192 is the steel of carbon structural steel, which is a kind of alloy steel and carbon steel. The carbon content is about 0.05%~0.70%, and some can reach up to 0.90%. It can be divided into ordinary carbon structural steel and high-quality carbon structural steel.

Now the common round steel processes are hot rolling, forging and cold drawing. The steel quality and application scope of these three processing modes will also have some differences. For example, the specification of hot rolling is generally 5.5-250MM, and the appropriate steel can be selected according to the actual needs.
Generally, parts are manufactured by machinery or used as seamless steel pipe blanks, and steel is also used in some building construction.
Round steel has relatively high strength, high hardenability and very good toughness, so its pressure bearing capacity is also guaranteed. Even if it is used at high temperature, the creep strength is high and the durability is also guaranteed.

Round steel belongs to carbon structural steel for construction and machinery, while square steel belongs to carbon structural
steel for machinery. Both of them are simple section steel, and their section shapes are respectively round and square. Low carbon is mainly used for
drawing wire, forging rivets, bolts, nuts and other metal products of raw materials. Medium carbon round steel and square steel
are generally used to make mechanical structural parts.

Warehouse Storage

Shandong Jintuo Metal Materials Co., Ltd is located in Liaocheng City, the capital of steel tubes. It is a large enterprise specializing in the sales of carbon steel, stainless steel, galvanized color coated products, and copper and aluminum.Our company adopts a flexible business approach and management mechanism to provide good services to customers, while also considering the interests of the owner and the project, in order to ensure the quality of the project.

Performance and application of material ST37: the material has good performance, that is, through cold rolling, it can obtain cold rolled strip and steel plate with thinner thickness and higher precision, with high straightness, high surface finish, clean and bright surface of cold rolled plate in Taiwan Strait, easy to be coated, various varieties, wide application, high stamping performance, non aging, and low yield point.
