JIS SG295 steel plate for boiler applications

The ASTM/ASME SA516 JIS SG295 steel plate specification covers carbon steel plates, which are mainly used for welding pressure vessels, where improving notch toughness is very important. The JIS SG295 steel plate tensile strength range is 55-90MPa, and its versatility makes this specification very popular in applications.

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 JIS SG295 steel plate 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.

Non-destructive flaw detection of steel plates is a test method for inspecting the JIS SG295 steel plate surface and internal quality of the inspected parts without damaging the working state of the workpiece or raw materials. Commonly used JIS SG295 steel plate steel plate flaw detection methods include: X-ray flaw detection, ultrasonic flaw detection, magnetic particle flaw detection, penetration flaw detection, eddy current flaw detection, gamma-ray flaw detection, fluorescent flaw detection, color flaw detection and other methods. Physical flaw detection is non-destructive flaw detection without any chemical changes.

Boiler steel is different from JIS SG295 steel plate. Boiler steel is used to make boilers. Boiler steel can be divided into steel for boiler steel pipe, boiler steel plate and boiler steel fasteners. Boiler steel is smelted by open hearth furnace, converter, electric furnace, and some also use the refining process outside the furnace. Boiler steel for steel pipes refers to the steel used for the manufacture of superheaters, reheaters and headers. Their working temperature is higher than other parts, and the environment is also harsher.

The company formulates clear service process and service standard. To do a good job in after-sales service, first of all, clear service process and service standards should be formulated to let employees know which procedures to perform and which service standards to abide by.
