Title:
MANUFACTURE OF HOT ROLLED STEEL PLATE FOR ENAMEL WITH SUPERIOR FORMABILITY AND FISH SCALE RESISTANCE
Document Type and Number:
Japanese Patent JPS59118814
Kind Code:
A
Abstract:

PURPOSE: To obtain advantageously the titled steel plate by specifying the composition of steel and the ratio of B/N in the steel and by carrying out hot rolling at a relatively low temp.

CONSTITUTION: A steel billet contg., by weight, ≤0.10% C, ≤0.03% Al, ≤0.007% N and 0.0010W0.007% B and having 0.4W2.0 atomic ratio of B/N is heated to 1,000W1,200°C and hot rolled at a temp. above the Ar3 transformation point. A hot rolled steel plate for enamel with superior formability and having the resistance to the generation of fish scale can be obtd. advantageously.
