17-7PH Stainless Steel Plate Price Per kg

With the continuous increase in demand for ultra-high-strength precipitation-hardening stainless steel plates in the aerospace, high-end precision machinery, and military equipment fields, the price of ASTM A693 17-7PH stainless steel plates has increased.The price varies depending on the purchase quantity, customized thickness, and heat treatment process. As a buyer, you should keep up-to-date with product price trends!

 

🔹What is 17-7PH stainless steel plate?

17-7PH is a precipitation-hardening martensitic stainless steel plate (UNS S17700) that conforms to ASTM A693 and AMS 5643 standards. It achieves excellent mechanical properties through controlled heat treatment under H900, H1025, and H1150 conditions, with tensile strength reaching up to 1200 MPa. Due to its combination of strength and durability, 17-7PH stainless steel plate is widely used in critical applications such as aerospace components, chemical equipment, mold parts, springs, and high-stress structural components.

 

🔹17-7PH Stainless Steel Plate Price per Kg

The price per kg of 17-7PH stainless steel plates depends on several factors:

Typical Price Range:

Raw material level: USD 8 – 12 per kg

Finished, heat-treated plates: USD 10 – 18 per kg

Factors Affecting Price:

Chemical Composition & Alloy Surcharge – High nickel and copper content increases cost.

Plate Thickness and Size – Thicker or larger plates cost more per kg due to higher material usage and processing.

Heat Treatment Condition – H900 (highest strength) commands the highest price; H1025/H1150 slightly lower.

Surface Finish – Polished or brushed surfaces require additional processing, increasing the price.

Standards & Certification – ASTM, AMS, ISO, SGS certified plates may have higher per kg pricing but ensure compliance and quality.

💡 For international buyers, shipping, import duties, and minimum order quantities also impact total cost.

 

🔹Applications of 17-7PH Stainless Steel Plate

Aerospace Components: Landing gear, structural parts, springs

Chemical Industry: Equipment exposed to mild acids

Mold and Tooling: High-stress molds, dies, and punches

Marine & Industrial: High-strength parts in less aggressive chloride environments

 

 

🔹How to obtain the best price per kilogram for 17-7PH stainless steel plates?

1. When requesting a quote, please be sure to specify the exact thickness, dimensions, and heat treatment process.

2. Request a Material Test Certificate (MTC) to ensure the material meets the required standards.

3. Compare prices and production capabilities from multiple suppliers.

4. Consider bulk ordering to reduce the cost per kilogram.

5. Check if the supplier provides packaging and relevant certifications that meet export standards to ensure smooth international shipping.
Buyers should focus on the total project cost, not just the price per kilogram. Choosing the right grade of material can save money in the long run due to reduced material usage and maintenance costs.
