The difference between P235GH astm equivalent, Q420D steel and Q460D steel: Q420D steel has good mechanical properties and weldability, good cold and hot workability. Q420D steel is mainly used for manufacturing mining machinery, heavy vehicles, ships, bridges, medium and high pressure boilers, vessels and other large welding and structural parts. p235gh astm equivalent, Q460D steel has high strength, good plasticity and toughness, good weldability and good cold and hot workability. Q460D steel is mainly used for manufacturing engineering machinery components, such as mining machinery, forklift truck, transport vehicle, bridge, medium and high pressure boiler and other large-scale welding structural parts.

The company adopts the p235gh astm equivalent international advanced management system, and has passed the certification of ISO9001 quality management system, ISO14001 environmental management system and GB / T28001-2001 occupational health and safety p235gh astm equivalent management system, and has realized the comprehensive integration of the three systems. In the future development path, the company will adhere to the guidance of scientific development concept, accelerate the implementation of six development strategies, namely, the main business development strategy, cost leading strategy, science and technology innovation strategy, management upgrading strategy, green steel strategy, and Harmonious Co construction strategy, promote the company's sustainable development, and build the company into the most competitive modern steel group.

Try to use p235gh astm equivalent high-quality alkaline covered electrode as much as possible, and don't use inferior electrode to save money. According to the theory of chromium poor, chromium carbide will be precipitated on the upper edge of the grain boundary of the weld and heat affected zone when the p235gh astm equivalent temperature range is between 450 ℃ and 850 ℃, resulting in chromium poor grain boundary, which is insufficient to resist corrosion.

Vanadium mainly exists in the form of carbide in p235gh astm equivalent and so on steel. Its main function is to refine the structure and grain size of steel and reduce the strength and toughness of steel. When the solid solution is dissolved at high temperature, the hardenability is increased; conversely, if it is in the form of carbide, the hardenability is reduced. Vanadium increases the tempering stability of quenched steel and produces secondary hardening effect. The vanadium content in steel, except high speed tool steel, is generally less than 0.5%.

As one of the large professional metallurgical manufacturers in China, the strength of the brand, quality assurance, professional after-sales. Every day we are making unremitting efforts to challenge higher quality p235gh astm equivalent products and more satisfactory services. Customer demand is our pursuit, and win customer satisfaction with quality. BBN after-sales team is responsible to solve the problem of technical support and quality, service complaints.
