15CrMo alloy plate is a heat-resistant steel with pearlite structure, which has high thermal strength (δb≥440MPa) and oxidation resistance at high temperatures, and has a certain resistance to hydrogen corrosion. Due to the high content of Cr, C and other alloying elements in steel, the hardening tendency of SA573 Grade 70 structural steel dimension and 15CrMo alloy plate is obvious and the weldability is poor. After welding, local high temperature tempering treatment should be carried out. The heat treatment process of 15CrMo alloy plate is as follows: the temperature rise rate is 200°C/h, the temperature is raised to 715°C for 1 hour and 15 minutes, the temperature drop rate is 100°C/h, and the temperature is reduced to 300°C before air cooling.

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 SA573 Grade 70 structural steel dimension production, learning, research and marketing. Our company has passed ISO9001 quality management system certification and ISO10012 measurement management system certification.

The SA573 Grade 70 structural steel dimension steel making furnace can only be used as primary refining, and the refining needs to be completed in the refining equipment outside the furnace, which is also called secondary refining. It is mainly through decarburization, desulfuration, denitrification and dephosphorization to improve the cleanness of the steel, to establish a chromium molybdenum low alloy steel with good oxidation resistance and high temperature strength, to remove unwanted harmful impurities from the steel, and to improve the SA573 Grade 70 structural steel dimension internal quality of the steel.

Our SA573 Grade 70 structural steel dimension, hot rolled mild steel sheets offer excellent corrosion resistance property in the server’s environments. The mild steel sheets provide high resistance to nitric and chloride corrosion in sulfide solutions. These SA283 GrC carbon stel plates offer high strength, tensile, yield, mechanical strength, ductility, hardness, toughness, etc. Mild steel sheet is worked very easily in a high-temperature application and show excellent resistance to chloride crossing and cracking stress.

The company specializes in heavy plate cutting, carbon steel pplate processing, carbon plate welding processing and sales of wide and thick steel SA573 Grade 70 structural steel dimension plates. It has high-quality CNC steel plate cutting and processing equipment, a professional technical personnel team, and supporting logistics distribution and after-sales service system. BBN company provides customers with solutions at low prices, high quality, and fast response service.
