Steel Machining

Steel is an alloy of iron and carbon and other elements. Because of its high tensile strength and low cost, it is a major component used in buildings, infrastructure, tools, ships, automobiles, machines, appliances, and weapons. If you are thinking of getting different steel parts CNC machined, then we have you covered. We provide CNC machining services for steel and its different grades including mild steel , carbon steel, plain carbon steel, low & high alloy steel etc. We have a vast variety of equipment and tools for CNC machining of steel. These equipment help us deliver the best end product to our customers.

CNC Machining Service

Our CNC machining, turning, and milling processes include all types of turning, boring, broaching, and more. With our 3, 4 and 5-axis machinery, we can custom manufacture parts of the highest quality to meet your demands. Using the most technologically advanced capabilities, we can work with tolerances up to ± .0001 inches.

Some of the Many Materials We Work With:

Machining Materials Guide
Type General Characteristics Alloy Common Applications Tolerances for a 1/2" Dia. Bar Material Cost Factor Machining Cost Factor
Steel Moderate strength and low-stress applications. 1008 Good matte surface finish that makes it suitable for exposed parts + 1.2 3.5
Plain low carbon steel, poor machinability but good formability and weldability. Case harden only 1018 Rivets and parts requiring strong welds Cold drawn 0.9 2.4
Strength, impact resistance and higher tensile strength. 1045 Responds to heat treatment extremely well, but it not recommended for case hardening + 0.9 3
Higher carbon, higher strength, direct hardening 1137 Higher stress applications, gears, shafts, studs, etc. Cold drawn 1.6 2.7
Strength and machinability 11L37 Easily machined and can be annealed, quenched, tempered, and heat treated + 5.1 2.2
Strength and hardness and a more uniform surface hardness 11L41 Axles, shafts, bolts, and pins + 2.5 2.3
Designed for excellent machinability. Case hard only 12L14 Endless commercial products; probably more pounds used in turned products than any other bar stock Cold drawn 1 1
Designed for good machinability. Case harden only 1215 Parts needing better formability or weldability than 12L14 Cold drawn 1 1.2
Strength, toughness, and fatigue resistance 4130 Military and commercial aircraft parts Norm AQ 1.5 2.7
HT Condition F4 2 --
Popular general-purpose alloy. Direct hardening 4140/4142 Gears, shafts, pins, bolts and nuts, pump and valve components Cold drawn 1.1 2.9
Designed for better machining w/lead additive; direct hardening 41L40 Couplings, shafts, tooling, bolts Cold drawn 2.5 2.8
