CF(Crack Free)钢是一种高强度低裂纹敏感性的新钢种,该钢最大优点在于焊前不预热或稍加预热而不产生裂纹,具有优良的焊接性能和低温韧性。为了满足国内压力容器、水电站高压叉管、
CF (Crack Free) steel is a new type of steel with high strength and low crack sensitivity. The biggest advantage of this steel is that it has excellent weldability and low temperature toughness without preheating or slightly preheating without cracking. In order to meet the domestic pressure vessels, high voltage fork pipe hydropower station,
