Document Type and Number:
Japanese Patent JPH06142850
Kind Code:
A
Abstract:
PURPOSE: To provide a casting method of 13 Cr steel alloy casting having high corrosion fatigue strength hard, to generate entrapment of a coating and nonmetallic inclusion.
CONSTITUTION: In a molten metal 9 of 13 Cr steel containing 10-17wt.% Cr, a cooling mold 1 having an up and down piercing hole mold 2 is immersed such that its upper opening positions above a molten metal surface.
