What is the difference between ordinary carbon steel and en 10149-2 high yield strength alloy steel s420mc

The company now has en 10149-2 high yield strength alloy steel s420mc oversea market department, sales and supply department, finance department, logistics department, technical equipment department, quality management department, production department an

The company now has EN 10149-2 high yield strength alloy steel S420MC oversea market department, sales and supply department, finance department, logistics department, technical equipment department, quality management department, production department and other departments. The staff with college degree or above accounted for more than 80%, and there were more than en 10149-2 high yield strength alloy steel s420mc 30 professional and technical personnel. The LSAW pipe production line can produce welded pipes with Φ350-1800mm, wall thickness 6-80mm, and length 2-12m.

VLE460 steel plate grade analysis: "VL" stands for the abbreviation of "DNVGL", which is the standard certified by the two classification societies of DNV (Norway) and GL (Germany). VL E460 hull steel characteristics: good welding and other properties. It is suitable for repairing ships and main structures of naval vessels. Naval steel is required to have higher strength, better toughness, blast resistance and resistance to deep water collapse.

In the face of domestic and foreign steel situation, based on the advantages of production and inventory, we have established our own processing center, and our manufacturing includes different types. Steel en 10149-2 high yield strength alloy steel s420mc surface treatment - such as steel pretreatment (shot peening and shop primer), steel galvanizing; steel structure processing - such as cutting, drilling, milling, turning, bending, welding, etc.

With the increase of temperature, the yield limit of en 10149-2 high yield strength alloy steel s420mc will decrease monotonically, but the tensile strength of en 10149-2 high yield strength alloy steel s420mc will rise to a high peak value at a certain temperature, and then decrease. This peak temperature is called the blue brittleness temperature of en 10149-2 high yield strength alloy steel s420mc. Near the blue brittleness temperature, the en 10149-2 high yield strength alloy steel s420mc strength increases and the plasticity decreases. The elongation and section shrinkage of en 10149-2 high yield strength alloy steel s420mc increase with the increase of temperature, but there is a low peak at the blue brittleness temperature. The blue brittleness temperature of low carbon steel ranges from 200 ℃ to 250 ℃. The blue brittleness of low alloy steel is not obvious as that of low carbon steel, and the blue brittleness temperature is higher.
