Hot Rolling and Flaw Detection of S420ML steel plate
Perhaps you know what kind of material S420ML is, but do you know any knowledge about hot rolling and flaw detection of S420ML?
Hot rolling of S420ML steel plate:
S420ML is usually delivered in hot-rolled state, while S420ML can produce several common finished forms such as wire rods, round bars, square steel, and steel pipes. In this article, the hot-rolled plate refers to S420ML steel plate. Generally speaking, the surface of hot-rolled plates is relatively rough, but they have good strength and toughness, that making them suitable for the requirement of strength and wear resistance.
Flaw detection of S420ML steel plate :
The flaw detection of S420ML steel plate should be carried out according to the European standard and the German flaw detection standard, or according to the flaw detection standard of national standard.
For flaw detection, national standard requires more strictly than the German and the European standard. So, the last two standards are commonly used for the flaw detection of S420ML steel plate with a thickness above 200mm.
