During cladding welding of hardfacing wear-resistant steel plate, SA573 Grade 70 carbon steel angle bar, 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.
BBN company is a modern enterprise integrating steel producing, warehousing and logistics, processing and distribution. We are committed to creating a "one-stop steel procurement service" platform.
