What is CNC Machining Steel?
Iron-carbon alloys are divided into two categories: steel and iron. Steel is an iron-carbon alloy with a carbon content of 0.03% to 2%. According to the different carbon content, carbon steel is divided into low carbon steel, medium carbon steel and high carbon steel and alloy steel. The cnc machining process is very different. Steel offers a great balance between cost and functionality since it is easy to machine and weld. But it easily rusts,so there are many methods for the surface plating.
As a professional CNC machined shop,Worthy Hardware is more familiar with CNC machining steel parts.We are more well know how to make the parts without burrs, how to improve the surface roughness, and how to drill more deep depth holes.
What are the benefits of CNC Machining Steel?
Compared with CNC machining stainless steel, steel is much harder and stronger than stainless steel. And it is more practicability and economy.
1) Durable : Steel is very strong and shock resistant. So it is a popular material for buildings, plumbing and supporting modern roads.
2) Safety : Compared with many other materials, steel can be handled and used safely. It is also a good material that can withstand fires, hurricanes, tornadoes and earthquakes.
3) Steel is easy to recycle, making it environmentally friendly.
4) Economical : For many uses, such as pipes, steel can be made very thin compared to other metals. This makes it very cost-effective. For example, carbon steel pipes are cheaper than brass pipes.
5) Healthy and durable cookware : Aluminum cookware can react with food and may cause health problems. Carbon steel cookware also has a longer life than aluminum.
Due to its strength, economy and safety, these are some of the main reasons why CNC machining steel is the best choice for so many applications.
CNC Machining Steel Material
There are many types of steel, carbon steel is one of the types. The amount of carbon varies though, causing the properties to vary considerably.There are low, medium, or high carbon steels. Meanwhile if adding one or more alloying elements to carbon steel, such as chromium,it becomes alloy steels.
Steel 1010
Steel 1010 is a high-quality carbon steel with low mechanical strength, good plasticity and toughness. It is easy to be molded under cold conditions, easy to cut and process, and has good welding performance. To improve the surface hardness, it can be carburized and cyanided.

Justin, CEO of a lighting company
I inspected the top two pieces of all five boxes. Everything is beautiful! BEAUTIFUL! You remove so much stress from my shoulders. I know that when we pay you to manufacture a product, it will be made perfectly. The glass bead blasting and anodizing is always beautiful. I am so very happy! You make it easier for us to run our business. There is no trouble! With most factories, I have a moment of fear before I open their boxes. Will the components be made correctly? Do they care about quality? It is often a war. And Dennis has to fight the war, treating most factories like small children! But, not your company. You’re company is world-class. You make beautiful components!Thank you very much for your hard work. We will work together for many lifetimes!
David, General manager for a family owned business
I’ve been working with Chinese manufacturers since 2004 and had some really unfortunate partnerships until 2012 when we partnered with Worthy Hardware. At first,we only gave them small orders to test and make the start. However,their response speed was very fast ,and their engineers help us improved our designs more simple, this helped us reduce a lot of cost.Our cooperate is more and more stable! We trust Worthy Hardware always ,very responsible. Your guys are great! .Worthy Hardware is by far my favorite, because of the way they handle business and the quality of what they make.If you are from USA and would like to know more about Worthy Hardware,i would be very happy to be as an endorsement.
