Steel Q345R (HIC) is a Q345R pressure vessel plate with hydrogen induced cracking resistance test. Q345R(R-HIC) plate is based on Q345R (HIC) and SSCC test, namely sulfide stress corrosion test. The delivery status of Q345R (HIC) and Q345R Q345R(R-HIC) plate is normalizing, - 30 ℃ impact, level I flaw detection, process reference standard GB713-2014. A633 Grade A high-strength low-alloy structural steel, Q345R (HIC) and Q345R (R-HIC) plates are smelted by electric furnace + refining outside the furnace. The smelting process is Ca-treated, and should be intrinsically fine-grained steel. The actual grain size is 5 or above.
Nowadays, transportation is an important factor in economic development. Our company's rapid development is also inseparable from a good geographical location. The company is located in Zhengzhou, an important A633 Grade A high-strength low-alloy structural steel heavy industry area in Central China. Whether you are in Beijing, Shanghai or Guangzhou, you can visit our company very easily. My factory is nearby, convenient transportation and time saving.
First to determine the welding methods, such as hand arc welding, submerged arc welding and tungsten argon arc welding, melting polar gas shielded welding machine, and so on are very many different kinds of A633 Grade A high-strength low-alloy structural steel welding method, can only be chosen according to specific situation, determine the welding method, and make welding process parameters, different kinds of welding process parameters, such as manual welding mainly includes: electrode model (or brand) diameter, current, voltage, welding power source type and polarity connection, welding layer number, number, inspection method, etc.
Large-thickness A633 Grade A high-strength low-alloy structural steel, 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.
Our company has established and constantly improved the customer service system and emergency response system. Through the customer service management system, we track the service of the after-sales service team and provide efficient and standard services in time. At the same time, the company formulates a regular return visit system, compares the historical cases of customer problems, proposes a pre solution, and ensures that the service is in place in a short time.
