Which is better A36S690QL heat treatment

For S420NL weldable fine grain structural steel plate, it is produced under specification EN 10025-3. The yield strength of S420NL plate shall be above 420Mpa for the thickness below 16 millimeter, 400MPa min. for thickness below 40mm, 390MPa min. for thickness below 63mm. The tensile strength for thickness below 100mm of this steel grade S420NL shall be within 520-680Mpa. For the Mill test certificates of steel S420NL,S690QL heat treatment, our mill would like to issue format according to EN 10204 3.1.

Wear-resistant steel plate is a kind of construction material with good wear resistance and high toughness. S690QL heat treatment, wear-resistant steel plate plays an important role in many industries in daily use. However, what is wear-resistant steel plate? Where is it used? The wear-resistant layer is the main component of the wear-resistant steel plate. The material used to make the wear-resistant layer is mainly titanium alloy. In addition, other materials such as manganese, nickel, molybdenum, and niobium may be added. The coordination of all materials is to maintain or enhance the wear resistance of the wear layer.

Both the cross rolling method and the extrusion method must first heat the tube blank or ingot, and the steel tube produced is called hot rolling tube. Steel pipes produced by hot working can sometimes be cold worked as required. There are two methods of cold working: one is cold drawing, that is, drawing the S690QL heat treatment steel pipe through the drawing die to make the steel pipe gradually thin and elongate; the other is cold rolling, which is the method of applying the hot rolling mill invented by the menesmann brothers to cold working. The cold working of S690QL heat treatment seamless steel pipe can improve the size accuracy and finish of steel pipe, and improve the mechanical properties of materials.

After-sales service is an important part of measuring a product good or not. After sales service can't be ignored. Good service can really make consumers feel relieved. We have always done a good job in after-sales service, so as to bring consumers a better reference when purchasing and a better experience during use of our steel materials. We will call back and follow up the performance of our steel products regularly.
