* Ordinary low alloy steel is a kind of ordinary alloy steel containing a small amount of alloy elements (in most cases, the total amount of w does not exceed 3%). This kind of steel has high strength, good comprehensive properties, corrosion resistance, wear resistance, low temperature resistance, and good cutting and welding properties.
* Under the condition of saving a lot of rare alloy elements (such as nickel and chromium), usually 1 t ordinary low alloy steel can be used for 1.2-1.3 carbon steel, and its service life and scope of use are much longer than carbon steel. Ordinary low alloy steel can be smelted in open hearth furnace and converter with general smelting method, and the cost is close to that of carbon steel.

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.
