ASTM A572: Temperature Effects on Yield

[FredGarvin]

Does anyone happen to know of a good reference for ASTM A572 (any grade) that lists temperature effects on yield? The standard only lists room temperature specs.

Thanks

Hi Fred,
You might want to try the structural steel forum at Eng Tips.

Hey Q. Good to see you.

Thanks. I keep forgetting about Engineering Tips. I'll float by there too. Thanks also for the thread link. Luckily I am not designing for a structure, in their sense. I have a very particular need for an I beam that definitely does not fall under the usual structural engineering umbrella.

For ASTM A572 Grade 42
http://www.matweb.com/search/DataSheet.aspx?MatID=14023

Four grades are avaiable - 42, 50, 60 and 65, which represent min RT YS in ksi. The material's strength depends on composition and thermo-mechanical processing (e.g. controlled rolling and accelerated cooling methods).

ASTM materials standards are intended to provide some specifications for manufacturing and product acceptance in order to assure quality and uniformity of product. The ASTM standards do not provide performance criteria or characteristics. That must be determined by the end user.

Thanks Astro.

I was looking at the composition and the properties of both the A572 and plain 1020, I am wondering if I couldn't just use the curve for 1020 yield suppression and call it a day. I am still waiting on my metallurgy guys to get back to me on this.
