Frequently Asked Questions

1. What are the primary benefits of 17-4 PH stainless steel? It offers an excellent combination of high strength, good corrosion resistance (comparable to 304), and simple heat treatment processes to achieve various hardness levels.

2. What is the maximum size of forged bars you can produce? We can produce forged round bars with an outside diameter (OD) from 150mm up to 1000mm, and lengths up to 12,000mm.

3. How do you ensure the quality of your forgings? We conduct strict quality control including raw material chemical analysis, non-destructive testing (UT/MT), mechanical property tests, and precise size/hardness inspections before shipment.

4. Can the material be customized for specific mechanical properties? Yes, through different heat treatment cycles (annealing, solution, and aging), we can adjust the tensile strength and hardness (HRC 30-45) to meet your specific requirements.

5. Which industries commonly use your forged steel products? Our products are widely used in petroleum machinery, aerospace components, medical device manufacturing, chemical processing, and heavy hydraulic systems.

6. Do you provide international shipping? Yes, we have over 20 years of export experience and have shipped to more than 80 countries, including the USA, Europe, South America, and the Middle East.
