Product Introduction

NM400 Abrasion Resistance Plates

NM - The first letter of the Chinese Pinyin 400 is the Brinell hardness value HB value for wear-resistant and abrasive uses. NM400 is a wear-resistant steel plate with quite high mechanical strength; The mechanical properties of NM400 are 3 to 5 times that of ordinary low-alloy steel plates; The surface hardness of NM400 products usually reaches 360 ~ 450HB. Used in mining and various construction machinery for wear-resistant parts processing and manufacturing and other suitable structural steel plate.

1. Why does the steel plate need non-destructive testing?

Steel plate pass rate is not 100, there will be defects, steel plate inspection is not inspection mainly depends on the use of the place to see the regulations, if like aerospace and navigation, pressure vessels and storage tanks, energy, Bridges and other industries need to ensure the quality of steel plate.

If the number of steel plates is small, you can use the ultrasonic flaw detector manual detection, if it is a steel plate enterprise or the use of steel plate ultrasonic automatic flaw detection equipment is convenient. Primary inspection has high basic requirements for welding quality and plate, and secondary and tertiary inspection relatively lower requirements, because the boiler has the sealing and pressure resistance properties that must be possessed, so the welding holes and cracks of the boiler container plate inspection plate are an important part of the inspection. Wugang container plate can protect the flaw detection.

2, the type of flaw detection

Detect cracks or defects in metal materials or components. The commonly used inspection methods are: X-ray inspection, ultrasonic inspection, magnetic particle inspection, penetration inspection, eddy current inspection, gamma ray inspection, fluorescence inspection, color inspection and so on. Physical testing is non-destructive testing without chemical changes.

Non-destructive testing is a test means to check the surface and internal quality of the inspected part without damaging the working condition of the workpiece or raw material.
