Sheet and Coil Stock Material Data 1

[Tippaporn]

Hi,

Not sure if I'm placing this post in the appropriate forum so if there's a more suitable forum please advise.

I'm looking for material data on a wide variety of materials used in metal stampings; stainless steels, beryllium copper, Series 1000 cold rolled steel, galvanized, bronze, phospur bronze, brass, etc. The specific data I'm looking for would be material density, tensile strength, yield strength and average yield strength. Also, these values for those particular materials where various hardnesses are applicable.

I'm developing a comprehensive engineering calculator in an Excel workbook which contains almost every imaginable formula for calculating, among many other things, forming, stripping, cutting and compression pressures, and accurate piece part weights. This workbook is to be used specifically for tool & die design engineering, for which there is no applicable forum here.

The purpose of collecting accurate materials data is so that I can create a materials table. I could then create a separate material sheet where material type, hardness and thickness is input using drop-down list boxes for easy selection. All of the required relevant material data used in these numerous calculations would then be automatically entered into the appropriate cells on each worksheet. This would eliminate manual multiple entries and the need to look up specific material data for each and every job.

Also, I'd like to enquire about "Average Tensile Yield Strength." This particular data is required to calculate forming pressure and yet I cannot find this data listed under a specific material's mechanical properties. How can I obtain this value?

For any help thanks in advance,

MatWeb has most of what you want:

Regarding "Average Tensile Yield Strength", I think that is the average of the tensile and yield strengths. I have seen that used as a basic estimate for pressure calculations.

Thanks for the reply, Cory.

I do use MatWeb but my problem here is pinpointing specific material from the information I am supplied with by my customers; material specifications usually called out in the piece part print.

For instance, 070 XLF HSLA, or CEMS A-6 Grade 1. For these two material types MatWeb's database pulls up either null or bar and round stock rather than sheet. Unfortunately, I do not possess an in-depth knowledge of materials and to a novice it's rather confusing. For one, I'm not entirely sure that mechanical properties for bar and round stock would be applicable to sheet.

Thanks, also, for the explanation of "Average Yeild Strength." At least it appears I could calculate the value myself then.

If you must meet the requirements of standards, then you need to obtain those standards. You are correct that this can be a confusing, even overwhelming subject. You have gone as far as MatWeb can take you - now, you need to gain expertise with the standards.

Thanks again, Cory. Would you be able to suggest sources for obtaining standards? And possibly suggesting which standards I would need? I have a feeling that these will be expensive?

Global Engineering Documents has many of the world's consensus standards available for sale. Otherwise you need to obtain them directly from the various standards organizations (ASTM, ISO, etc.). Yes, it will be expensive to obtain the standards, but at some point that is the cost of doing business.

 

[CoryPad]

The standards bodies themselves have Internet sites for their standards.

The biggest ones for materials are ISO, ASTM, SAE.

http://www.iso.org

http://www.astm.org

http://www.sae.org

Also, you can go to a third-party who can provide standards from several organizations. The best is Global Engineering Documents:

http://www.global.ihs.com

You need to decide which ones are best, although maybe your customers are the ones specifying the materials/standards. As far as costs, ASTM standards are relatively inexpensive, SAE a little more expensive, and ISO very expensive. However, I think you get what you pay for. ASTM standards in general only provide basic information and are tailored for materials producers so that they can produce just about any material and meet the standard's requirements. On the other hand, ISO standards (especially those based on German DIN standards) are written more from the end users perspective and generally have more requirements for the materials.

Good luck.
