Substituting Metals

Check the application, there seems to be some difference in mech properties

YS 300 for DIN EN 10025 S235J (195-235)

TS 440 (350-510)

%E 22 (22-26)

Charpy 30 @50⁰C (27 @20^oC)

Use if your design permits these values .

Your material falls in between S275 and S355.

Check this. it may help you

Thank you sir.May i know what is your profession

Hi, dinakrj!

I'm in complete agreement with sb.

The application will determine whether two different alloys are similar enough to be employed, not their designation numbers.

Look them up, and determine whether they are similar enough from the point of view of the application (strength, corrosion resistance, reluctance, mutability, etc.) to be interchangable in yours.

What's your application going to be?

No simple answer.

It is just a support

Hi dinkarj!

I guess it's you telling me what the use of the alternative metal piece will be, since you would be the one to know, even though you show up as "guest".

Well then, bearing load related to compression (or tensile if forming a support beam) strength for starters. Keep saftey margins in mind.

Straight or bent beam or bracket or brace if you need to go to those extremes for length/size/load calculation.

Appropriate galvanic reaction times compared to supported item or shielding (if necessary) and fasteners with appropriate sheer strength to avoid galvanic response between new piece and fasteners.

It all takes just a few minutes, and probably when you know the answers, you can adjust the dimensions of the second alloy to match the strengths required in the first in case it is not sufficiently strong for its intended use with the same dimensions and install it with good life expectancy.
