Our company is China's 10th largest supplier & Exporter of stainless steel, carbon steel plate and section, alloy steel plate and pipes. We are specialized in stocking & distributing various Stainless Steel, carbon steel plates, EN 10149-2 steel grade S420MC angle steel, H beam steel to worldwide for specific & urgent requirements. We have a fully advanced and modernized warehouse that stores tonnes of our value-adding en 10149-2 steel grade s420mc products, which we source out from the mills that are compliant with the universal guidelines for plate production.

The difference between q345 and q235 steel en 10149-2 steel grade s420mc
The lower limit of yield strength of Q345 is 345MPa (the actual meaning of Q is the Chinese character ""qu"", and the standard value behind means the lower limit of yield strength). Q235 steel is used for metal structural parts, nitrided or cyanidized parts with low core compressive strength requirements, support rods, crankshafts, crane hooks, couplers, bolts and nuts, sleeve specifications, shafts and weldments.

The wear-resistant plate en 10149-2 steel grade s420mc shows good wear resistance: the chemical composition of the alloy layer contains 4-5% carbon and 25-30% chromium. The volume fraction of Cr7C3 carbide in the metallographic structure is more than 50%, the macro hardness is HRC56-62, and the hardness of chromium carbide is HV1400-1800. Because of the vertical distribution of carbides in the wear direction, the wear resistance of the cast alloy with the same composition and en 10149-2 steel grade s420mc hardness is more than twice as that of the cast alloy with the same composition and hardness. Compared with several typical materials, the wear resistance is as follows: (1) compared with low carbon steel; 20-25:1 (2) with as cast high chromium cast iron; 1.5-2.5:1.

The adhesive wear of en 10149-2 steel grade s420mc, wear-resistant plate refers to the relative sliding of the contact surface between the workpiece and the workpiece. Due to the effect of solid-phase welding, the adhesive point is separated from the material matrix and transferred from one surface to another under the effect of shear force, resulting in the wear of the workpiece. Abrasive wear of wear-resistant plate refers to the phenomenon that external hard particles make the surface materials fall off in the process of friction and wear. There is also a case that there are hard convex particles on the surface of the workpiece, which can also play the role of abrasive in the process of friction and wear, resulting in surface spalling.

en 10149-2 steel grade s420mc, St52-3 steel is a low alloy, high strength structural steel which can be readily welded to other weldable steel. St52-3 steel’s mechanical properties is yield strength more than 355 MPa, tensile strength 490-630Mpa. For St52-3 steel, the C element content is 0.24%, the Si element content is 0.55% max, the Mn element content is 1.60% max, the P element content is 0.045% max, the S element content is 0.045% max.

The company has a high-quality management, technology and R&D team, and adopts independent research and development, domestic innovative process optimization combination. Relying on advanced manufacturing technology and sophisticated production testing equipment, it has ensured the high quality of products en 10149-2 steel grade s420mc and won a good reputation. We can offer various kinds of steel materials in GB, ASME, ASTM, JIS, DIN, EN, API standards and specifications.

The company formulates clear service process and service standard. To do a good job in after-sales service, first of all, clear service process and service standards should be formulated to let employees know which procedures to perform and which service standards to abide by.
