AISI 301

Manufacturer or standards-body identification; product values do not apply to every form or condition.

Specific property examples

What distinguishes this material

301 is sold in annealed and temper-rolled conditions; its work-hardening response makes the temper as important as the grade number.

Designation in this reference

Type 301

Forms covered by the sources

Cliffs sheet and strip, 0.010–0.187 in product range.

States to distinguish or confirm

Annealed; separately specified temper-rolled conditions.

Temperature and exposure

The example is the supplier’s typical annealed flat-product data at room temperature, not a guaranteed minimum for all Type 301 products.

Property evidence for a stated condition

Read the complete example before using a number. Typical values are not guaranteed limits. Missing test conditions remain visible.

Specific source example

Cleveland-Cliffs Type 301: typical annealed properties

Product / specimen: Sheet/strip in the cited supplier product programme; the typical table does not select one thickness.
Condition: Annealed
Test temperature / environment: Room temperature

Values apply to the example above
Property	Value	Meaning and method
Tensile strength	827 MPa	typical Supplier Table 1; tensile test method not specified in the table.
0.2% yield strength	310 MPa	typical 0.2% offset, supplier Table 1.
Hardness	86 HRB	typical Rockwell B, supplier Table 1.

Resolve these conditions next

What product standard, edition and complete grade are on the material certificate?
What product form, section size and delivery/heat-treatment condition will be machined?

For machining, take the exact grade, supplied condition and measured hardness where applicable into the tool maker’s application data. A generic material-family speed is not a substitute for an operation and tool-specific recommendation.

Cleveland-Cliffs 301 product data

Manufacturer flat-product datasheet; condition and dimensions are product-specific, not all bar, forging or casting supply.

Source identity, a named product example and a supplied-batch certificate are different evidence. Cross-standard similarity does not approve substitution.

Corrections from the previous article

Do not combine annealed hardness with a strength for a cold-worked temper. The cited supplier warns against assuming simultaneous tensile/yield/hardness guarantees for every temper.
Withdraw the legacy generic hardness (85 HRB) and tensile-strength (760 MPa (110 ksi)) pair: the old page does not establish a matching product, heat treatment, section and test source.
Remove the unsupported cutting-speed table and machinability percentage; select tooling only after the actual material condition is known.
