What factors will affect the accuracy of laser cutting for S690QL bending

Our company's technical department is the core department of the whole company. There are a group of very professional technical personnel. They provide some architectural drawings according to the ideas of customers, and they are responsible for how to select the right materials. Including the evaluation of steel products such as multi steel plate, S690QL bending and steel pipe, grasp the whole production process, and strictly follow the production standards and customer quality requirements.

The carbon and low alloy steel plates are our main products. Our main conducted standards for carbon and low alloy steel plates are (ASME) ASTM (S)A36, (S)A283, S690QL bending, (S)A572, (S)A573, (S)A633, (S)A709, EN10025-2, EN10025-3, EN10025-4, EN10025-6, JIS G3101, JIS G3106, DIN 17100, DIN 17102, etc. Our typical carbon and low alloy steel grades are (S)A36, (S)A283 grade C, (S)A572 grade 50, S235JR, S355JR, S355J2, SS400, SM570, ST37-2, ST52-3, Q235B, S690QL bending, Q345B, etc.

In order to improve the S690QL bending corrosion resistance and decoration of steel, it is an important content of steel production method to plating or coating a protective layer on the surface of plastic processed steel. The material of protective layer is divided into metal and non-metal. The metal protective layer adopts the methods of electroplating, hot plating and chemical plating. The main S690QL bending coating metals are zinc, tin, copper, aluminum, chromium, etc., of which zinc plating and tin plating are the most common. Taking S690QL bending sheet metal as an example, there are many hot-dip galvanizing methods used in sheet metal galvanizing. Continuous hot-dip galvanizing is one of the main galvanizing methods used in the world.

Hardness comparison between Q345B steel and NM450 steel: wear resistant steel for construction machinery requires high wear resistance, high toughness, impact resistance, easy welding, easy forming and other high-performance characteristics. The main index of wear resistance is the surface hardness. The higher the hardness, the better the wear resistance. Compared with S690QL bending, Q345B steel, the hardness of NM450 steel is only increased 3 times, but the average service life is increased 6-8 times under the same working conditions.

As steel transportation belongs to the transportation of major parts, so in the process of transportation, modern logistics technology, such as centralized transportation, information technology, is a bit out of place. Based on the current situation of China's S690QL bending steel transportation industry, highway transportation is a way of transportation that many enterprises often choose. Naturally, its business volume also accounts for more than 50% of the whole S690QL bending steel transportation industry.

The high strength S690QL bending low alloy steel, which is shorten as HSLA steel, is one of our main products. We have professional team to serve you. For any demands or questions about HSLA steel, for example, ASTM A572 grade 50 chemical composition, difference between S355JR and S355J2, mechanical properties of S690QL bending ST52 steel, Q345B tensile strength, Q345D steel ASTM equivalent, HSLA steel price etc. , please do not hesitate to contact us and consult.
