Compared with the traditional seamless steel pipe, alloy seamless pipe has better performance in all aspects. Because of the addition of various metal elements in the manufacturing, the overall strength of the alloy seamless pipe is larger, stronger and durable, and the service performance and service life of the A36 steel strip, alloy seamless pipe are improved. The alloy seamless pipe is the best choice especially for special environment and high pressure requirements. Because of its high material properties, alloy seamless pipe has good corrosion resistance. It is not easy to be corroded in some special environment, which reduces the cost of the project and has a longer service life.
A36 steel strip, No. 55 steel delivery status: delivered in the state of no heat treatment or heat treatment (annealing, normalizing or high temperature tempering). If it is required to be delivered under heat treatment, it should be indicated in the contract. If it is not specified, No. 55 steel shall be delivered without heat treatment. Specification for heat treatment of No. 55 steel: normalizing, 820℃; quenching, 820℃; tempering, 600℃. Metallographic structure: sorbite.
With high-quality A36 steel strip steel and professional services, we have won international praise in infrastructure, shipbuilding, oil and other industries, and gradually grow into a bright star in the steel export industry, while winning unanimous praise from foreign customers. It has laid a foundation for the development of our A36 steel strip steel market and improved the control of steel plate production quality.
Large-thickness A36 steel strip, Z35 grade steel plate is a kind of extra-thick steel plate that is applied under specific environmental conditions, such as the key parts such as the turbine seat ring and guide vane of the generator set. It has high requirements for safety, reliability, and long service life. Develop 200mm-300mm thick steel plate of Z35 level, to ensure that the layer tear resistance reaches Z35 level. 300mm thick Z35 grade steel plate can be used not only in the hydropower industry, but also in the manufacture of other large key equipment, and has broad prospects.
