S690QL rockwell hardness exported to Vietnam

The cold rolling precision bright pipe system produced by our factory has smooth appearance, uniform wall thickness, no oxide layer and high precision. The inner hole of S690QL rockwell hardness steel pipe can be divided into round, spline and plum blossom, which is widely used in automobile, motorcycle, electric power, petrochemical, ship, aerospace, bearing, pneumatic components, oil cylinder, boiler equipment, medical equipment, fitness equipment and other industries. Materials can be divided into: 10#, 20#, 35#, 45#, 40Cr, 16Mn, etc. According to the needs of users, we can make all kinds of national standard non-standard precision pipes. Special S690QL rockwell hardness materials and specifications can be ordered in advance.

The material used for the elbow is carbon structural steel or high-quality carbon structural steel 20#. These two materials can not only ensure that the carbon steel elbow has good hardness, strength and wear resistance, but also ensure the plasticity of the elbow, and ensure that the elbow will not be broken or wounded due to stress during forming. However, cast steel elbows are also used in some special piping systems. This type of piping system requires high mechanical properties of the elbow, and it is difficult to form by forging and other methods in the process.

304 stainless steel plate products have strong corrosion resistance. For ordinary alkali solution and organic acid, inorganic acid has good corrosion resistance. This material S690QL rockwell hardness is a high alloy steel, which can resist corrosion in air or chemical corrosive medium.

Penetration testing technology is only suitable for detecting surface defects. It uses penetrant to apply on the surface of the S690QL rockwell hardness steel plate, then wipes the excess penetrant with the cleaning solution, and then smears the developer. The penetrant remaining in the defect is adsorbed by the developing material, so as to observe the shape of the defect and determine the type of defect. This S690QL rockwell hardness method requires multiple wipes before and after the inspection, the process is more cumbersome, and can not detect internal defects and rough and dirty steel plates.

EN10083-3 42CrMo4 steel plate is a common chromium-molybdenum steel that usually used after quenched and tempered. S690QL rockwell hardness, EN10083-3 42CrMo4 steel plate has high intensity, high hardenability, high fatigue strength and good low-temperature impact toughness. EN10083-3 42CrMo4 steel plate has better performance than 34CrMo4 steel due to the carbon and chromium content is higher.

Our company will accept the product quality objection registration record, pass it to the S690QL rockwell hardness production unit and relevant departments, and timely coordinate the supervision of product S690QL rockwell hardness quality objection. Our company coordinates the relevant department personnel to the customer unit to carry on the investigation, the processing.
