Our quality control department will do inspection for details of the steel materials EN 10149-2 S420MC equivalent 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.

Automobile steel plates are mainly used to manufacture automobile beams (longitudinal and transverse beams), frame and other structural parts. Automobile beams not only have to withstand heavy static loads, but also withstand certain impacts, vibrations. Therefore, en 10149-2 s420mc equivalent, automobile steel has certain strength and fatigue resistance, and require good stamping performance and cold bending performance to suit cold punching molding processing requirements.

Mechanical properties of 45# steel high-quality carbon structural steel: Tensile strength σb (MPa): ≥600, yield strength σs (MPa): ≥355, elongation δ5 (%): ≥16, section shrinkage ψ (%): ≥40, impact energy Akv (J): ≥39. 45# steel impact toughness value αkv (J / cm2): ≥49 (5), hardness: unheated, ≤229HB; annealed steel, ≤197HB. en 10149-2 s420mc equivalent, 45# steel chemical composition % (Carbon: 0.42 to 0.50, Silicon: ≤0.40, Manganese: 0.50 to 0.80, Sulfur: ≤0.045, Phosphorus: ≤0.045, Chromium: ≤0.40, Nickel: ≤0.40, Molybdenum: ≤0.10).

TMCP process is an indispensable technology for our production of low alloy high strength wide and en 10149-2 s420mc equivalent thick steel plates. TMCP process can produce steel with high strength and toughness without adding too many alloy elements and complex subsequent heat treatment. TMCP is a process that can save alloy en 10149-2 s420mc equivalent and energy and is beneficial to environmental protection. A lot of our shipbuilding steel plates are produced by TMCP process.
