The difference between A36 and EN10025-4 S355M steel

Steel pipe EN10025-4 S355M steel manufacturing, environmental protection equipment and other manufacturers supply steel products, which have been well received by new and old customers. Steel sales have maintained a strong growth momentum and have achieved a good reputation in the steel industry. The EN10025-4 S355M steel company has a young, energetic and service spirit, high-quality management team.

Low-alloy structural steel plates are mainly used in machinery manufacturing and metal structural parts. Advantages of EN10025-4 S355M steel, low-alloy structural steel plates: They have superior performance and light weight. Disadvantages of low-alloy structural steel plates: These steel plates are all killed plates. The molten steel is deoxidized before the production. When the molten steel is poured into the ingot mold, its reaction is relatively calm and there will be no boiling state. EN10025-4 S355M steel, low-alloy structural steel plates price will be more expensive.

The wear-resistant layer of EN10025-4 S355M steel wear-resistant steel plate is mainly composed of chromium alloy, and other alloy components such as manganese, molybdenum, niobium and nickel are added. The carbide in the microstructure is distributed in the form of fiber, and the direction of the fiber is perpendicular to the surface. The microhardness of carbides can reach hv1700-2000 and HRC58-62 respectively. The alloy EN10025-4 S355M steel carbide has strong stability at high temperature, high hardness and good oxidation resistance. It can be used normally within 500 ℃.

Alloying agents like carbon and manganese along with steel lends a malleable nature to A572 structural high tensile steel plates, EN10025-4 S355M steel, letting them be formed into various structurals that adapt quickly to constantly evolving needs of an edifice, thereby being flexible to changes. High tensile steel plates facilitate an increased load bearing capacity; their lighter bodies handle the extra weight without giving in to pressures. Heavy lifting and moving vehicles built from them increase weight bearing capacity, reduce time and labour cost to increase profits.

The proportion of main elements in Q345 steel is basically the same as that in 16Mn steel, the difference is that V, Ti, Nb microalloy elements are added. A small amount of V, Ti, Nb alloy elements can refine the grains, greatly improve the toughness of the steel, and greatly improve the comprehensive mechanical properties of the steel. Because of this, the thickness of EN10025-4 S355M steel, Q345 steel plate can be made larger. Therefore, the comprehensive mechanical properties of Q345 steel should be better than that of 16Mn steel, especially its low temperature properties. The allowable stress of Q345 steel is slightly higher than that of 16Mn steel.

The high strength EN10025-4 S355M steel low alloy steel, which is shorten as HSLA steel, is one of our main products. We have professional team to serve you. For any demands or questions about HSLA steel, for example, ASTM A572 grade 50 chemical composition, difference between S355JR and S355J2, mechanical properties of EN10025-4 S355M steel ST52 steel, Q345B tensile strength, Q345D steel ASTM equivalent, HSLA steel price etc. , please do not hesitate to contact us and consult.
