Are you still using H900 for marine environments, or have you switched to H1150M?
ASTM A564 applies to specific physical forms: astm a564 pdf
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: Are you still using H900 for marine environments,
ASTM A564/A564M specifies requirements for hot-rolled and cold-finished age-hardening stainless steel bars and shapes, commonly used in aerospace and industrial applications. The standard covers various martensitic grades, including 17-4 PH (Type 630), detailing chemical composition, heat treatment conditions, and mechanical properties.
