Strength when the part has to hold
Alloy steels are low-alloy steels — iron with measured additions of chromium, molybdenum, and nickel. Those additions buy you high strength, toughness, and hardenability, so the steel can be quenched and tempered to the exact hardness your part needs. When a component has to carry load, resist fatigue, and not flinch, this is the material.
Grades we machine
4140 chromoly is the tough, versatile workhorse. 4340 nickel-chromoly steps up to very high strength for the most demanding parts. 8620 is a case-hardening grade — a hard wear surface over a tough core, ideal for gears. 4150 fills in when you need a bit more carbon. Others on request.
- 4140, 4340, 8620, 4150 and more
- Shafts, axles, gears, and load-bearing structural parts
- Heat treat coordinated to your hardness spec
- Tight tolerances with full traceability
Where alloy steel earns its keep
Drive shafts, axles, gears, fasteners, hydraulic components, oil & gas downhole tools, and load-bearing structural parts — anywhere strength and fatigue resistance matter more than weight.
Machined right, heat treated right
We machine alloy steel in the annealed condition for clean, accurate cuts, then coordinate heat treat before or after machining as your spec requires — holding tolerance through the process. It's part of our full-service manufacturing: machined, treated, finished, and delivered complete.
