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.● Small to Large Quantities
Machining Materials Guide
Tolerances for a 1/2" Dia. Bar
Material Cost Factor
Machining Cost Factor
Moderate strength and low-stress applications.
Good matte surface finish that makes it suitable for exposed parts
Plain low carbon steel, poor machinability but good formability and weldability. Case harden only
Rivets and parts requiring strong welds
Strength, impact resistance and higher tensile strength.
Responds to heat treatment extremely well, but it not recommended for case hardening
Higher carbon, higher strength, direct hardening
Higher stress applications, gears, shafts, studs, etc.
Strength and machinability
Easily machined and can be annealed, quenched, tempered, and heat treated
Strength and hardness and a more uniform surface hardness
Axles, shafts, bolts, and pins
Designed for excellent machinability. Case hard only
Endless commercial products; probably more pounds used in turned products than any other bar stock
Designed for good machinability. Case harden only
Parts needing better formability or weldability than 12L14
Strength, toughness, and fatigue resistance
Military and commercial aircraft parts
HT Condition F4
Popular general-purpose alloy. Direct hardening
Gears, shafts, pins, bolts and nuts, pump and valve components
Designed for better machining w/lead additive; direct hardening
Couplings, shafts, tooling, bolts
.55% Ni, .50% Cr, .20% Mo, heat treatable and case hardening
Shafts, bushings, pins, gears, bolts
Very high 1% carbon, .25% Ni,1.4% Cr, .08% Mo
