an iron-based material that can be categorized based on major alloying elements or the percentage of all alloying elements present. These alloys improve the steel's strength, hardness, corrosion resistance, and other characteristics.

It has two types– low alloy steel and high alloy steel. Low alloy steels contain small amounts of alloying elements (usually less than 5%), such as nickel, chromium, molybdenum, and manganese. On the other hand, high alloy steels contain higher amounts of alloying elements, often more than 5%. Examples of high alloy steels include stainless steels with high chromium content or tool steels with added tungsten and vanadium for improved hardness and wear resistance.

FAQ

Machining Alloy Steel Buying FAQ

Alloy steel is made by adding specific alloy elements to steel, refining by blast furnace ironmaking or electric furnace steelmaking, alloying treatment, vacuum degassing or electroslag remelting, continuous casting or die casting, and heat treatment processes such as quenching, tempering, annealing, and finally rolling, forging and machining to make steel with excellent characteristics such as high strength, wear resistance, corrosion resistance and high temperature performance.
Alloy steel is generally stronger than aluminum; it has higher tensile and yield strength.
Alloy steel is less prone to breaking than other materials due to its strength and durability.
Alloy steel is not recommended for cooking due to its composition and potential reactions with food. Stainless steel is a safer option for cookware.
Yes, alloy steel can be welded, but the specific welding process and precautions depend on the alloy's composition and intended application.
