ASTM A36 rimmed steel plate descriptionCarbon steel ASTM A36 rimmed steel plate, as the name implies, is a steel plate made of hot rolling of ordinary carbon structural steel. Rimmed steel is a type of ASTM A36 steel with incomplete deoxidation. The molten steel has a high oxygen content. When molten steel is injected into the ingot mold, the carbon-oxygen reaction generates a large amount of gas, which causes the molten steel to boil.
The carbon content of rimmed steel is low, and because ferrosilicon is not used for deoxidation, the silicon content in steel is often <0.07%. The outer layer of rimmed steel is crystallized in a boiling state, so the surface layer is pure and dense, the surface quality is good, and the processing performance is good. ASTM A36 rimmed steel plate does not have large concentrated shrinkage cavities, uses less deoxidizer, and the cost of steel is low. The rimmed steel core has many impurities, severe segregation, uneven mechanical properties, high gas content in the steel, low toughness, cold brittleness and high aging sensitivity, and poor welding performance, so it is not suitable for manufacturing to withstand impact load interception welded structural parts and other important structural parts that work at low temperatures.
ASTM A36 rimmed steel plate application: the rimmed steel plate is used to manufacture various stamping parts, building and engineering structures, and some less important machine structures and parts.
