304 stainless steel screw anchor

Welding characteristics of heat-resistant steel for furnace In general, the material of Metallic Anchors is austenitic heat-resistant steel. In the cement industry, the most commonly used are Refractory Anchors. Usually, the bifurcated part of the Y Anchors needs to be soldered. This welding belongs to the welding between austenitic steel and austenitic steel. The weldability of austenitic heat-resistant steel is much better than that of ferritic heat-resistant steel and martensitic heat-resistant steel. However, austenitic heat-resistant steel still has welding hot cracks and grain growth in the heat-affected zone, and there is a tendency to embrittle at 475 ° C, and there is an embrittlement phase at 600-850 ° C for a long time. Austenitic heat-resistant steel has a small thermal conductivity and a large expansion coefficient. In the case of local high-speed heating and cooling, a large welding stress will be formed at the joint.
