Product Description

Product Description

JIS SS330  GB Q215	Due to moderate carbon content, good comprehensive performance, and a good combination of strength, plasticity, and welding properties, it is the most widely used. A large number of buildings and engineering structures are used. It is used for manufacturing steel bars or building factory buildings, high-voltage transmission towers, bridges, vehicles, boilers, containers, ships, etc., and is also widely used as mechanical parts with low performance requirements. Grade C and D steels can also be used as certain professional steels.
ASTM 1015 JIS SS400  GB Q235	SS400 steel is a carbon structural steel. It is equivalent to the A3 and C3 steels in the old standard GB700-79, and is the trademark of the Russian TOCT. The Q in the steel grade represents the yield strength. Generally, this steel is used directly without heat treatment. It can be used for various grinding tool handles and other unimportant grinding tool parts.
JIS SM400  GB Q255	SM400 is a carbon structural steel. It has good strength, plasticity, and toughness, good welding performance, and cold and hot pressure processing performance. Used for manufacturing parts with low strength requirements, such as bolts, keys, rocker rods, shafts, pull rods, and various steel sections and plates for steel structures.
JIS SS490 SS500 GB Q275	SS490 is a carbon structural steel with high strength, good plasticity, and machining performance, as well as certain welding properties. Small parts can be hardened and strengthened, and are mostly used to manufacture parts requiring high strength, such as gears, shafts, sprockets, keys, bolts, nuts, agricultural machine section steels, conveyor chains, and chain links. It is mainly used for manufacturing important mechanical components in construction and bridge engineering, and can be used instead of high-quality carbon steel,
JIS SM520B GB Q460	High strength, high comprehensive mechanical properties and good toughness after normalizing, normalizing and tempering, or quenching and tempering. It is mainly used for various large engineering structures and lightweight structures requiring high strength and large loads. It is widely used in various types of construction machinery, such as drilling machines, electric shovels, electric backhoes, mining vehicles, excavators, loaders, bulldozers, various types of cranes, coal mine hydraulic supports, and other mechanical equipment and other structural components for mining and various engineering construction.
ASTM 1024 DIN ST52 GB 16Mn Q345	1024 seamless steel pipe is a low alloy high strength structural steel Good comprehensive performance, low temperature performance, cold stamping performance, welding performance and machinability. Used in mining, transportation, chemical and other machinery.
