EN10025-4 steel S355M prices plunged

Our quality control department will do inspection for details of the steel materials EN10025-4 steel S355M before delivery. We would invite the customer side to attend the inspection together. If they can not come, we will also take rich pictures for them to check. Meanwhile, we will publish inspection report and send them the PDF version. Besides, we accept any third party inspection such as SGS, BV, etc. And our quality control department will support the third party to inspect the steel materials smoothly and try our best to deliver the qualified steel materials to customers earlier.

The weldability of EN10025-4 steel S355M is good. It means that under certain process and construction conditions, EN10025-4 steel S355M can obtain good performance after welding. Weldability is a measure of the hot workability of steel. Weldability can be divided into weldability in construction and weldability in use. Weldability in construction refers to the sensitivity of cracking in weld metal and near seam zone, and hardening sensitivity of steel in near seam zone. Good weldability means that under certain welding process conditions, the weld metal and steel near the seam do not produce cracks. Weldability in use means that the mechanical properties of weld and HAZ steel are not lower than those of base metal.

Chemical composition of 42CrMo seamless steel pipe: C: 0.38-0.45, Si: 0.17-0.37, Mn: 0.50-0.80, Cr: 0.90-1.20, Mo: 0.15-0.25, V: 0.15-0.30. Mechanical properties of 42CrMo seamless steel pipe: tensile strength: 1080 MPa, yield strength: 930 MPa, elongation after fracture: 12%, reduction of area: 45%, impact energy: 63J. Due to the effect of carbon and chromium content, EN10025-4 steel S355M, 42CrMo seamless steel pipe has better strength and hardenability, higher fatigue strength and resistance to multiple impact after quenching and tempering, good impact toughness at low temperature and no obvious temper brittleness. It is generally used after quenching and tempering.
