A516Gr70 Boiler Steel Plate

A516GR70 boiler steel plate is a type of steel plate widely used in the manufacturing of pressure vessels and boilers for medium and low-temperature applications. It possesses excellent mechanical properties, weldability, and machinability, capable of meeting the operational requirements of various pressure vessels under ambient and medium-low temperature conditions. The chemical composition of this steel plate primarily consists of carbon, manganese, and silicon, with trace amounts of phosphorus and sulfur. It undergoes normalizing or controlled rolling processes to ensure uniformity and stability of the microstructure. When welding this steel plate, the following points should be noted:

• Low-hydrogen electrodes are recommended
• Preheating temperature should be controlled between 100-150°C, with adjustments made based on thickness
• Post-weld hydrogen removal treatment is recommended, with a holding time of 2 hours at 250°C

When using A516GR70 boiler steel plates, the following key points must be observed to ensure safe and stable operation of the equipment:

Proper Storage
Upon receipt of the steel plates, the purchaser should store them in a dry, well-ventilated warehouse. Do not store them outdoors to prevent rusting caused by rain or moisture. When storing, maintain a certain distance from the ground to avoid direct contact that could cause corrosion. Steel plates of different specifications and batches should be clearly labeled and stacked separately.
Cutting and Processing
Steel plates can be cut using mechanical cutting or thermal cutting methods. During thermal cutting, control the cutting temperature and speed to prevent overheating, which can cause hardening or cracking of the plate edges. After cutting, remove any burrs from the edges to ensure dimensional accuracy meets design requirements.
Bending
When workers perform bending, rolling, or other forming processes on steel plates, appropriate process parameters must be selected based on the thickness and properties of the steel plate to avoid excessive bending that could cause material fracture or permanent deformation.
Welding
Before welding, oil, rust, moisture, and other contaminants must be removed from the weld joint and surrounding areas to ensure welding quality.
During welding, workers must strictly control welding parameters such as welding current, voltage, welding speed, and interpass temperature.
Safety and Maintenance
Users must regularly inspect the equipment surface for corrosion. If rust is detected, it must be promptly removed and treated with corrosion protection.
During processing, welding, and installation, operators must adhere to safety procedures and wear necessary protective gear to prevent accidents.
