What is requirement for surface of SPA-C normalized

SPA-C normalized,Our company's power boilers, heating furnaces of double bars, double high lines and medium and thick plates all adopt heat storage technology, which can fully use blast furnace gas; the ladle baking, Maerz active lime kiln and medium and thick plate heat treatment furnace all burn converter gas, which can improve the utilization rate of secondary energy and realize negative energy steelmaking in steelmaking process.

SPA-C normalized,At present, China's wear-resistant steel plate grades are divided into six levels, namely NM300, NM360, NM400, NM450, NM500, NM550 and NM600. The wear-resistant steel grade adopts the combination of Chinese NM of wear resistance meaning and Brinell hardness (HB) value. For example: NM500, NM is the first universal parent of Chinese "wear resistance", "500" is Brinell hardness value. NM series wear-resistant steel has good wear resistance, which greatly reduces the loss and use cost.

The application of AR400 abrasion resistant steel plate: SPA-C normalized, AR400 abrasion resistant steel plate is mainly for wear exposed structures use, such as protective pads, shell walls for prospectors and bulldozers. AR400 abrasion resistant steel plate is also used to fabricate the supporting or reinforcing plate, the cutting plate for truck rollover, mixing elements and conveying elements, chute grooves, machine tools, crushers and shredders, waste briquetting presses, blades, paving abrasives and agricultural machinery.

SPA-C normalized,Ultrasonic flaw detection emits ultrasonic waves to the steel plate under inspection. If there are defects in the steel plate, the ultrasonic waves will reflect, refract or deform waveforms due to the defects. By recording these changes, the type and shape of the defects are analyzed. Due to its high energy and good penetration performance, and the smoothness of the steel plate itself, ultrasound is often used to detect defects such as inclusions, shrinkage holes, bubbles, and cracks in the steel plate.

Q355GNH weather resistant steel plate is one of our main product, it is belong to the weather resistant steel plate. We can supply the different sizes of Q355GNH weather resistant steel plate. And the rolling size of Q355GNH weather resistant steel plate is following: the thickness range is 1.2-150mm, the width range is 1220-4200mm, and the length range is 5000-18000mm. Also note that the Q355GNH weather resistant steel coil thickness should not exceed 25 mm.
