Inquiry About Shanghai Changzeng Metal Co., Ltd.2019-06-05 09:36:27
Good afternoon

I work at T2 Design in Santa Monica and we designed a FLAT spring of 
64mm height, 96mm width and 1.52mm thickness, 
AISI 4340 NORMALIZED with zinc plating finish for a prototype. 
Only one flat spring will be required for the initial prototype.

We are looking for a company that can machine it and/or provide us the material. 
It must also give us a Material Test Report or a Certificate of Conformance of it because we will need the material to be close to our proprieties/specifications for the product to function.

The most important thing about the material is to have a high YIELD strength (more than 650MPa) and IF POSSIBLE a fair corrosion resistance. 

IF YOU HAVE ANOTHER SUGGESTION FOR A BETTER MATERIAL, IT IS VERY WELCOME.

Do you make this kind of work? If so, could you please provide a price estimate? 
If your company do not machine or sell this kind of steel, do you know who can?

Thank you
