Q355NHD is a weather-resistant structural steel used in construction, bridges, and railway vehicles. Q represents yield strength, NH represents weather resistance, and D represents quality grade (A, B, C, D, E) composition. heat treatment of P355GH steel is an atmospheric corrosion-resistant steel plate with the properties of high-quality steel such as strength, ductility, forming, welding, abrasion, high temperature and fatigue resistance.

heat treatment of p355gh, 30CrMnSiA steel plate is a kind of low alloy high strength steel with medium carbon, high strength and good weldability. After quenching and tempering, 30CrMnSiA steel has high strength, enough toughness and good hardenability. After quenching and tempering, 30CrMnSiA steel can be used as grinding wheel shaft, gear and sprocket. 30CrMnSiA steel has good processability, small deformation and good fatigue resistance. 30CrMnSiA steel is usually used for shaft, piston parts, etc. It is used for various special wear-resistant parts of automobiles and airplanes.

Penetration testing technology is only suitable for detecting surface defects. It uses penetrant to apply on the surface of the heat treatment of p355gh 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 heat treatment of p355gh 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.

The company adheres to the business philosophy of "good quality, customer first, honesty and trustworthiness", and strives to provide customers with high-quality heat treatment of p355gh products and excellent services. Our company's products heat treatment of p355gh are widely used in petroleum, chemical, power station, boiler and other industries, mainly used in reactors, heat exchangers, separators, spherical tanks, oil and gas tanks, liquefied gas tanks, nuclear energy reactor pressure shells and other equipment.

In addition to quality assurance, service is also important for the competition of steel suppliers. All the after-sales service personnel of the company have received professional training and assessment.
