17-4 PH is a precipitation-hardening martensitic stainless steel that contains copper. In its solution-treated and double-aged condition, it has become the preferred alloy for stems and shafts, and is widely used in valve internals. It offers high strength, with good properties up to 315°C (600°F), and excellent corrosion resistance, comparable to 304 austenitic stainless steel in many environments, making it a highly versatile alloy.
NACE MR0175 imposes limitations on hardness and restricts the alloy's age-hardening treatments to two specific cycles. It only permits solution treatment followed by double aging to either the H1150M condition (760°C / 1400°F followed by 620°C / 1150°F) or the DH1150 condition (620°C / 1150°F for both stages).

This is a martensitic stainless steel used in the hardened and tempered condition, typically available in tubular form, either as mechanical tube or casing tube. It is manufactured according to ASTM A519 standards for mechanical tube supply.
When bill of material requirements align with available stock sizes, significant cost savings can be achieved in both raw material supply and manufacturing, compared to bar product form.
This steel is widely used in completion equipment, in both bar form and for structural and pressure-containing components, especially in standard and CO₂ environments. However, factors such as pH, chlorides, temperature, and the presence of H₂S may limit its use in other environments.
The grade is NACE MR0175 approved, supplied to a hardness of 22 HRC, making it suitable for packers and other sub-surface equipment.

The "Super 13 Cr" family of martensitic stainless steels offers enhanced mechanical properties and greater corrosion resistance compared to standard 13 Cr or 420 Mod grades. The 95 KSI strength level is approved for NACE MR0175 applications under the current standard. Additionally, the low carbon content improves weldability compared to standard 13 Cr grades.
The 110 KSI strength level is also widely used, although some specific end-user approvals may be required for both strength levels.
This stainless steel is available in bar and tube form and is commonly used in completion equipment. Its primary application is in environments containing CO2, chlorides, and low concentrations of H2S.
