Type	Grade of steel	Thickness (mm)	Standard	Performance	Application
Common carbon structural steel	Q235A/B	8-90	GB/T 700-2006	Compare with the high quality carbon structural steel, the common carbon structural steel has less strict requirements for carbon content, performance range, and the limit of the residual elements such as phosphorus and sulphur. The number of the grade, 235, means the yield strength under 16mm is equal or greater than 235 MPa.	This kind of steel plate has been widely used for the welded, riveted or bolted steel structure equipment, manufacturing the metal components that can sustain static load, the minor mechanical parts that do not need thermal treatment and the common weldments.
Common Low Alloy Steel	Q345A/B	8-80	GB/T 1591-2008	Q345A/B steel is equivalent to the old Chinese grade “16Mn”. Compare with Q235 steel, the strength of the steel has increased 50MPa, but still keeps the same plasticity. Yield strength: ≤16mm, greater than 345MPa; 16-40mm, greater than 335MPa; 40-63mm, greater than 325MPa; 63-80mm, greater than 315MPa. The tensile strength is between 450MPa and 630MPa. The elongation is greater than 17%. The impact testing: Q345A doesn’t do the impact testing. Q345B does the test under the temperature of 20℃, and the result is greater than 34J.	The Q345A/B steel plate normally used for the common engineering components.
High Quality Carbon Steel	Q235C/D	8-80	GB/T 700-2006	The carbon content is less than 0.25%. The high quality carbon steel has low contents of P, S and the inclusions. Moreover, except Si, Mn, the high quality carbon steel doesn’t have other alloying elements (other than the impurities). The properties improvement of the high quality carbon steel mainly depends on the carbon elements. And the high quality carbon steel has better plasticity and toughness.	Among all kinds of high quality carbon steels, 20, 25 steel are low carbon steel. They have a good plasticity, which makes them easy to drawing, stamping, extruding, forging, and welding. 20 steel has the widest application. It often used to manufacture bolt, nut, washer, small axle, stamping parts and weldments, sometimes, it also be used to make carburized components. The hardness of 30, 45, 50 steel can be dramatically improved after quenching. And the 45 steel is the most typical one among them. The 45 steel not only has higher strength and hardness, but also maintain better plasticity and toughness. In another word, 45 steel has an excellent overall performance. 45 carbon steel has the widest application in mechanical structure manufacturing, It often used to manufacture axle, lead screw, wheel gear, connecting rod, jacket sleeve, key, the crucial screw and nut, etc.
	20, 25	8-60	GB/T 711-2008
	30, 45, 50	8-60	GB/T 711-2008	30, 40, 50 steel are medium carbon steel. Because of the pearlite content in the steel increased, the strength and rigidity of 30, 40, 50 steel are improved. Therefore, the 30, 40, 50 steel can be thermally processed.
Low Alloy Steel	Q345C/D/E	8-80	GB/T 1591-2008	The number of the grade means the minimum value of the yield strength under 16mm. The low alloy steel intends to improve the strength and toughness of the steel by adding a balanced amount of the alloying elements such as Mn, Nb, V, etc. Compare with the carbon structural steel, using the low alloy steel can reduce the size and weight of the structural parts.	The low alloy steel has been widely used for the construction of plants, normal buildings and all kinds of construction machinery, such as mining machinery, project construction machinery and its structural parts.

Low Alloy High Strength Steel	Q420/Q460	8-60
	Q550	8-60		The yield strength of the low alloy high strength steel is between 530MPa and 690MPa. Anson low alloy high strength steel adopts the low carbon bainitic technology, which insures good strength, roughness and welding performance.	Anson low alloy high strength steel is used to make the welded structures of the heavy machinery and mining machinery that can sustain the dynamic load.

Common Ship Building Plate	A/B/D	10-38	The certification of nine countries’ classification societies. (LR, GL, DNV, BV, NK, ABS, CCS, KR RINA)	There are A, B, D three grades of the steel which used for the general strength hull structure. These three grades of common ship plate share the same yield strength (no less than 235MPa) and tensile strength ( 400-520MPa). But the impact energy under different temperatures are different.	Used to make hull structures.
