Standard Specification for Hot-Rolled and Cold-Finished Age-Hardening Stainless Steel Bars and Shapes.
Stop overpaying for 17-4 PH stainless steel. Read the spec first. 🛑
The PDF outlines strict requirements for mechanical properties based on the grade and condition: astm a564 pdf
ASTM A564 covers a variety of shapes including rounds, squares, hexagons, angles, tees, and channels. These can be produced via hot rolling, extruding, or forging. The specification is critical for applications requiring high mechanical performance at room temperature or elevated temperatures up to . Common Grades and Designations
I’ve seen too many buyers just ask for "Condition H900" without verifying the mechanical limits. Here is why the is your best friend for the next RFQ: 🛑 The PDF outlines strict requirements for mechanical
This specification covers age-hardening stainless steels that are used primarily for parts requiring high strength, good corrosion resistance, and good mechanical properties at both ambient and elevated temperatures.
The most widely used grade under this specification is , commonly known as 17-4 PH . Other specialized grades provide varying balances of toughness, strength, and corrosion resistance. Common Grades and Designations I’ve seen too many
"17-4" is a nickname. The law is ASTM A564/A564M (Standard Specification for Hot-Rolled and Cold-Finished Age-Hardening Stainless Steel Bars).
Are you still using H900 for marine environments, or have you switched to H1150M?
You order "17-4 Stainless." The mill sends "Condition A" (annealed). You try to machine it, and it’s gummy. 🥴 Because you forgot to specify the heat treat condition.
