Does any have information about what the lowest service temperature for Ti 6Al-4V spring temper material is?

Is it possible to Shotpeen a spring made of 0.0295" Beryllium Copper Rockwell 44-46C? If so can you reference a specification? Thanks

IRstuff, We are waiting for lab results ,so we do not have that info yet.

IRstuff, Yes the wire diameter after post plating failed the 0.026 +/-0.0003 spec. The wire diameter was measuring 0.0251 to 0.0258.

Thank you all for the input this has been very helpful

The vendor uses two cleaning solutions to prepare the surface for plating First Nuvat 6-8 oz/gal tank temp 160-180F Second Maxamp 8-10 oz/gal tank temp 160-180F I don't think the cleaning solutions would dissolve the material. Could there be a issue with the plating rectifier? Below are the...

IRstuff, Yes we have requested this information from the vendor.

Thank you all for the information I have learned something new today. I do have one more question. Would there be a physical change to the appearance of the material surface on the part if the acid cleaning was not done correctly?

CoryPad I was not aware of that. So what effects the remove amount? Would it be time in the bath and acid concentration? Thank you this really helps

IRstuff We measure the wire diameter cross section before and after plating using a micrometer using the same method. Tomwalz A pickling was performed to clean the surface before tinning. Thank you all

We manufacture a Compression spring out of 0.026" tolerance +/-0.0003 wire diameter music wire per astm A228. We send the part out for a commercial thk .12 mil min tin plate. Weird thing occurred when we received the parts back and measured the wire diameter cross section-ally the wire...

Thanks for the feed back that is a option we are discussing.

I have a technical question about a compression spring we make for a customer. The spring is made of 316SS spring temper per ASTM A313. The problem that occurs is the customer places the compression spring into a mold so the spring is under some compression, about 20% of the deflection and the...

Does anyone know what the industry standard tolerance is for the Concentricity of a compression spring.

Material: 0.014" Nitinol # 1 condition cold worked spring temper surface finish: etched and polished. type of spring compression spring closed ends not ground Looking for any online resources for manufacturing guidelines. Thanks
