Carbon Steel CNC Machining

As an alloyed steel, carbon steel is the term normally made use of for alloys of steel that are not stainless. Carbon steel can consist of light steels which are usually cost-effective and very easy to device. Higher-end carbon steels are likewise fairly easy to machine and offer high-wear resistance and tensile toughness.

Carbon Steel Subtypes

Ultimate tensile strength Yield strength Young’s modulus (modulus of elasticity) Elongation At Break Corrosion resistance Magnetism Weldability Application
Mild steel A36 400 – 520 MPa 250 – 290 MPa 190 – 200 GPa 21 – 22 % Poor Semi-magnetic Excellent Structural application,Automotive industry,Heavy equipment,Oil & Gas industry Learn More
Mild steel 1018 380 – 450 MPa 220 – 350 MPa 190 – 205 GPa 13 – 25 % Poor Semi-magnetic Excellent Gears & Pins,Rams & Shafts,Rolls & Sockets,Axles Learn More
Carbon Steel 1045 600 – 630 MPa 310 – 320 MPa 190 – 205 GPa 16 % Poor Semi-magnetic High Axles,Bolts,Forged connection rods,Crankshafts,Torsion bars Learn More

Cost-saving Design Tips

Steel is one of the cheapest materials suitable for CNC machining. However, take care to avoid unnecessary machining costs. Below are some cost-saving design tips:

1.Material selection

Cheap though it may appear, it is essential to pick the best steel for your application. Utilizing high-strength alloy steel where mild steel will certainly work boosts expenses for no included advantage.

2.Part setup

Designing a part to decrease the number of machining setups can considerably decrease the cost of manufacturing. This is specifically true when machining low-cost products as any kind of expense savings on the material can be quickly removed by pricey setups.

FAQs

There are 2 grades of steel that are best for machining. The type of parts you need will dictate which grade you choose:

1018 Steel is a mild, low carbon steel that is machinable, weldable and is useful where there are no requirements for high strength.
1045 Carbon Steel is stronger than low carbon steel but is easy to machine.

Steel is the workhorse of the industry because of its economical cost, wide availability, ease of processing and good mechanical properties. Most steels have good machinability and weldability and take well to heat treatments. Some are stronger and harder than others but most steels offer a combination of toughness and wear resistance.

Steel is a good choice in terms of strength and durability, but its weight is the biggest drawback in comparison to other materials. There are more than 3500 grades of steel to work with and different grades behave differently when being machined. Some types of steel are specifically designed for greater ease when machining. Some steels have high work hardening tendencies and this necessitates the need to keep the machining process moving so there is no unnecessary heat build up. With CNC machining steel it is also important to keep tools sharp.
