Patent ID: 7416619

Claim:
A process of manufacturing a kitchen utensil from an alloy, comprising the steps of: a. stamping the alloy on a punch to form a wafer having a diameter, Φ; b. oil rolling the alloy; c. forming the kitchen utensil using an elongation process on the alloy; and d. trimming and surface treating the formed kitchen utensil, wherein the alloy has a composition (in wt %) consisting of: Cr 16-19, C≦0.025, Si≦1.00, Mn≦1.00, N≦0.02, Ni≦0.60, Ti≦0.75, Mo 0.75-1.50 and the balance of Fe, wherein the kitchen utensil includes a cookware, dishware and culinary vessel, wherein the cookware is integrative, wherein the kitchen utensil is a straight body and cut edge cooker with a single base, wherein the punch is an about 100-ton punch, wherein the diameter Φ of the wafer is about 360 mm, wherein in the elongation process, the blankholder force is about 10 MPa, the angle of the male die is R16 that characterizes the male die having a corner radius R=16 mm, and the angle of the female die is R10 that characterizes the female die having a corner radius R=10 mm.
