Match the Grade to Your Final Requirement
A grade comparison is useful only when the product and final condition are explicit.
| Selection question | What to confirm |
|---|---|
| 1117 or 1144 turned part | Chemistry, product route, stock condition and final fit |
| 52100 bearing feature | Incoming state, treatment, finishing and bearing geometry |
| 9310 carburized component | Case/core definitions, tooth route and final evidence |
Material names are not interchangeable process plans.
Keep the ordered standard, section and supplied state explicit.
Other grade required?
For 1040 carbon steel or another callout, send the exact specification and required condition for review before availability and process scope are confirmed.

Answers Before You Specify
How do I choose steel for custom machined parts?
Start with load, final fits, exposure, required condition and records. Then compare the complete grade and product specification against your manufacturing route.
Can 1144 steel be welded?
Do not assume weldability from a free-machining grade name. Review exact chemistry, stock condition, joint and procedure before selecting a welded route.
Can 52100 steel be machined after hardening?
Review hardness, geometry, access and surface requirements before choosing hard machining or grinding. Confirm the actual route and acceptance for your part.
How should I specify case depth for 9310 gears?
State effective or total case depth, test method, locations, core requirement and permitted finishing removal. Keep the tooth and final-fit requirements on the same drawing.
Does 52100 steel rust?
It is bearing steel, not stainless steel. Define exposure, handling, protection and storage for your finished part.
How much does 9310 steel machining cost?
Send the controlled drawing, stock condition, quantity, case/core requirements, tooth-processing scope, finish and inspection needs.
Can you review a grade not listed here?
Send the exact material standard, product form and condition, including an 1040 steel callout if required. Availability and manufacturing scope are confirmed for your drawing.
