We work with carbon steel, stainless steel, duplex stainless steel, alloy steel, brass, aluminum and titanium. Common stainless steel grades include 304, 304L, 316, 316L, 904L, B8 and B8M. The available grade depends on the product and application.

9. What product standards do you support?

We manufacture according to internationally recognized standards including ISO, DIN, ANSI/ASME, BS, JIS, GB and ASTM. We can also manufacture according to customer-specific standards when the technical requirements are confirmed.

10. What strength grades are available?

Available grades include carbon steel grades 4.6, 4.8, 5.8, 6.8, 8.8, 10.9 and 12.9; stainless steel grades A2-70, A2-80, A4-70 and A4-80; and alloy steel grades such as B7, B7M, L7 and L7M. Please specify the required grade in your inquiry.

11. What thread systems do you support?

We support metric threads, imperial UNC and UNF threads, and customer-specific thread requirements. Please provide the thread designation, diameter, pitch or TPI, length and tolerance in your drawing or inquiry.

12. What thread tolerances can you produce?

Our standard thread tolerance is generally 6g for external threads and 6H for internal threads. Other tolerances, such as 4H, 5H, 5g, 6e and 6f, can be discussed according to the application and drawing requirements.

13. What surface treatments and coatings are available?

Available treatments include zinc plating, hot-dip galvanizing, black oxide, nickel plating, chrome plating, tin plating, Dacromet, Geomet, passivation and phosphating. The suitable treatment depends on the material, environment, corrosion requirement and applicable standard.

14. Can you produce tight dimensional tolerances?

Yes. We can produce parts with specified dimensional and thread tolerances using precision machining and inspection equipment. Please include the critical dimensions, tolerance requirements and inspection standard in the technical drawing.

15. Can you provide technical drawings?

Yes. We can provide 2D or 3D technical drawings for standard products. For custom products, our engineering team can prepare drawings based on your specifications or samples and confirm them with you before production.
