Product Description
DIN Ck30/1.1178 Carbon Structural Steel
1: Ck30 Steel Introduction
Ck30 is special steel, and is low temperature of Structural steel in Germany.Structural steel is to point to a specific strength and formability of grades of steel.Formability expressed as a percentage elongation after interruption of tensile test.Structural steel, generally for hosting purposes, in the strength of these USES of sinosteel is an important design criteria.
