Effect of alloy elements on mechanical properties of EN10025-4 S275ML steel plate

The company has allocated special environmental protection facilities for all EN10025-4 S275ML steel plate pollution sources, strengthened the recycling of waste resources and improved the efficiency of resource utilization. At present, the recovery and utilization rate of solid wastes such as iron slag, steel slag, iron bearing dust, EN10025-4 S275ML steel plate steel mill scale, environmental protection dust has reached 100%.

ASTM A36 and JIS G3192 steel angle EN10025-4 S275ML steel plate is one of the most widely used carbon steel section in the construction industry and project. It is a low-cost material and shows the required strength property compared with other steels. It is popular also for its good weld performance, formable, and easy EN10025-4 S275ML steel plate machining. Galvanizing and other treatment increases its resistance to corrosive environment.

Cold rolled coil products EN10025-4 S275ML steel plate have accurate size and uniform thickness, and the thickness difference of coil is generally less than 0.01-0.03mm or less, which can fully meet the requirements of high precision tolerance. The surface quality of cold rolled products EN10025-4 S275ML steel plate is superior, and there are no defects such as pockmarks, pressing iron oxide scale and so on, which often appear in hot rolled coils. According to the requirements of users, coils EN10025-4 S275ML steel plate with different surface roughness can be produced (glossy surface or matte surface, etc.).

The mechanical properties of EN10025-4 S275ML steel plate, boiler pressure components steel include strength, plasticity, toughness and fatigue properties. Temperature has a great influence on the mechanical properties of steel. With the increase of temperature, the yield limit of all kinds of steel will monotonically decrease, but the tensile strength will rise to a high peak at a certain temperature, and then decrease.

The difference of chemical composition between EN10025-4 S275ML steel plate, Q420D steel and Q460D steel: Chemical composition of Q420D steel: C ≤ 0.20, Si ≤ 0.50, Mn ≤ 1.70, P ≤ 0.030, S ≤ 0.025, Nb ≤ 0.07, V ≤ 0.20, Ti ≤ 0.20, Cr ≤ 0.30, Ni ≤ 0.80, Cu ≤ 0.30, N ≤ 0.015, Mo ≤ 0.20, Al ≥ 0.015. Chemical composition of Q460D steel: C ≤ 0.20, Si ≤ 0.60, Mn ≤ 1.80, P ≤ 0.030, S ≤ 0.025, Nb ≤ 0.11, V ≤ 0.20, Ti ≤ 0.20, Cr ≤ 0.30, Ni ≤ 0.80, Cu ≤ 0.55, N ≤ 0.015, Mo ≤ 0.20, B ≤ 0.004, Al ≥ 0.015. The difference of mechanical properties between EN10025-4 S275ML steel plate, Q420D steel and Q460D steel: The mechanical properties of Q420D steel: yield strength ≥ 420 MPa, tensile strength 500-680 MPa. The mechanical properties of Q460D steel: yield strength ≥ 460 MPa, tensile strength 500-720 MPa.
