Benefits of Steel CNC Machining

Here’s why steel CNC machining stands out:

Super Accurate: We can make parts with exact measurements (as close as ±0.005mm)
Very Strong: Steel parts can handle heavy loads and tough conditions
Cost-Effective: Our methods waste less material and work well for big orders
Great Finish: We can make parts smooth or textured, just as you need
Long-Lasting: Steel parts resist wear and tear for years of use

Types of Steel We Work With

We work with many types of steel to match what you need:

Steel Type	Key Features	Common Uses
Mild Steel (A36)	Low cost, good strength	Brackets, frames, machinery parts
Stainless Steel (304/316L)	Doesn’t rust, clean look	Food equipment, marine parts, outdoor items
Alloy Steel	Extra strong with added metals	Gears, shafts, high-stress parts
Tool Steel	Stays strong when hot, resists wear	Molds, dies, cutting tools

Our team at Istar Machining helps pick the right steel for your job. We match the steel to how the part will be used, what it needs to do, and your budget.

Frequently Asked Question

What Is Steel CNC Machining?

Steel CNC machining uses computer-controlled tools to shape steel into exact parts. Our machines follow digital plans to cut, drill, and shape steel with perfect accuracy. At Istar Machining, we use top-quality machines to make parts that meet your exact needs.

How long does steel CNC machining take?

Simple parts can be done in 5-7 days. Complex parts or large orders take 2-4 weeks.

What's the smallest detail you can machine in steel?

We can make features as small as 0.5mm in most steels.

Can you machine hardened steel?

Yes, we use special tools and techniques for hardened steel, though it may take longer.

What's the difference between milling and turning for steel parts?

CNC milling uses rotating tools to cut material, while CNC turning spins the material against fixed tools.

How do I know which steel to choose?

We help pick the right steel based on strength needs, environment, budget, and how the part will be used.
