EN steel grade S235J2 material tolerance and delivery state

For low alloy high strength steel, the addition of small amounts of V, Ti, Nb, AI and other grain refining elements not only further improves the strength, but also improves the toughness of the steel. In EN steel grade S235J2 material, low alloy high strength steel, rare earth element Re is sometimes added to eliminate harmful impurities in the steel, improve the shape and distribution of inclusions, and weaken its cold brittleness. A small amount of alloying elements has a significant effect on improving the mechanical properties of steel. For example, adding only 1% Mn to Q235 becomes Q345 steel, but its strength increases by nearly 40% to 345 MPa.

The overall intention of supporting prices in the raw material market is relatively strong, but the steel mills have a low acceptance of high prices, and some just need a small amount of goods, so the overall market game state is obvious. With the poor release of steel demand, terminal merchants tend to consume low-cost inventory in the early stage and purchase on demand to avoid the risk of large-scale hoarding. However, the cost side is weak, and some EN steel grade S235J2 material manufacturers secretly reduce prices to promote transactions. It is expected that the EN steel grade S235J2 material market will be stable and weak in the future.

From the name, we can clearly know that seamless pipe is seamless steel pipe, which is different from welded pipe. Seamless pipe is actually a kind of steel with hollow section. EN steel grade S235J2 material, Seamless pipe has many advantages, such as: 1, the compressive capacity of seamless pipe is very good, the place with high bearing strength will not crack, and its bearing capacity is very good. 2. Seamless pipe has no welding point, so it is more corrosion-resistant and can bear larger pressure.
