A573 Grade 58 (A573 Gr 58) steel equivalent

From the name, we can clearly know that seamless pipe is seamless steel pipe, which is different from welded pipe. Seamless pipe is actually a kind of steel with hollow section. Seamless pipe has many advantages, such as: 1, the compressive capacity of seamless pipe is very good, the place with high bearing strength will not crack, and its bearing capacity is very good. 2. Seamless pipe has no welding point, so it is more corrosion-resistant and can bear larger pressure.

The basic principle of A573 Grade 58 (A573 Gr 58) steel equivalent, heat treatment of steel: put the metal workpiece in a certain medium and heat it to a suitable temperature, keep it in this temperature for a certain time, and then cool it at different speeds. Objective: to obtain the desired structure and properties by means of heating, heat preservation and cooling, so as to make the metal workpiece have the required mechanical, physical and chemical properties.
