(1) Chinese name, low temperature carbon steel; in the machinery industry, LCB is also used to refer to low temperature carbon steel.

(2) LCB (Limited Capacity Buoy), limited capacity buoy

(3) Line Control Block, line [row] control block

(4) Link Control Block, connection control block

(5) Logic Control Block, logic control block

Its chemical composition:

C≤ 0.30; Si≤ 0.60; Mn≤ 1.00; P≤ 0.040; S≤ 0.045; impurity element Cr≤ 0.5; Mo≤ 0.20; V≤ 0.03; Ni≤ 0.50; Cu≤ 0.30;

The total amount of impurities is≤ 1%.

Note: For every 0.01% decrease in C, Mn can be increased by 0.04%, but the maximum Mn cannot be higher than 1.28%.
