Yield strength,tensile strength and elongation testing for German project

In order to guarantee good quality of material and issue EN10204 3.2 certificate,our company test yield strength,tensile strength and elongation in laboratory,BV witness the testing.The main material is A420 WPL6,A350 LF2 and 304L.

These tests are destructive.Prior to test,we prepare sample pieces according to heat number.

Yield strength,tensile strength and elongation are like three brothers

Yield strength is first,what is yield strength?

Yield strength is the material property defined as the stress at which a material begins to deform plastically.

Tensile strength is second.What is tensile strength?Tensile strength is the point when the material is broken.

What is elongation?After tensile strength testing,we will measure the length of sample,elongation is how much broken sample longer than before.

Our laboratory test all samples one by one, the result is excellent!
