| Grade / UNS | Primary ASTM Bar Standard | Alloy / Condition | Typical Purchasing Focus |
|---|---|---|---|
| 304 / S30400 | ASTM A276/A276M | Austenitic Cr-Ni stainless | General machining, fasteners and equipment parts |
| 316L / S31603 | ASTM A276/A276M | Austenitic Cr-Ni-Mo, low carbon | Corrosion-sensitive equipment, valves and process components |
| 17-4PH / S17400 | ASTM A564/A564M | Precipitation-hardening stainless | Strength-critical parts with specified heat-treatment condition |
304 and 316L are austenitic grades; 17-4PH is precipitation-hardening stainless steel. Strength, hardness and corrosion performance depend on product condition, heat treatment and service environment. Choose each grade against your actual engineering specification.
Cr-Ni austenitic grade used in general industrial and machining applications.
Low-carbon Cr-Ni-Mo grade for additional localized-corrosion resistance where specified.
Specify solution-treated or age-hardened condition, such as H900 or H1150, with the required tests.
Build your RFQ around measurable dimensions and the delivered bar condition. Stock and processing options are confirmed for the precise grade and size.
