DIN 17100 ST52.3 PIPES

High-strength DIN 17100 ST52.3 Pipes manufactured for superior performance in structural, mechanical, and industrial applications. These pipes offer excellent tensile strength, durability, and resistance to pressure, making them ideal for construction, fabrication, oil & gas, and engineering projects. Manufactured using quality-tested raw materials, our ST52.3 pipes ensure dimensional accuracy, smooth finish, and long service life while meeting international quality standards. Suitable for demanding industrial environments and custom requirements.

DIN 17100 ST52.3 PIPES

EN 17100 St52.3 has the following chemical composition requirements:

Grade	Chemical composition in % by wt.
	C						P	S	Additional nitrogen combining elements (e.g. at least 0.020 % Al to tal)
	for product thickness in mm
	≤16	＞16 ≤30	＞30 ≤40	＞40 ≤63	＞63 ≤100	＞100
EN 17100 St52.3	0.20 max	0.20 max	0.22 max	0.22 max	0.22 max	by agreement	0.040 max	0.040 max	yes

The chemical composition of St52.3 is measured by a spectrometer, and all element contents meet customer requirements compared to applicable requirements.

The mechanical properties of EN 17100 St52.3 mainly include tensile strength and yield strength, which are measured by tensile testing.
