The influence of Ce element on SPA-H weathering steel

It is well known that SPA-H weathering steel is one of the main raw materials of container plate. The addition of Ce  elements in SPA-H weathering steel is an effective method to improve the cleanliness of molten steel, the shape of inclusions and the strength and toughness of SPA-H weathering steel materials. the bellowing is The influence of Ce element on SPA-H weathering steel.

SPA-H weathering steel After adding Ce element , the strength and toughness of the steel significantly increase the yield ratio, which increases the seismic performance of SPA-H weathering steel. When the Ce soil content of SPA-H weathering steel is 0.020%, SPA-H The room temperature tensile and yield strength and elongation of weathering steel reached 766.1 and 661.1Mpa, respectively, 45.8%, which were 21.9%, 32.2%, and 96.6% higher than Ce, respectively. The impact energy Ak was 281J, and the Ce content was 0. The style has improved by 75.6%.
