The important role of structural steel shapes A36 in life

16Mo3 steel is a kind of European boiler steel plate. 16Mo3 is different from other raw materials when welding. It must be preheated first, and the weld should be kept for about 30 minutes after the welding is completed. structural steel shapes A36, 16Mo3 manganese steel is also an important alloy element steel, it is an important hardenability element. 16Mo3 alloy is a material used at elevated operating temperatures, such as weldable steel in the manufacture of industrial boilers and stainless steel pressure vessels in the petroleum, natural gas and chemical industries.

The company adheres to the "variety, quality and efficiency" road. We have established a technology center, a brand cultivation management system and a quality control system. Now the company has formed an independent innovation system integrating structural steel shapes A36 production, learning, research and marketing. Our company has passed ISO9001 quality management system certification and ISO10012 measurement management system certification.

Quenching is a common heat treatment process. It is the metal heat treatment process in which the structural steel shapes A36 metal workpiece is heated to a proper temperature and kept for a period of time, then immersed in the quenching medium for rapid cooling. Quenching can improve the strength and hardness of steel in a large range, and adjust the coordination between structural steel shapes A36 strength and hardness, plasticity and toughness. Quenching is generally used as the final heat treatment.

During cladding welding of hardfacing wear-resistant steel plate, structural steel shapes A36, preheating and slow cooling should not be adopted. Sometimes, forced cooling measures are even taken to reduce the residence time of weld in the temperature range of 400-850℃ to prevent local chromium deficiency in austenite grain boundary and σ brittle phase in the plate, resulting in 475℃ brittleness, so as to ensure that the weld metal has good mechanical properties and intergranular corrosion resistance.

After sales service support personnel pay attention to commitment in their work. In the process of people to people communication, mutual trust is an important factor for the long-term and stable communication. After sales service personnel must do what they say in the process of communication with customers.
