Title:
MANUFACTURE OF JOINED STEEL STOCK FOR HIGH CARBON STEEL AND LOW CARBON-LOW ALLOY STEEL
Document Type and Number:
Japanese Patent JP2500944
Kind Code:
B2
Abstract:
PURPOSE: To prevent crack in a joined interface by combining a high carbon steel and a low carbon.low alloy steel with steel stock satisfying the specific expression with respect to the average carbon content of carbon in the high carbon steel side and carbon in the low carbon.low alloy steel side and the component contents except carbon in the low carbon.low alloy steel side at the time of joining the high carbon steel and the low carbon.low alloy steel.
CONSTITUTION: The high carbon steel containing 0.6-1.0% carbon and the low carbon.low alloy steel containing ≤0.5% carbon, are joined. At this time, the joining steel stock of high carbon steel and low carbon.low alloy steel is made to the steel stock satisfying the expression 1 with respect to the average carbon content of carbon in the high carbon steel side and carbon in the low carbon.low alloy steel side and the component contents except the carbon in the low carbon.low alloy steel side. By this method, the crack in the joined interface and lowering of fatigue damaging resistance caused by the carbon diffused at the joined part between the high carbon steel and the low carbon.low alloy steel can be prevented.
