What is application of s355j2 density

Pakistan's iron and steel industry has suspended s355j2 density production and operation since the outbreak, the dawn reported on April 8. Last month, Prime Minister Imran announced a rescue package for the steel industry. Recently, Pakistan's steel industry called for the resumption of production as soon as possible. The Secretary General of the association of large s355j2 density steel producers in Pakistan said that steel is the pillar of Pakistan's construction industry, and Pakistan's economy cannot bear the consequences of the long-term closure of the steel industry. Any delay in the resumption of production will lead to the failure of the government's plan to revitalize the construction industry, which will have a negative impact on Pakistan's economy. It is hoped that the government will immediately resume s355j2 density production in the steel industry, especially those that are able to provide shelter for workers.

Our company will set up a full-time service engineer for the project, who is responsible for the interface and coordination of technical support and after-sales service of the s355j2 density project. In response process of customer service center, in case of technical support and after-sales service demand, the user shall contact the full-time engineer of s355j2 density customer service center, and the technical personnel will give corresponding answers and on-site treatment according to the needs of users.

The mechanical properties of 20MnV steel are as follows: tensile strength 785 MPa, yield strength 590 MPa, elongation after fracture 10%, reduction of area 40%, impact absorption energy 55 J. s355j2 density, 20MnV steel has good properties, good strength, toughness and plasticity, good hardenability and machinability. After carburizing, 20MnV steel can be directly quenched without secondary quenching to improve the core structure. The weldability of 20MnV steel is good, but there is temper brittleness at 300-360 ℃ during heat treatment.

In particular, the EU imports a large amount of iron ore from central and South America and Oceania, which are mainly transported by sea. The perfect port infrastructure makes the port operation cost of EU iron ore raw materials import relatively low. However, the s355j2 density steel transportation between EU Member States is mainly railway transportation, and the EU member states have established a very developed railway network and railway information infrastructure.

After hot extrusion, the grains of the alloy wear-resistant steel plate are significantly refined, dendrites and network structures are broken, and the grain size and the distribution of precipitated phases in the alloy are more uniform to generate Al2Y and Al3Y phases distributed within and along the grain boundaries , The hardness is significantly improved, the mechanical properties are significantly improved, the deformation strengthening effect is more significant, and the corrosion resistance of the s355j2 density, alloy wear-resistant steel plate is significantly improved.

The s355j2 density pressure vessel steel plates are our featured products. We have supplied pressure vessel steel plates to tank manufactures, boiler makers, power plants and so on customers all over the world. We have online service for you at any time, welcome to contact and learn more information about pressure vessel steel, such as s355j2 density ASTM A537 class 1 equivalent, 16Mo3 datasheet, Q245R material properties, Q345R material specification, P355GH properties, pressure vessel steel price, etc.

From the order to the delivery, there are three quality inspections to ensure that the qualified rate of finished products is more than 100%. We promise that every order will be tracked in a timely manner to ensure that customers can receive goods safely and constantly listen to their opinions and suggestions, reflect on our own problems, and let customers feel at ease.
