Carbon Steel
High-quality welded pipes that stand the test of time
Products Description
(1) According to the carbon content of carbon steel can be divided into
① low carbon steel (WC ≤ 0.25%), ② medium carbon steel (WC0.25% - 0.6%)
② medium carbon steel (WC0.25% -0.6%)
③ high-carbon steel (WC> 0.6%)
(2) according to the quality of steel classification
① ordinary carbon steel (sulfur content ≤ 0.050%, phosphorus content ≤ 0.045%)
② high-quality carbon steel (sulfur content ≤ 0.040%, phosphorus content ≤ 0.040%)
③ high-quality carbon steel (sulfur content ≤ 0.030%, phosphorus content ≤ 0.035%)
(3) according to the use of carbon steel can be divided into
① carbon structural steel, mainly used to make a variety of engineering structures and machine parts, generally low carbon steel.
② carbon tool steel, mainly used to make a variety of cutting tools, gauges, molds, etc., generally high-carbon steel.
