15. The Raw Materials --all come from parent company TISCO
TISCO Stainless steel smelting uses three-step refining process. It can
ensure high steel purity less harmful elements and other characteristics (S ≤
0.005%, P ≤ 0.020%). Through a protective atmosphere ESR, high-quality
raw material can be produced to provide high-quality stainless steel tube.
