Quality requirements of hardox 500 welding

Our company attaches great importance to technical support and after-sales service, and has established a customer service center to provide unified technical support and service for HARDOX 500 welding various engineering projects. Customer service center has a strong technical force of technical service team, composed of a customer service center manager, several HARDOX 500 welding after-sales service personnel, responsible for unified acceptance and processing of local after-sales service needs.

15crmo alloy pipe is a kind of seamless steel pipe, and its performance is much higher than ordinary seamless steel pipe. Because this kind of steel pipe contains more Cr, its high temperature resistance and corrosion resistance are not comparable to other seamless steel pipes, so alloy pipes are widely used in petroleum, chemical, electric power, boiler and other industries.

Try to use HARDOX 500 welding 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 HARDOX 500 welding temperature range is between 450 ℃ and 850 ℃, resulting in chromium poor grain boundary, which is insufficient to resist corrosion.

According to GBT3077, 42CrMo steel chemical composition should be within the range (%): 42CrMo carbon content is 0.38-0.45 (C), Silicon content is 0.17-0.37 (Si), Manganese content is 0.50-0.80 (Mn), Chrome content is 0.90-1.20 (Cr), Molybdenum content is 0.15-0.25 (Mo). The high Cr content contrivutes to high strength of 42CrMo steel, with min. yield strength of 930 Mpa, and min. tensile strength of 1080 Mpa. The common heat treatment for HARDOX 500 welding, 42CrMo steel is quenching and tempering.

The company has our own truck fleet, and can transfer products flexibly and quickly. At the same time, we have large warehouses near the ports of Tianjin and Shanghai, so as to ensure that we can deliver high-quality products to customers in the first time. At the same time, it also greatly reduces the transportation cost, and realizes the double harvest of time benefit and economic benefit. Time guarantee is one of the important strengths of our service.
